Changes in implant stability using different site preparation techniques: twist drills versus PIEZOSURGERY®. A single-blinded, randomized, controlled clinical trial.

Purpose: The objective of the present investigation was to longitudinally monitor stability changes of implants inserted using traditional rotary instruments or piezoelectric inserts, and to follow their variations during the first 90 days of healing.
