Comparison between Magneto-Dynamic, Piezoelectric, and Conventional Surgery for Dental Extractions: A Pilot Study

This pilot split-mouth study aimed to evaluate and compare early postoperative discomfort and wound healing outcomes in post-extraction sockets after dental extraction performed with a Magnetic Mallet (MM), piezosurgery, and conventional instruments (EudraCT 2022-003135-25). Twenty-two patients requiring the extraction of three non-adjacent teeth were included. Each tooth was randomly assigned to a specific treatment (control, MM, or piezosurgery). Outcome measures were the severity of symptoms after surgery, wound healing assessed at the 10-days follow-up visit, and the time taken to complete each procedure (excluding suturing). Two-way ANOVA and Tukey's multiple comparisons tests were performed to evaluate eventual differences between groups. There were no statistically significant differences between the compared methods in postoperative pain and healing, and no additional complications were reported. MM required significantly less time to perform a tooth extraction, followed by conventional instruments and piezosurgery, in increasing order (p < 0.05). Overall, the present findings suggest the use of MM and piezosurgery as valid options for dental extractions. Further randomized controlled studies are needed to confirm and extend this study's results, facilitating the selection of the optimal method for an individual patient depending on the patient's needs and preferences.
