Abstract

Clinical examinations to monitor the osseointegration process were carried out using a new tool, the Low Resonance Frequency Analyzer (LRFA), designed to overcome the deficiencies of the Resonance Frequency Analyzer (RFA). The LRFA consists of two main elements: an accelerometer sensor as a vibration detector and a basic micro-system for controlling accelerometer sensor data, which is then forwarded to the computer. We compared osseointegration in dental implants using a RFA and a LRFA to determine if the LRFA accurately detected osseointegration. Submerged dental implants, obtained from 20 patients, were subjected to RFA and LRFA examinations. We evaluated osseointegration upon placement and after the third months. Upon placement, the mean Implant Stability Quotient (ISQ) obtained with RFA was 59.05 ± 3.72. It increased to 69.25 ± 2.77 at three months. Using LRFA, the mean ISQ was 0.06 ± 0.01 upon placement and increased to 110.11 ± 0.01 at three months. Both devices measured osseointegration accurately. RFA and LRFA are equivalent methods for measuring dental implant stability at three months post-placement.
