Intraoperative procedures The surgical procedures followed asepsis guidelines and were performed under lo- cal anesthetic. A #15c scalpel blade was used to make an incision along the bone crest and, subsequently, afull mucoperio- stealflapwasraised.Thesurgicalguidewas inserted and bone drilling performed fol- lowing the manufacturer’s recommenda- tions. Afterpreparation of the surgical socket, aNeodentMorsetaperconnectionimplant was placed. It was initially placed using an electric motor and finalized with a manual torque wrench.The final placementtorque was recorded for subsequent comparative analysis.Uponcompletionofimplantplace- ment,aspecifictransducerwasfixedinside the implant (Fig. 1a) and, subsequently, the implantresonancefrequencywasmeasured (Fig. 1b) using the Osstell device. The im- plant was then torqued to a screwed abut- ment and, inturn, a specifictransducerwas set inside the abutment (Fig. 2a). At this point, the resonant frequency of the abut- mentswasmeasuredusingthesameequip- ment (Fig. 2b). Theresonancefrequencies,bothfromthe implant and the abutment, were taken from the buccal, mesial, distal and lingual aspects, and a mean value was obtained for each region. After the last measure- ment, an abutment protection cylinderor temporaryrestoration was placed andthe flap sutured. Statistical analysis The placement torque and stability were analyzed separately for each implant and Fig.1a Fig.1b Fig.2a Fig.2b Article_Saletti_00-00.qxp_Layout 1 02.03.16 20:53 Seite 2 Article_Saletti_00-00.qxp_Layout 102.03.1620:53 Seite 2
