20 years of experience with resonance frequency analysis : 20 Jahre Erfahrung mit der Resonanzfrequenzanalyse

• Resonance frequency analysis (RFA) was developed by Meredith and co-workers some 20 years ago and is today known as the Osstell technique. It can be used to measure implant stability in Implant Stability Quotients (ISQ) from 1 ISQ (lowest stability) to 100 ISQ (highest stability). The underlying RFA measurements in Hz translated into ISQ units evaluates implant stability in bending as a function of interface stiffness. ISQ measurements reflect local bone density and are influenced by implant placement technique, healing time and exposed implant height above the alveolar crest. It seems like implants with low and/or falling ISQ values pose an increased risk for failure compared with implants with high and/or increasing values. The Osstell technique can be used as one additional parameter to support decision-making during implant treatment and follow-up.
