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.

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.

Prior to the first clinical use, and after each use the reusable products must be cleaned, disinfected and sterilized according to the instructions in the quickguide that is found here: Osstell/ifu

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.

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.

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.

1. Activate the Osstell Beacon by picking it up. The instrument will start-up and after showing the battery status, the instrument will be ready for measurement in the BL (Buccal – Lingual) direction, which is prompted in the upper display as well as optimal angle towards the Smartpeg.

2. Place a barrier sleeve over the Osstell beacon instrument.

3. Place the SmartPeg into the SmartPeg Mount. The SmartPeg is magnetic, and the SmartPeg Mount will hold the SmartPeg. See fig 2. Attach the SmartPeg to the implant or abutment by screwing the SmartPeg Mount using finger force of approximately 4-6 Ncm. Do not over-tighten, to avoid damaging the SmartPeg threads.

4. Hold the instrument tip close (2-4mm) to the top of the SmartPeg without touching it. Sometimes, you will need to go as close as 1 mm. An audible sound indicates when measurement has started, and measured data will be shown in the upper display combined with a colored light indication below the tip.

5. Bring the instrument out of the mouth to clearly read the ISQ value and the colored indication. The measured ISQ values will be displayed in the upper display for a couple of seconds and then switch to be ready for measurement in mesial-distal direction.

6. Repeat step 4 and the sequence starts over and the Osstell Beacon is ready for measurement in the BL (Buccal- Lingual) direction again.

7. When all measurements are performed, remove the SmartPeg by using the SmartPeg Mount. The instrument is automatically turned off after 60 seconds of inactivity.

考えられる原因を以下に挙げます。

SmartPegが再使用されている： SmartPegは使い捨てであり、1回の治療セッションで1人の患者に対して、1回または複数回の測定にのみ使用して下さい。繰り返し再使用すると、軟らかいアルミニウム製SmartPegのねじ部の摩耗により、誤った測定値が出る可能性があります。

インプラントに対して誤った種類のSmartPegが選択されている： SmartPegの参照リスト（osstell.com/smartpegguide）をご覧下さい。

SmartPegとインプラントの間に骨または軟組織が介在している： SmartPegを装着する前に、必ずインプラントの補綴接続部を清掃して下さい。

電磁干渉： 電磁干渉の原因を取り除いて下さい。

プローブがSmartPegから離れすぎている： プローブをSmartPegから2～4mm離して保持して下さい。

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.

The red, yellow and green color indicates if the measured ISQ value corresponds to a low, medium or high implant stability according to the ISQ scale guidance, click here for more information.

After 60 seconds of no motion, the Osstell Beacon will turn off automatically.

Possible explanations include:

Re-Used SmartPeg: The SmartPegs are disposable and should only be used for one or multiple measurement at one treatment session, for a single patient only. Repeated re-use may result in false readings due to wear and tear of the soft aluminum SmartPeg threads.

Wrong SmartPeg type selected for the implant: See SmartPeg reference list, osstell.com/smartpegguide

Bone or soft tissue in between SmartPeg and Implant: Make sure to clean the Implant prosthetic connection before attaching the SmartPeg.

Electromagnetic interference: Remove the source of electromagnetic interference.

Probe is held too far away from the SmartPeg: Hold the probe 2-4 mm away from the SmartPeg.

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.

ISQ値が表示されない場合、多くは、インスツルメントがSmartPegの振動を正しく検出できていません。その原因はいくつか考えられますが、ほとんどは簡単に対処できます。

1. インスツルメントがSmartPegから離れすぎている
   インスツルメントは通常、SmartPeg上部の磁石から2～4 mmの位置に保持する必要があります。磁石には接触しないようにして下さい。ISQ値が表示されない場合は、信号が検出されるまでインスツルメントを少しずつ近づけて下さい。
2. インスツルメントの角度を調整する必要がある
   磁場には方向性があるため、インスツルメントの向きが測定に影響します。SmartPegの上部に対して約45°の角度で測定して下さい。
3. 使用しているSmartPegのタイプがインプラントに適合していることを確認する
   以下のリンクを使用して、適切なSmartPegのタイプを確認して下さい：適切なSmartPegを選択
4. 軟組織による振動の減衰
   周囲の軟組織によって、SmartPegの振動が想定以上に減衰することがあります。この状態は通常、インスツルメントを少し近づけることで改善します。
5. インプラントプラットフォームが清潔ではない
   SmartPegが正しく装着され、振動が適切に伝達されるよう、インプラントプラットフォームが清潔で、異物がないことを確認して下さい。
6. SmartPegが摩耗または損傷している
   • 再使用可能SmartPegをご使用の場合は、使用前に点検を行い、前処理サイクルが20回以内であることを確認して下さい。再使用可能SmartPegが摩耗、変形している場合、またはそのねじ部が損傷している場合は正常に振動せず、インスツルメントがISQ値を測定できないことがあります。
   • 単回使用SmartPegは、1回の治療でのみ使用して下さい。
   • SmartPegがインプラントに正しく装着され、周囲の軟組織に接触していないことを確認して下さい。軟組織に接触していると、信号を正しく検出できず、ISQ値が表示されない、または正確な値が得られないことがあります。
7. 電磁干渉
   近くに強い電磁ノイズ源があると、測定に影響を及ぼすことがあります。（詳しくは「電磁ノイズ」のFAQをご覧下さい。）

いいえ。Osstellによる測定がインプラントに影響を与えることはありません。インスツルメントはSmartPegを振動させるだけです。SmartPegの磁石は、インスツルメントが発生させる微弱な磁気パルスによって作動します。この測定方法は客観的で、インプラントへの負荷が少なく、再現性に優れています。

はい。患者がペースメーカーを装着していても、ISQ測定を行うことができます。
ただし、測定中はインスツルメントから磁気パルスが発生するため、念のために、プローブはペースメーカーが埋め込まれている胸部付近に近づけないで下さい。
ペースメーカーと磁場との関係については、公表されている文献もありますので、必要に応じてご参照下さい。

インプラントの安定性は、治療のさまざまな段階で測定できます。
通常は、ベースラインを取得するためにインプラント埋入時に測定し、その後は治癒期間中に安定性やオッセオインテグレーションの変化をモニタリングするために測定します。また、一般的には、荷重開始前に最後の測定を行い、荷重開始の判断に活用します。
経時的に繰り返し測定することで、ISQ値の推移を把握でき、臨床判断に役立つ有用な情報が得られます。

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.

You can find the serial number on the back of your instrument.

考えられる原因を以下に挙げます。

SmartPegが再使用されている： SmartPegは使い捨てであり、1回の治療セッションで1人の患者に対して、1回または複数回の測定にのみ使用して下さい。繰り返し再使用すると、軟らかいアルミニウム製SmartPegのねじ部の摩耗により、誤った測定値が出る可能性があります。

インプラントに対して誤った種類のSmartPegが選択されている： SmartPegの参照リスト（osstell.com/smartpegguide）をご覧下さい。

SmartPegとインプラントの間に骨または軟組織が介在している： SmartPegを装着する前に、必ずインプラントの補綴接続部を清掃して下さい。

電磁干渉： 電磁干渉の原因を取り除いて下さい。

プローブがSmartPegから離れすぎている： プローブをSmartPegから2～4mm離して保持して下さい。

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.

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.

ISQ値が表示されない場合、多くは、インスツルメントがSmartPegの振動を正しく検出できていません。その原因はいくつか考えられますが、ほとんどは簡単に対処できます。

1. インスツルメントがSmartPegから離れすぎている
   インスツルメントは通常、SmartPeg上部の磁石から2～4 mmの位置に保持する必要があります。磁石には接触しないようにして下さい。ISQ値が表示されない場合は、信号が検出されるまでインスツルメントを少しずつ近づけて下さい。
2. インスツルメントの角度を調整する必要がある
   磁場には方向性があるため、インスツルメントの向きが測定に影響します。SmartPegの上部に対して約45°の角度で測定して下さい。
3. 使用しているSmartPegのタイプがインプラントに適合していることを確認する
   以下のリンクを使用して、適切なSmartPegのタイプを確認して下さい：適切なSmartPegを選択
4. 軟組織による振動の減衰
   周囲の軟組織によって、SmartPegの振動が想定以上に減衰することがあります。この状態は通常、インスツルメントを少し近づけることで改善します。
5. インプラントプラットフォームが清潔ではない
   SmartPegが正しく装着され、振動が適切に伝達されるよう、インプラントプラットフォームが清潔で、異物がないことを確認して下さい。
6. SmartPegが摩耗または損傷している
   • 再使用可能SmartPegをご使用の場合は、使用前に点検を行い、前処理サイクルが20回以内であることを確認して下さい。再使用可能SmartPegが摩耗、変形している場合、またはそのねじ部が損傷している場合は正常に振動せず、インスツルメントがISQ値を測定できないことがあります。
   • 単回使用SmartPegは、1回の治療でのみ使用して下さい。
   • SmartPegがインプラントに正しく装着され、周囲の軟組織に接触していないことを確認して下さい。軟組織に接触していると、信号を正しく検出できず、ISQ値が表示されない、または正確な値が得られないことがあります。
7. 電磁干渉
   近くに強い電磁ノイズ源があると、測定に影響を及ぼすことがあります。（詳しくは「電磁ノイズ」のFAQをご覧下さい。）

いいえ。Osstellによる測定がインプラントに影響を与えることはありません。インスツルメントはSmartPegを振動させるだけです。SmartPegの磁石は、インスツルメントが発生させる微弱な磁気パルスによって作動します。この測定方法は客観的で、インプラントへの負荷が少なく、再現性に優れています。

はい。患者がペースメーカーを装着していても、ISQ測定を行うことができます。
ただし、測定中はインスツルメントから磁気パルスが発生するため、念のために、プローブはペースメーカーが埋め込まれている胸部付近に近づけないで下さい。
ペースメーカーと磁場との関係については、公表されている文献もありますので、必要に応じてご参照下さい。

インプラントの安定性は、治療のさまざまな段階で測定できます。
通常は、ベースラインを取得するためにインプラント埋入時に測定し、その後は治癒期間中に安定性やオッセオインテグレーションの変化をモニタリングするために測定します。また、一般的には、荷重開始前に最後の測定を行い、荷重開始の判断に活用します。
経時的に繰り返し測定することで、ISQ値の推移を把握でき、臨床判断に役立つ有用な情報が得られます。

• Your registration code is now displayed on your Osstell IDx.

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.

Yes, OsstellConnect is accessible via iPhone, iPad, Mac or PC.

Have you registered your device? You can only use the Osstell IDx for a limited time without registration.

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!

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 (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.

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.

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.

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.

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.
