FAQ

I seguenti prodotti possono essere sterilizzati in autoclave (fino a 135 °C):

• SmartPeg Mount
• SmartPeg riutilizzabile
• Sonda (IDx)

Si ricorda che gli SmartPeg monouso sono dispositivi monouso e non possono essere sterilizzati in autoclave.

Impianti diversi richiedono SmartPeg specifici per garantire una misurazione accurata. Ogni SmartPeg corrisponde a un particolare sistema implantare e tipo di connessione.

È possibile trovare lo SmartPeg corretto per il proprio impianto nella SmartPeg Reference Guide: fare clic qui per accedervi.

No. Non deve essere utilizzato un dispositivo dinamometrico per serrare lo SmartPeg.

Gli SmartPeg devono sempre essere montati con lo SmartPeg Mount e serrati a circa 4–6 Ncm, generalmente definiti serraggio manuale.

Questo assicura che lo SmartPeg sia correttamente posizionato senza rischiare di danneggiare la connessione implantare.

L’ISQ deve essere sempre misurato in due direzioni, poiché la stabilità implantare può variare in base alla quantità di osso circostante nelle diverse direzioni. Misurare da due angolazioni consente di rilevare sia la direzione più stabile sia quella meno stabile.

A tal fine, eseguire una misurazione in direzione bucco-linguale e una in direzione mesio-distale. Questi due valori ISQ rappresentano le diverse direzioni di stabilità. Talvolta i valori sono identici, talvolta differiscono.

Se le due misurazioni differiscono, fare sempre riferimento al valore ISQ più basso, poiché riflette la direzione più debole e fornisce quindi l’informazione clinicamente più rilevante sulla stabilità implantare.

Osstell misura la stabilità implantare mediante Analisi della Frequenza di Risonanza (RFA). Il piccolo SmartPeg fissato all’impianto ha un minuscolo magnete sulla parte superiore. Quando la sonda invia impulsi magnetici, lo SmartPeg inizia a vibrare, come un diapason molto piccolo.
Come funziona:

1. Lo strumento invia impulsi magnetici
Questi impulsi fanno vibrare lo SmartPeg senza toccarlo.

2. La vibrazione cambia in base alla stabilità implantare

– Un impianto stabile (con buon supporto osseo) fa vibrare lo SmartPeg più velocemente.

– Un impianto meno stabile lo fa vibrare più lentamente.

3. Il dispositivo converte la vibrazione in un valore ISQ

– Maggiore stabilità → frequenza più alta → ISQ più alto

– Minore stabilità → frequenza più bassa → ISQ più basso

Il processo richiede meno di un secondo e il valore ISQ viene visualizzato immediatamente.

Diversi fattori possono causare valori ISQ inattesi o l’assenza di una lettura:

1. Uso o condizioni non corretti dello SmartPeg
• SmartPeg monouso: destinato a una sola seduta di trattamento e a un solo paziente. Riutilizzarlo può causare usura delle filettature e misurazioni non affidabili.
• SmartPeg riutilizzabile: assicurarsi che sia stato pulito e ispezionato correttamente e che non sia danneggiato. Usura, deformazione o contaminazione possono comprometterne le prestazioni.

2. Selezione del tipo di SmartPeg errato
Assicurarsi di avere selezionato il tipo di SmartPeg corretto per lo specifico sistema implantare e la relativa connessione. Consultare la SmartPeg Reference Guide.

3. Tessuti o detriti nella connessione implantare
Frammenti ossei, tessuti molli o liquidi tra l’interfaccia implantare e lo SmartPeg possono impedirne il corretto posizionamento. Pulire accuratamente la connessione protesica dell’impianto prima di applicare lo SmartPeg.

4. Interferenze elettromagnetiche
Fonti vicine di disturbo elettromagnetico possono interrompere la misurazione. Se possibile, rimuovere o spegnere la fonte.

5. Posizionamento errato dello strumento di misura
Tenere la punta dello strumento a 2–4 mm dallo SmartPeg e orientarla correttamente verso la parte superiore del peg con un angolo di circa 45°. Non toccare il magnete.

È possibile registrare l’ISQ a livello dell’abutment (moncone) in OsstellConnect, ma per ottenere valori accurati è importante seguire la corretta procedura clinica di misurazione.

Come misurare l’ISQ a livello dell’abutment

1. Eseguire prima una misurazione a livello implantare, prima di posizionare l’abutment.
2. Nella stessa seduta, misurare nuovamente a livello dell’abutment utilizzando uno SmartPeg destinato alla misurazione a livello dell’abutment.
3. Determinare l’offset annotando la differenza tra l’ISQ a livello implantare e quello a livello dell’abutment. Questo offset rimane stabile durante la guarigione e deve essere utilizzato per interpretare le misurazioni di controllo.
4. In tutte le visite successive, misurare sull’abutment e applicare lo stesso offset per comprendere il reale ISQ implantare.

Come registrare la misurazione in OsstellConnect:

1. Accedere all’archivio pazienti, selezionare il paziente e l’impianto nell’odontogramma. Fare clic su “Add abutment”, scegliere l’abutment e salvare.
2. Selezionare “Measure stability” e scegliere “Abutment” in Measurement level. Misurare sull’abutment come a livello implantare e salvare.
3. Per rivedere l’andamento della stabilità, aprire la scheda Stability e attivare “Show abutment”. È anche possibile attivare “Show details” per visualizzare i valori ISQ bucco-linguali e mesio-distali.

Per una spiegazione più dettagliata e indicazioni cliniche, consultare qui il nostro post del blog.

Sì, può essere sterilizzato con un ciclo Prion a 134 °C per 18 minuti.

Sia con uno SmartPeg monouso sia con uno riutilizzabile, il montaggio deve essere sempre eseguito con lo SmartPeg Mount e serrato a circa 4–6 Ncm, generalmente definito serraggio manuale.

Ciò garantisce un corretto posizionamento e misurazioni ISQ accurate senza rischiare di danneggiare l’impianto o lo SmartPeg.

Sì. È possibile utilizzare SmartPeg monouso e riutilizzabili durante la stessa seduta di trattamento. L’unico requisito è utilizzare lo SmartPeg Type corretto per lo specifico impianto o abutment (moncone) da misurare.

Il fatto che lo SmartPeg sia monouso o riutilizzabile non influenza la misurazione.

Sì, purché ne siano mantenute integrità e prestazioni.

Osstell è inoltre l’unica azienda a offrire sia SmartPeg monouso sterili sia SmartPeg riutilizzabili in alluminio, supportati da oltre 1.500 studi pubblicati sul metodo ISQ.

Con la scala ISQ originale Osstell e gli SmartPeg non sono necessarie tabelle di conversione o fattori di correzione. Il valore ISQ misurato è il valore effettivo, indipendentemente dall’uso di uno SmartPeg monouso o riutilizzabile.

Gli SmartPeg sono forniti in formati di confezionamento diversi a seconda che siano monouso o riutilizzabili:

SmartPeg monouso

– Forniti sterili.
– Confezionati in scatole da 5 pezzi, in un sistema di barriera sterile singolo con imballaggio esterno protettivo.
– Destinati a una sola seduta di trattamento e non riutilizzabili.

SmartPeg riutilizzabili

– Forniti non sterili in confezione individuale.
– Devono essere puliti, disinfettati e sterilizzati prima del primo utilizzo clinico e dopo ogni utilizzo successivo. (Vedere la guida rapida su osstell/ifu).

SmartPeg Mount

– Fornito non sterile con lo strumento.
– Può essere acquistato separatamente, in confezioni da 5.
– Deve anch’esso essere pulito, disinfettato e sterilizzato prima dell’uso e tra un paziente e l’altro. (Vedere la guida rapida su osstell/ifu).

Sì. Gli SmartPeg riutilizzabili e monouso sono progettati per essere facilmente distinguibili visivamente:
– Lo SmartPeg monouso è fornito sterile, ha un magnete color alluminio (non colorato) e non presenta identificatori marcati al laser sul corpo.
– Lo SmartPeg riutilizzabile ha un magnete nero sulla parte superiore e riporta sul corpo i numeri Type e LOT marcati al laser, per identificazione e tracciabilità.

Lo SmartPeg riutilizzabile può essere utilizzato fino a 20 cicli di ricondizionamento convalidati, purché ne siano mantenute integrità e prestazioni.
Se l’ispezione rileva usura, deformazione, corrosione, filettature danneggiate o perdita di compatibilità funzionale, lo SmartPeg deve essere scartato, anche se è stato trattato meno di 20 volte.
Lo SmartPeg monouso è destinato a una sola seduta di trattamento e non deve essere ricondizionato.

Lo SmartPeg riutilizzabile è progettato con speciali rivestimenti protettivi: uno sul corpo dello SmartPeg e un altro, nero, sul magnete. Questi rivestimenti resistono a umidità, sostanze chimiche di pulizia, usura e corrosione, preservando le prestazioni dello SmartPeg per il numero convalidato di cicli di ricondizionamento.
Lo SmartPeg riutilizzabile si distingue facilmente dalla versione monouso: ha un magnete nero e i numeri LOT e Type sono marcati al laser sul corpo per una chiara identificazione.

Yes, it can be sterilised with a Prion cycle at 134 °C for 18 minutes.

Whether you are using a single-use or a reusable SmartPeg, it should always be installed using the SmartPeg Mount and tightened to approximately 4–6 Ncm – typically described as finger tight. This ensures proper seating and accurate ISQ measurements without risking damage to the implant or the SmartPeg.

Yes. You can mix single-use and reusable SmartPegs during the same treatment session. The only requirement is that you use the correct SmartPeg Type number for the specific implant or abutment you are measuring.

Whether the SmartPeg is single-use or reusable does not affect the measurement.

Yes, as long as its integrity and performance are maintained.

Osstell is also the only company offering both a sterile single-use and a reusable SmartPeg made of aluminium, supported by more than 1,500 published studies on the ISQ method.

With the Osstell original ISQ scale and SmartPegs, no conversion tables or correction factors are needed. The measured ISQ value is the true value, regardless of whether you use a single use or a reusable SmartPeg.

SmartPegs are supplied in different packaging formats depending on whether they are single-use or reusable:

Single-use SmartPegs

• Delivered sterile.
• Supplied in boxes of 5 pieces, in a single sterile barrier system with protective outer packaging.
• Intended for one treatment session only and must not be reused.

Reusable SmartPegs

• Delivered nonsterile in individual packaging.
• Must be cleaned, disinfected and sterilized before the first clinical use and after every subsequent use. (See quickguide at osstell/ifu).

SmartPeg Mount

• Delivered nonsterile with the instrument.
• Can be purchased separately, in package of 5.
• Must also be cleaned, disinfected and sterilized before use and between patients. (See quickguide at osstell/ifu).

Yes. The reusable and single use SmartPegs are designed so they can be easily distinguished visually:

• The single-use SmartPeg is supplied sterile, has an aluminium coloured (non coloured) magnet, and does not include any laser marked identifiers on the body.
• The reusable SmartPeg has a black magnet on top and carries laser marked Type and LOT numbers on the body for identification and traceability.

The reusable SmartPeg can be used for up to 20 reprocessing cycles, as long as its integrity and performance are maintained.

If inspection reveals wear, deformation, corrosion, damaged threads, or any loss of functional compatibility, the SmartPeg must be discarded, even if it has been processed fewer than 20 times.

The single-use SmartPeg is intended for one treatment session only and must not be reprocessed.

The reusable SmartPeg is engineered with special protective surface coating – one on the SmartPeg body and another black protective coating on the magnet. These coatings provide resistance to moisture, cleaning chemicals, wear, and corrosion, ensuring that the SmartPeg maintains its performance throughout the validated number of reprocessing cycles.

The reusable SmartPeg can easily be distinguished from the single use version: it has a black magnet, and its LOT and Type number are laser marked on the body for clear identification.

Prima del primo utilizzo clinico e dopo ogni utilizzo, i prodotti riutilizzabili devono essere puliti, disinfettati e sterilizzati secondo le istruzioni della guida rapida disponibile qui: Osstell.com/ifu.

You can record ISQ at abutment level in OsstellConnect, but it is important to follow the correct clinical measurement procedure to obtain accurate values.

How to measure ISQ at abutment level

1. Perform an implant level measurement first, before placing the abutment.
2. Measure again at abutment level during the same session, using a SmartPeg made for abutment level measuring.
3. Determine the offset by noting the difference between implant level and abutment level ISQ. This offset remains stable throughout healing and should be used when interpreting follow-up measurements.
4. For all subsequent visits, measure on the abutment and apply the same offset to understand the true implant ISQ.

How to record the measurement in OsstellConnect:

1. Go to the patient’s register, select the patient and the implant in the tooth chart. Click ‘Add abutment’, choose the abutment, and save.
2. Select ‘Measure stability’ and choose ‘Abutment’ under Measurement level. Measure on the abutment as you would at implant level and save.
3. To review the stability trend, open the Stability tab and toggle ‘Show abutment’. You can also enable ‘Show details’ to view buccal–lingual and mesial–distal ISQ values.

For a more detailed explanation and clinical guidance, see our blog post here.

ISQ should always be measured in two directions, because implant stability can vary depending on the amount of surrounding bone in different directions. Measuring from two angles ensures that both the most and the least stable directions are captured.
To do this, take one measurement in the buccal-lingual direction and one in the mesial-distal direction. These two ISQ values represent the different stability directions. Sometimes the values are identical; sometimes they differ.
If the two measurements differ, always rely on the lowest ISQ value, as it reflects the weakest direction and therefore provides the most clinically relevant information about implant stability.

There are currently thousands of articles where Osstell devices were used in the study, published in scientific papers. These abstracts could be found in our searchable database under “Resources/Scientific database“.

The Osstell ISQ scale is based on outcomes from these studies, all performed using Osstell instruments and aluminium SmartPegs.

No. A torque device should not be used to tighten the SmartPeg.

SmartPegs should always be mounted using the SmartPeg Mount and tightened to approximately 4–6 Ncm, which is typically described as finger tight.

This ensures the SmartPeg is seated correctly without risking damage to the implant connection.

Osstell measures implant stability using Resonance Frequency Analysis (RFA). The small SmartPeg that you attach to the implant has a tiny magnet on top. When the probe sends magnetic pulses, the SmartPeg starts to vibrate – similar to a very small tuning fork.
How it works:

1. The instrument tip sends magnetic pulses
   These pulses make the SmartPeg vibrate without touching it.
2. The vibration changes depending on how stable the implant is
   – A stable implant (good bone support) makes the SmartPeg vibrate faster.
   – A less stable implant makes it vibrate slower.
3. The device converts this vibration into an ISQ value
   – Higher stability → higher frequency → higher ISQ
   – Lower stability → lower frequency → lower ISQ

It takes less than a second, and the ISQ value is shown immediately.

Yes. The ISQ value can be affected if the SmartPeg is not mounted correctly.

For accurate measurements, the SmartPeg should be attached finger tight using the SmartPeg Mount, which corresponds to about 4–6 Ncm.

At this level, the SmartPeg has firm, stable contact with the implant, and the resulting ISQ value is consistent – typically within ±2 ISQ units.

• If the SmartPeg is not fully seated:
  The contact becomes unstable, and the ISQ value can appear artificially low, or you don’t receive any value.
• If too much force is applied:
  Overtightening does not improve accuracy. It may damage the SmartPeg threads.
  – A reusable SmartPeg may be damaged so it cannot be used again.
  – A single use or reusable SmartPeg may have its threads deformed, which can lead to inaccurate measurements during that session or, in worst case a broken SmartPeg.

In short: finger tight (4–5 Ncm) is enough to ensure stable contact and reliable ISQ readings.

If no ISQ value appears, it usually means the SmartPeg’s vibration is not being detected clearly by the instrument. Several factors can cause this, and most are easy to resolve:

1. Distance to instrument is too great
   The instrument should normally be held 2–4 mm from the magnet on top of the SmartPeg. Do not touch the magnet. If no value appears, move the instrument closer until the signal is detected.
2. Angle needs adjustment
   The magnetic field is directional, so the orientation of the instrument matters. Measurements should be taken at approximately a 45° angle relative to the top of the SmartPeg.
3. Ensure you have the correct SmartPeg Type for the specific implant
   Use this link to find the correct SmartPeg Type: Find my SmartPeg
4. Soft tissue damping
   Surrounding tissue can sometimes dampen the vibration more than expected. Holding the instrument a bit closer usually compensates for this.
5. The implant platform is not clean
   Ensure the implant platform is clean and free of debris, so the SmartPeg seats properly and transmits its vibration.
6. The SmartPeg is worn or damaged
   • If you are using a reusable SmartPeg, make sure it has been inspected before use and that it is within 20 reprocessing cycles. A reusable SmartPeg that is worn out, bent, or has damaged threads will not vibrate correctly — and the instrument may not be able to pick up a reading.
   • A single‑use SmartPeg is intended for one treatment session only.
   • Ensure the SmartPeg is properly seated on the implant and that it is not in contact with surrounding tissue, as this can prevent accurate signal detection and may result in no ISQ value or an incorrect one.
7. Electromagnetic interference
   Strong electromagnetic noise sources nearby may disturb the measurement. (See the FAQ on “Electromagnetic noise” for details.)

The following products may be autoclaved (over-pressurized steam up to 135 deg Celsius):

• SmartPeg Mount
• Reusable SmartPeg
• Probe (IDx)

Please note that single-use SmartPegs are disposable and cannot be autoclaved!

Different implants require specific SmartPegs to ensure accurate measurement. Each SmartPeg is matched to a particular implant system and connection type.

Alcune spiegazioni possibili includono:

Riutilizzo degli SmartPeg: Gli SmartPeg sono monouso e devono essere utilizzati per eseguire una o più misurazioni in una sessione di trattamento e su un solo paziente. Riutilizzarli in modo ripetuto può provocare letture errate a causa dell’usura delle filettature degli SmartPeg in alluminio morbido.

Tipo errato di SmartPeg selezionato per l’impianto: Consultare l’elenco di riferimento degli SmartPeg alla pagina osstell.com/smartpegguide

Presenza di tessuto osseo o tessuto molle tra SmartPeg e impianto: Assicurarsi di pulire l’innesto protesico dell’impianto prima di collegare lo SmartPeg.

Interferenze elettromagnetiche: Rimuovere la fonte di interferenze elettromagnetiche.

La sonda è tenuta troppo lontana dallo SmartPeg: Tenere la sonda a una distanza di 2-4 mm dallo SmartPeg.

Although it is possible to use the Osstell Beacon directly, depending on the status of the built-in rechargeable battery, it is recommended to charge the battery for at least 3 hours before using the Osstell Beacon instrument.

The Osstell Beacon is activated by a built-in motion sensor. As soon as the motion sensor detects movement, the Osstell Beacon will start-up and shortly show battery status and then be ready for measurement in the BL (Buccal – Lingual) direction, which is indicated in the upper display.

The Osstell Beacon will start to measure, indicated by an audible sound, when near an Osstell SmartPeg or Test peg due to a built-in magnetic detector that senses the magnet on the top of the Osstell SmartPeg/TestPeg. Measured data will be shown in the upper display combined with a colored light indication below the tip.

1. Distance to instrument is too great
   The instrument should normally be held 2–4 mm from the magnet on top of the SmartPeg. Do not touch the magnet. If no value appears, move the instrument closer until the signal is detected.
2. Angle needs adjustment
   The magnetic field is directional, so the orientation of the instrument matters. Measurements should be taken at approximately a 45° angle relative to the top of the SmartPeg.
3. Ensure you have the correct SmartPeg Type for the specific implant
   Use this link to find the correct SmartPeg Type: Find my SmartPeg
4. Soft tissue damping
   Surrounding tissue can sometimes dampen the vibration more than expected. Holding the instrument a bit closer usually compensates for this.
5. The implant platform is not clean
   Ensure the implant platform is clean and free of debris, so the SmartPeg seats properly and transmits its vibration.
6. The SmartPeg is worn or damaged
   • If you are using a reusable SmartPeg, make sure it has been inspected before use and that it is within 20 reprocessing cycles. A reusable SmartPeg that is worn out, bent, or has damaged threads will not vibrate correctly — and the instrument may not be able to pick up a reading.
   • A single‑use SmartPeg is intended for one treatment session only.
   • Ensure the SmartPeg is properly seated on the implant and that it is not in contact with surrounding tissue, as this can prevent accurate signal detection and may result in no ISQ value or an incorrect one.
7. Electromagnetic interference
   Strong electromagnetic noise sources nearby may disturb the measurement. (See the FAQ on “Electromagnetic noise” for details.)

No. The Osstell measurement does not affect the implant. The instrument only makes the SmartPeg vibrate. The SmartPeg’s magnet is activated by very low energy magnetic pulses generated by the instrument. The technique is objective, gentle, and highly repeatable

Yes, ISQ measurements can be performed on patients with a pacemaker.
As a precaution, the probe should be kept away from the chest area where the pacemaker is located, due to the magnetic pulses emitted during measurement.
There are published reports regarding pacemakers and magnetic fields for further reference.

Implant stability can be measured at different stages of treatment.
It is typically measured at implant placement to establish a baseline, and then during healing to monitor changes in stability and osseointegration. A final measurement is often taken before loading to support the decision.
Repeated measurements over time provide valuable information, as the trend in ISQ values helps guide clinical decisions.

Alcune spiegazioni possibili includono:

Riutilizzo degli SmartPeg: Gli SmartPeg sono monouso e devono essere utilizzati per eseguire una o più misurazioni in una sessione di trattamento e su un solo paziente. Riutilizzarli in modo ripetuto può provocare letture errate a causa dell’usura delle filettature degli SmartPeg in alluminio morbido.

Tipo errato di SmartPeg selezionato per l’impianto: Consultare l’elenco di riferimento degli SmartPeg alla pagina osstell.com/smartpegguide

Presenza di tessuto osseo o tessuto molle tra SmartPeg e impianto: Assicurarsi di pulire l’innesto protesico dell’impianto prima di collegare lo SmartPeg.

Interferenze elettromagnetiche: Rimuovere la fonte di interferenze elettromagnetiche.

La sonda è tenuta troppo lontana dallo SmartPeg: Tenere la sonda a una distanza di 2-4 mm dallo SmartPeg.

ISQ should always be measured in two directions, because implant stability can vary depending on the amount of surrounding bone in different directions. Measuring from two angles ensures that both the most and the least stable directions are captured.
To do this, take one measurement in the buccal-lingual direction and one in the mesial-distal direction. These two ISQ values represent the different stability directions. Sometimes the values are identical; sometimes they differ.
If the two measurements differ, always rely on the lowest ISQ value, as it reflects the weakest direction and therefore provides the most clinically relevant information about implant stability.

There are currently thousands of articles where Osstell devices were used in the study, published in scientific papers. These abstracts could be found in our searchable database under “Resources/Scientific database“.

The Osstell ISQ scale is based on outcomes from these studies, all performed using Osstell instruments and aluminium SmartPegs.

Osstell measures implant stability using Resonance Frequency Analysis (RFA). The small SmartPeg that you attach to the implant has a tiny magnet on top. When the probe sends magnetic pulses, the SmartPeg starts to vibrate – similar to a very small tuning fork.
How it works:

1. The instrument tip sends magnetic pulses
   These pulses make the SmartPeg vibrate without touching it.
2. The vibration changes depending on how stable the implant is
   – A stable implant (good bone support) makes the SmartPeg vibrate faster.
   – A less stable implant makes it vibrate slower.
3. The device converts this vibration into an ISQ value
   – Higher stability → higher frequency → higher ISQ
   – Lower stability → lower frequency → lower ISQ

It takes less than a second, and the ISQ value is shown immediately.

If no ISQ value appears, it usually means the SmartPeg’s vibration is not being detected clearly by the instrument. Several factors can cause this, and most are easy to resolve:

1. Distance to instrument is too great
   The instrument should normally be held 2–4 mm from the magnet on top of the SmartPeg. Do not touch the magnet. If no value appears, move the instrument closer until the signal is detected.

ISQ e BIC misurano aspetti diversi dell’integrazione implantare.

BIC (bone-to-implant contact, contatto osso-impianto) descrive la percentuale della superficie implantare a contatto con l’osso a livello microscopico, mentre ISQ riflette la stabilità implantare misurando la rigidità dell’interfaccia osso-impianto.

Di conseguenza, un BIC elevato non significa sempre stabilità elevata, poiché anche qualità e rigidità dell’osso svolgono un ruolo fondamentale.

Per una spiegazione più dettagliata, vedere: How ISQ correlates to torque

Il torque è una misurazione statica, effettuata una sola volta al momento del posizionamento dell’impianto, e non può essere ripetuta in seguito senza mettere a rischio l’osteointegrazione dell’impianto. Riflette l’attrito rotazionale tra la superficie dell’impianto e l’osso, anziché la stabilità laterale dell’impianto.

La misurazione della stabilità implantare con gli strumenti Osstell valuta la stabilità laterale dell’impianto. Le misurazioni sono senza contatto e possono essere ripetute nel tempo per monitorare lo sviluppo dell’osteointegrazione.

Non esiste un unico valore ISQ che determini l’idoneità al carico immediato. Oltre al valore ISQ, la decisione dipende dalla stabilità primaria, dal giudizio clinico e dai fattori di rischio specifici del paziente.

Come indicazione generale, valori ISQ più elevati indicano maggiore stabilità e valori pari o superiori a circa 70 possono supportare il carico immediato in casi appropriati.
Per indicazioni sull’interpretazione dei valori ISQ, consultare la scala ISQ Osstell.

Non esiste un unico valore ISQ che determini quando un impianto può essere caricato. La decisione dipende dalla stabilità nel tempo (l’andamento dell’ISQ), nonché dal giudizio clinico e dai fattori di rischio specifici del paziente.

Come indicazione generale, valori ISQ più elevati offrono maggiore affidabilità e valori pari o superiori a circa 70 sono spesso considerati adatti per il carico di impianti non solidarizzati. Per restauri solidarizzati possono essere accettabili valori inferiori.

Per indicazioni sull’interpretazione dei valori ISQ, consultare la scala ISQ Osstell.

ISQ (Implant Stability Quotient) è un valore numerico da 1 a 99 che descrive la stabilità implantare. Viene calcolato dalla frequenza di risonanza misurata quando lo strumento Osstell invia un impulso magnetico a uno SmartPeg collegato all’impianto, traducendola in un valore clinicamente intuitivo.

Viene calcolato dalla frequenza di risonanza misurata quando lo strumento Osstell invia un impulso magnetico a uno SmartPeg collegato all’impianto, traducendola in un valore clinicamente intuitivo.

ISQ significa Implant Stability Quotient e deriva dagli Hertz, poiché la tecnica utilizzata è l’Analisi della Frequenza di Risonanza (RFA). La scala in Hertz non è intuitiva né facile da comunicare, perciò oltre 20 anni fa è stata tradotta in una scala ISQ da 1 a 99. Oggi sappiamo che la scala correla con la micromobilità: una stabilità elevata corrisponde a > 70 ISQ, tra 60 e 69 a stabilità media e < 60 ISQ è considerata bassa stabilità.

La scala ISQ Osstell è importante perché fornisce informazioni precise sull’andamento dell’osteointegrazione, aiutando i clinici a determinare il momento ottimale per il carico protesico e a garantire un protocollo chirurgico sicuro. 4 5

Un impianto dentale osteointegrato è un impianto che si è legato all’osso circostante, fornendo una base stabile per i denti protesici e mantenendo la propria stabilità nel tempo. 1 2

Durante l’osteointegrazione, le cellule ossee crescono intorno alla superficie dell’impianto e vi si legano, passando nel tempo dalla stabilità meccanica a quella biologica. 1 3

L’osteointegrazione è la connessione diretta e funzionale tra osso vivente e superficie di un impianto. È un fattore cruciale per garantire la stabilità e il successo degli impianti dentali. 1 2

Two years.

The IDx continues to consume a small amount of power even when switched off. If the battery becomes fully depleted (0%), the stored date and time settings will be lost.
When this happens, you will be prompted to set the date and time again at start-up.

If your IDx is connected to the internet, the date and time will be set automatically.

An electromagnetic noise warning indicates the presence of an external or internal magnetic disturbance that may affect the measurement.
This can occur due to nearby electronic equipment, or if the probe is held very close to the instrument itself.

ISQ should always be measured in two directions, because implant stability can vary depending on the amount of surrounding bone in different directions. Measuring from two angles ensures that both the most and the least stable directions are captured.
To do this, take one measurement in the buccal-lingual direction and one in the mesial-distal direction. These two ISQ values represent the different stability directions. Sometimes the values are identical; sometimes they differ.
If the two measurements differ, always rely on the lowest ISQ value, as it reflects the weakest direction and therefore provides the most clinically relevant information about implant stability.

Register your IDx by following the instructions in the device or by following this link.

Osstell measures implant stability using Resonance Frequency Analysis (RFA). The small SmartPeg that you attach to the implant has a tiny magnet on top. When the probe sends magnetic pulses, the SmartPeg starts to vibrate – similar to a very small tuning fork.
How it works:

1. The instrument tip sends magnetic pulses
   These pulses make the SmartPeg vibrate without touching it.
2. The vibration changes depending on how stable the implant is
   – A stable implant (good bone support) makes the SmartPeg vibrate faster.
   – A less stable implant makes it vibrate slower.
3. The device converts this vibration into an ISQ value
   – Higher stability → higher frequency → higher ISQ
   – Lower stability → lower frequency → lower ISQ

It takes less than a second, and the ISQ value is shown immediately.

For normal use, the batteries last for at least one day but in most cases longer. It takes about 2 hours to charge the IDx from a fully discharged state.

Choose a tooth position on the touch screen and start measuring.

No. The Osstell measurement does not affect the implant. The instrument only makes the SmartPeg vibrate. The SmartPeg’s magnet is activated by very low energy magnetic pulses generated by the instrument. The technique is objective, gentle, and highly repeatable

Please note that single-use SmartPegs are disposable and cannot be autoclaved!

Yes, ISQ measurements can be performed on patients with a pacemaker.
As a precaution, the probe should be kept away from the chest area where the pacemaker is located, due to the magnetic pulses emitted during measurement.
There are published reports regarding pacemakers and magnetic fields for further reference.

To enable automatic backup of your Osstell IDx, you will be asked to create a backup code made up of 8 characters. The purpose of the backup is to reset the unit if you for some reason remove patients by mistake or lose your instrument. The code is created during the registration process and you only have to enter it once. To make sure you can access your backup at a later date, it is VERY important that you write this code down and keep it in a safe place.

Backup can also be done via USB without a code.

ISQ stands for Implant Stability Quotient and is a recalculated value derived from the resonance frequency (Hz) measured using Resonance Frequency Analysis (RFA). The scale in Hertz is non-intuitive and hard to communicate so it was translated to a scale of ISQ 1-99, more than 20 years ago. Today we know that the scale correlates to micro mobility and that high stability means > 70 ISQ, between 60-69 is medium stability and < 60 ISQ is considered as low stability.

ISQ (Implant Stability Quotient) is a numerical value from 1 to 99 that describes implant stability. It is calculated from the resonance frequency measured when the Osstell instrument sends a magnetic pulse to a SmartPeg attached to the implant, translating this into a clinically intuitive value.

There is no single ISQ value that determines when an implant can be loaded. The decision depends on the stability over time (the ISQ trend), as well as clinical judgement and patient-specific risk factors.
As a general guideline, higher ISQ values provide greater confidence, and values around 70 or above are often considered suitable for loading non-splinted implants. For splinted restorations, lower values may be acceptable.
For guidance on how to interpret ISQ values, see the Osstell ISQ Scale.

ISQ should always be measured in two directions, because implant stability can vary depending on the amount of surrounding bone in different directions. Measuring from two angles ensures that both the most and the least stable directions are captured.
To do this, take one measurement in the buccal-lingual direction and one in the mesial-distal direction. These two ISQ values represent the different stability directions. Sometimes the values are identical; sometimes they differ.
If the two measurements differ, always rely on the lowest ISQ value, as it reflects the weakest direction and therefore provides the most clinically relevant information about implant stability.

There is no single ISQ value that determines suitability for immediate loading. In addition to the ISQ value, the decision depends on primary stability, clinical judgement, and patient-specific risk factors.
As a general guide, higher ISQ values indicate greater stability, and values around 70 or above may support immediate loading in appropriate cases.
For guidance on interpreting ISQ values, see the Osstell ISQ Scale.

There are currently thousands of articles where Osstell devices were used in the study, published in scientific papers. These abstracts could be found in our searchable database under “Resources/Scientific database“.

The Osstell ISQ scale is based on outcomes from these studies, all performed using Osstell instruments and aluminium SmartPegs.

Osstell measures the lateral stability of the implant and thereby indirectly the degree of osseointegration. The results are presented as an ISQ, ranging from 1-99 ISQ, which correlates to micro mobility.

Periotest (DCA) measurements are designed for natural teeth, which are connected to the bone via the periodontal ligament. In contrast, dental implants are anchored directly to the bone without a periodontal ligament.
RFA measurements using Osstell instruments assess implant stability by measuring the stiffness of the bone–implant interface. They provide an objective and repeatable value on a more sensitive scale, supporting reliable assessment over time.

Torque is a one-time, static measurement taken at implant placement and cannot be repeated later without risking the implant’s osseointegration. It reflects the rotational friction between the implant surface and the bone, rather than the lateral stability of the implant.
Measuring implant stability with Osstell instruments assesses the lateral stability of the implant. These measurements are contact-free and can be repeated over time to monitor the development of osseointegration.

ISQ and BIC measure different aspects of implant integration.
BIC (bone-to-implant contact) describes the percentage of the implant surface in contact with bone at a microscopic level, while ISQ reflects implant stability by measuring the stiffness of the bone–implant interface.

As a result, high BIC does not always mean high stability, as bone quality and stiffness also play a key role.

For a more detailed explanation, see: How ISQ correlates to torque

Yes. The ISQ value can be affected if the SmartPeg is not mounted correctly.

For accurate measurements, the SmartPeg should be attached finger tight using the SmartPeg Mount, which corresponds to about 4–6 Ncm.

At this level, the SmartPeg has firm, stable contact with the implant, and the resulting ISQ value is consistent – typically within ±2 ISQ units.

• If the SmartPeg is not fully seated:
  The contact becomes unstable, and the ISQ value can appear artificially low, or you don’t receive any value.
• If too much force is applied:
  Overtightening does not improve accuracy. It may damage the SmartPeg threads.
  – A reusable SmartPeg may be damaged so it cannot be used again.
  – A single use or reusable SmartPeg may have its threads deformed, which can lead to inaccurate measurements during that session or, in worst case a broken SmartPeg.

In short: finger tight (4–5 Ncm) is enough to ensure stable contact and reliable ISQ readings.

If no ISQ value appears, it usually means the SmartPeg’s vibration is not being detected clearly by the instrument. Several factors can cause this, and most are easy to resolve:

1. Distance to instrument is too great
   The instrument should normally be held 2–4 mm from the magnet on top of the SmartPeg. Do not touch the magnet. If no value appears, move the instrument closer until the signal is detected.
2. Angle needs adjustment
   The magnetic field is directional, so the orientation of the instrument matters. Measurements should be taken at approximately a 45° angle relative to the top of the SmartPeg.
3. Ensure you have the correct SmartPeg Type for the specific implant

4. Soft tissue damping
   Surrounding tissue can sometimes dampen the vibration more than expected. Holding the instrument a bit closer usually compensates for this.
5. The implant platform is not clean
   Ensure the implant platform is clean and free of debris, so the SmartPeg seats properly and transmits its vibration.
6. The SmartPeg is worn or damaged
   • If you are using a reusable SmartPeg, make sure it has been inspected before use and that it is within 20 reprocessing cycles. A reusable SmartPeg that is worn out, bent, or has damaged threads will not vibrate correctly — and the instrument may not be able to pick up a reading.
   • A single‑use SmartPeg is intended for one treatment session only.
   • Ensure the SmartPeg is properly seated on the implant and that it is not in contact with surrounding tissue, as this can prevent accurate signal detection and may result in no ISQ value or an incorrect one.
7. Electromagnetic interference
   Strong electromagnetic noise sources nearby may disturb the measurement. (See the FAQ on “Electromagnetic noise” for details.)

Clinically, the lowest ISQ values typically seen are around 40.

If the stability is below 30, the implant is generally considered to have very low stability or to be loose. It may also indicate that the SmartPeg is not correctly mounted on the implant.

Very low values (below 20) are rarely seen in clinical situations and are more commonly observed in laboratory models with artificially low stability.

Implant stability can be measured at different stages of treatment.
It is typically measured at implant placement to establish a baseline, and then during healing to monitor changes in stability and osseointegration. A final measurement is often taken before loading to support the decision.
Repeated measurements over time provide valuable information, as the trend in ISQ values helps guide clinical decisions.
