Clinical guidelines

Osstell uses Resonance Frequency Analysis to determine implant stability. The result is presented as an ISQ value of 1-100. The higher the ISQ, the more stable the implant. Measure at implant placement for a baseline reading and again before final restoration.

The Osstell ISQ Scale

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.

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.
