Resonance frequency analysis (RFA) is a reliable and reproducible method to measure implant stability. In this clinical study, stability of tapered implants is measured at the time of surgery (immediate stability) and after a 2 or 3 month healing period. Immediate stability for the maxillary and mandibular implants is increased when compared with previously published data. Furthermore stability is improved after the healing period. The surgical technique, the tapered shape of the implants and the high insertion torques seem to allow these favorable results.
