Standard Drilling Versus Ultrasonic Implant Site Preparation: A Clinical Study at 4 Weeks After Insertion of Conical Implants.

OBJECTIVE: Clinically evaluate implants placed after ultrasonic implant site preparation (UISP) and standard drilling (SD).

MATERIALS AND METHODS: Ten patients received 21 implants placed using UISP (n = 11) or SD (n = 10). Bone quality was hand assessed and final insertion torque (IT), resonance frequency analysis (ISQ) at baseline and ISQ, and removal torque values (RTV) at 4 weeks were recorded and compared.

RESULTS: Mean IT values were 70.91 and 72.40 N/cm in UISP and SD groups, respectively, and were not statistically different. IT significantly correlated to bone quality. Mean ISQ values at baseline and 4 weeks were not significantly different and were 74.72 and 74.73 for UISP and 76.70 and 73.20 for SD, respectively. Mean ISQ at baseline significantly correlated to IT values and bone quality in both groups. Mean RTV values in both UISP (51.32 N/cm) and SD (53.1 N/cm) were not significantly different but significantly correlated to IT values. All implants achieved osseointegration and were restored.

CONCLUSION: Implant placement after ultrasonic preparation can be considered a predictable technique leading to clinical and biological responses similar to SD 4 weeks after insertion.
