ABSTRACT
Over the last decades, oral rehabilitation resorting to implants became a current practice as a result of high success rates reported in literature. OsstellTM device for Resonance-Frequency Analysis (RFA) provides a noninvasive and objective measurement of implant stability that enables the monitoring of the implant’s stability over time. The main aim of this study is to monitor the implant stability during surgery and the placement of the oral rehabilitation and to discuss the cases where variation was high. The sample consists of 146 rehabilitated implants. The stability was defined in units of ISQ (Implant Stability Quotient). 41% of the large variations are due to the use of biomaterials, using immediate loading or doing extractions on the same session and location of the implant surgery. The measurements of the ISQ with OsstellTM instrument proved to be a useful clinical tool for predicting the degree of osseointegration after the implant placement and assessing the stability during the rehabilitation treatment.
