Resonance Frequency Analysis
Encyclopedia
Resonance Frequency Analysis (RFA) is a method used to determine stability (the level of osseointegration) in dental implant
s. The stability is presented as an Implant stability quotient
(ISQ) value. The higher the ISQ value the higher the stability.
When used to determine dental implant stability with an implant stability meter, a probe emits magnetic pulses to a small magnet at the top of an abutment which is attached to the implant. The abutment starts to vibrate, the probe listens to the tone and translates it to an ISQ value.
Dental implant
A dental implant is a "root" device, usually made of titanium, used in dentistry to support restorations that resemble a tooth or group of teeth to replace missing teeth....

Implant stability quotient
The Implant Stability Quotient is a scale that indicates the level of stability and osseointegration in dental implants. The scale ranges from 1 to 100 and is measured by implant stability meters instruments using RFA technique. The acceptable stability range lies between 55-85 ISQ. Higher values...
