Background: The aim of this study was to compare the postoperative period and healing of 2 methods used for simple tooth extraction: traditional and ultrasonic bone surgery. The clinical healing of the sockets and psychologic acceptance of the ultrasonic bone surgery were also evaluated.
Methods: Two hundred patients requiring bilateral maxillary or mandibular extractions were enrolled. The extractions of the 2 teeth were performed in the same surgical session. The extraction on 1 side was performed using traditional surgery (control site), whereas ultrasonic surgery was used on the other side (test site). The patients were clinically screened at 1, 7, 14, and 21 days.
Results: A total of 200 patients (115 women and 85 men), with a mean age of 54.8 years (range, 40-65 y), provided 400 extraction sites. The time required to perform the tooth extractions was longer at the test site than at the control site, although this difference did not reach statistical significance.
Conclusions: The piezoelectric extraction technique also provided the best surgical healing results, as evidenced by the integrity of the alveolar walls and surrounding soft tissues. In addition, the patients responded positively to ultrasonic surgery and preferred it to traditional surgery for both the surgical and postsurgical phases.
Clinical implication: Our preliminary study showed that Piezosurgery is an excellent tool for reducing the risk for complications and for improving the clinical healing and postoperative period in particular. The use of ultrasound reduces trauma to the adjacent bone and soft tissues during the tooth extraction.
