SmartPeg
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 SmartPeg is attached to the implant or abutment when a measurement is made. It is easy to mount and requires minimal space thanks to its small size. To avoid damage to the implant, the SmartPeg material is quite soft, which limits the lifetime of the threads.

FAQ
Can I re-use the SmartPegs?
The SmartPegs are single use items. To avoid damage to the implant, the SmartPeg material is quite soft, which limits the lifetime of the threads. So the SmartPeg cannot be reused for two reasons:
First, the magnet cannot stand the heat of an autoclave, it will be affected and discolored. Second, the threads are made weak not to jeopardize the inner threads in the implant. Reusing the SmartPeg might wear out the threads and give misleading ISQ values.
Is the ISQ-value sensitive to how hard the SmartPeg is tightened?
The SmartPeg should be tightened with 4-5 Ncm, which means “finger tight”, using the SmartPeg Mount. It is enough with firm contact between the SmartPeg and the implant. The difference in ISQ value will then stay within 2 ISQ units. (If the SmartPeg is tightened too loosely, the ISQ-value will be lower.) If the SmartPeg is over-tightened, there is a risk that the SmartPeg threads will be damaged.

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.
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.
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.
