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

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 record, 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.

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 probe 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):

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.

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.

Yes, ISQ measurements with Osstell’s instruments 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. For example, this report.

Measure at implant placement and again before the final restoration to monitor the development of osseointegration. If the ISQ value is not high enough it is advised to add time and remeasure before proceeding with the prosthetic rehabilitation of the implant.

   • 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 with Osstell’s instruments 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. For example, this report.

Measure at implant placement and again before the final restoration to monitor the development of osseointegration. If the ISQ value is not high enough it is advised to add time and remeasure before proceeding with the prosthetic rehabilitation of the implant.

A escala ISQ da Osstell é importante porque fornece informações precisas sobre o progresso da osseointegração, ajudando os médicos a determinar o momento ideal para a carga protética e garantindo um protocolo cirúrgico seguro. 4 5

Um implante dentário osseointegrado é um implante que se ligou ao osso circundante, proporcionando uma base estável para dentes protéticos que permanecem seguras ao longo do tempo. 1 2

Durante a osteointegração, as células ósseas crescem ao redor da superfície do implante e se ligam a ela, fazendo a transição da estabilidade mecânica para a estabilidade biológica ao longo do tempo. 1 3

A osseointegração é a conexão direta e funcional entre o osso vivo e a superfície de um implante. É um fator crítico para garantir a estabilidade e o sucesso dos implantes dentários. 1 2

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.

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 BIC – Osstell®

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 record, 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.

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.

An electromagnetic noise warning indicates the presence of an external alternating magnetic field in the environment. This can occasionally be caused by nearby electronic equipment.

If the probe is very close to the instrument (within a few centimetres), the instrument itself may trigger the warning.

If the warning appears when measuring a SmartPeg, possible causes include:

• High implant stability: A very strong signal (e.g. in highly stable implants or models without soft tissue) can trigger the warning. Try increasing the distance between the probe and the SmartPeg slightly.
• Improperly mounted SmartPeg: If the SmartPeg is not properly attached, it may cause interference. In such cases, check the fit and replace the SmartPeg if the threads are damaged.

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.

Measure at implant placement and again before the final restoration to monitor the development of osseointegration. If the ISQ value is not high enough it is advised to add time and remeasure before proceeding with the prosthetic rehabilitation of the implant.

ISQ means Implant Stability Quotient and derives from Herz since the technique we use is Resonance Frequency Analysis (RFA). The scale in Herz 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.

An ISQ value (Implant Stability Quotient) is a numerical measurement of implant stability on a scale from 1 to 99, where higher values indicate greater stability.
The scale is non-linear, meaning that a difference in ISQ can represent a significant change in stability – for example, the increase in stability from ISQ 60 to 70 is close to 50%.
ISQ is used to assess and monitor implant stability over time, supporting clinical decision-making throughout treatment.

You can read more about the ISQ scale here.

ISQ is one parameter used to support decisions on when to load an implant, and should always be considered together with the clinical situation.
As a general guideline, ISQ values above 70 indicate high stability and may support earlier loading, while lower values may require a more cautious approach and follow-up measurements.
Monitoring ISQ over time is important, as stable or increasing values indicate favourable healing and osseointegration.

You can read more about the ISQ scale here.

SmartPegs can be used for several implants in one patient session, but never reused later.
They can be used for multiple implants during the same patient session, but not reused later. The magnet cannot withstand autoclaving, and the soft threads are designed to protect the implant’s internal threads. Reusing a SmartPeg may damage the implant or give inaccurate ISQ values.

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.

The decision to proceed with immediate loading should not be based on the ISQ value alone.

While a high ISQ indicates good primary stability – which is an important factor for successful immediate loading – other clinical parameters must also be considered, such as bone quality, implant type, and patient-specific factors.

As a general guideline, ISQ values above 70 indicate high stability and may support immediate loading. Many studies report good outcomes in such cases, particularly when stability remains high throughout healing.

Monitoring the ISQ trend over time is also important, as stable or increasing values indicate favourable conditions for osseointegration and loading.

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

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.

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 probe 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.

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 (Osstell ISQ) uses a non-contact, non-invasive technique to measure implant stability. It provides an objective and repeatable value on a more sensitive scale, supporting reliable assessment over time.

Read more here: Do different methods for measuring implant stability give the same answer? – Osstell®

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.

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.)

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.

Yes, ISQ measurements with Osstell’s instruments 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.
