Observational Study on the Preparation of the Implant Site With Piezosurgery vs Drill: Comparison Between the Two Methods in Terms of Post-operative Pain, Surgical Times and Operational Advantages

"The surgery was always performed by the same operator (M.M.) to reduce the bias of the study. Loco-regional anesthesia was performed with Mepivacaine hydrochloride with 1:100000 adrenaline.~For the preparation of implant sites using traditional methods, the drills were used following manufacturer's protocol by the implant system in use (WINSIX®- BioSAF IN s.r.l, Trezzano Rosa, Trezzano Rosa, Milano - Italy).~For the preparation of sites was used ultrasonic device, (Surgysonic II, Esacrom S.r.l., Imola, Italy). For the final preparation and insertion of implants, 5-6 ultrasound inserts were used in sequence as follows: tip-shape 1st insert (ES012X) and 2nd insert (ES052XG), crown-shape 3rd insert (ES040), 4th insert (ES041), 5 ° insert (ES043) and 6th insert (ES044).~The implant insertion was performed with a maximum torque of 35 Ncm. Finally, the cap screws were positioned, and the flaps were sutured in Vycril® 3.0."
