Dental implant treatments are safe. More than 90% are successful. But that’s not good enough. Because a failed dental implant can be agonizing for everyone involved. With today’s techniques, treatment times and opportunities for patients with risk factors have improved significantly. But correctly assessing implant stability and osseointegration is still a challenge.

That’s where Osstell comes in.

Osstell helps you to objectively and non-invasively determine implant stability and to assess the progress of osseointegration – without jeopardizing the healing process.

Osstell IDx
Osstell Benifits


Our method eliminates chance. When measuring the implant stability, you will get an objective value, making the implant treatment more predictable - even for patients with risk factors.

Reduced Time

Immediate loading is becoming more and more common. Patients want results fast. With Osstell, you only wait as long as needed.

Proven Method

Backed by more than 1000 scientific studies, our method is based on RFA to determine whether or not an implant is stable enough. The result is presented as an ISQ value of 1-100. The higher the ISQ, the more stable the implant.


Osstell IDx

  • Assess implant stability and the degree of osseointegration
  • Shorten treatment time and better manage risk patients
  • Easily interpret results through intuitive color coding based on the ISQ scale
  • Enables efficient communication with patients & collaboration with colleagues
  • Extract data, share files and analyze implant and treatment data through Osstell Connect
  • Remote back-up and support
  • Share patients between multiple IDx’s

Note: In the resource page you will find all the information you need about your instrument, including set-up, usage and care.


The SmartPeg is used together with the measurement instruments Osstell IDx or Osstell ISQ. Both instruments measure the resonance frequency of a SmartPeg, when it is attached to an implant.

The SmartPegs are single patient use items. To avoid damage to the implant, the SmartPeg material is quite soft, which limits the lifetime of the threads.

The Osstell IDx Kit comes with:

Note: SmartPegs, needed when measuring on a patient, are ordered separately.

Clinical Guidelines

Osstell ISQ Scale

The Osstell ISQ Scale

ISQ, or Implant Stability Quotient, is a scale from 1 to 100 and is a measure of the stability of an implant. The ISQ scale has a non-linear correlation to micro mobility. With more than 1000 scientific references, we now know that high stability means >70 ISQ, between 60-69 is medium stability and < 60 ISQ is considered as low stability.

Technique behind Osstell

The Technique Behind Osstell

Osstell's patented technology uses Resonance Frequency Analysis (RFA) that measures the frequency with which a device vibrates. By comparing resonance frequencies, the stability of a dental implant can be determined as the resonance frequency changes with different stabilities.

ISQ & Torque

How ISQ Correlates to Torque

Torque is sometimes used to describe the stability of an implant. However, torque does not necessarily correlate to implant stability. Torque measures the rotational friction between the implant and the bone combined with the force required to cut the bone if that is the case, and the pressure force from the surrounding bone.


How ISQ correlates to BIC

BIC, or Bone to Implant Contact, is the percentage of the implant surface in contact with bone on a microscopic level.
