Objective To explore the effect of minimally invasive painless tooth extraction technique combining painless anesthesia instrument (single tooth anesthesia, STA) and ultrasonic bone surgery in surgery. Methods Selected 150 patients from October 2021 to April 2023, divided into control group and study group by random control group, 50 patients underwent traditional local anesthesia and turbine drilling method for impacted wisdom teeth. The study group, 100 patients underwent STA painless anesthesia with minimally invasive removal, comparing the two groups of patients within 2 hours and 24 hours after surgery, incidence of adverse reactions and patient satisfaction. Results The VAS pain scores at 2 hours and 24 hours were significantly lower than the study group, statistically significant (P <0.05); the incidence of postoperative adverse effects was significantly lower than the study group, the difference was statistically significant (P <0.05); the patient satisfaction was significantly higher than the control group (P <0.05). Conclusion The minimally invasive painless tooth extraction technique combining STA and ultrasound bone knife has significant clinical effect in the removal of mandibular impacted wisdom teeth, which can effectively reduce the pain degree of patients and the incidence of postoperative adverse reactions, and improve the satisfaction of patients, which is worthy of clinical application.
