摘要

Aim

To evaluate the efficacy of piezosurgery compared to rotary drilling in implant placement.

Objectives

To compare implant stability, postoperative pain, swelling, and surgical duration between conventional drills and piezoelectric inserts.

Methods

Twenty-four patients with bilaterally edentulous areas (48 sites) participated in a split-mouth study design, where each patient received implants using both the conventional and piezoelectric methods. Implant stability was measured using resonance frequency analysis (RFA) immediately post-placement (time 1) and at 1 (time 2), 2 (time 3), and 4 months (time 4) postoperatively. Postoperative pain via visual analogue scale and swelling were recorded, alongside procedural duration.

Results

Significantly higher mean Implant stability quotient (ISQ) scores were observed in the Piezosurgery group at day 1 and 1 month (p = 0.001), with no significant difference at 2 and 4 months when compared to control group (p > 0.05). The Conventional group reported higher VAS scores on days 1, 3, and 5, with no difference on day 7, whereas the Piezosurgery group showed lower swelling scores on days 1 and 3. Surgical duration was significantly longer in the Piezosurgery group (p < 0.05).

Conclusion

Piezosurgery enhances initial implant stability and reduces postoperative discomfort, with comparable long-term outcomes to conventional drilling. However, the small sample size is a limitation and further studies with larger cohorts are recommended to validate these findings.
