This prospective study compared the stability of implants placed using piezoelectric surgery (piezo group) and those placed using conventional rotary drills (bur group) during the first 90 days postoperatively. Teeth in the posterior maxillary regions of twenty-one patients were randomly assigned to two groups. The implant stability quotient (ISQ) was measured at days 0, 7, 14, 21, 28, 42, 56 and 90 postoperatively. Twenty eight out of 29 implants were successfully integrated at day 90 (one implant in the test group was lost). Although both groups showed a significant overall increase in implant stability with time (p< 0.0001) and a high final mean ISQ value, no statistically significant difference in stability was seen between groups. The bur group showed greater variance in ISQ values than the piezo group (p< 0.001) at all time points. Long-term studies with larger samples are needed to investigate the bone response to the use of piezoelectric surgery for implant preparation.
