Abstract

Abstract: Objective: To analyze the clinical effect of piezosurgery combined with 45 degree contra-angle turbo drill in the extraction of mandibular impacted wisdom teeth. Methods: Four hundred and seventy patients with mandibular impacted wisdom teeth were randomly divided into the experimental group and the control group. Two hundred and fifty-one patients with mandibular impacted wisdom teeth extracted by piezosurgery combined with 45 degree contra-angle turbo drill were listed as the experimental group. Two hundred and nineteen patients with mandibular impacted wisdom teeth extracted by 45 degree contra-angle turbo drill were listed as control group. The complications of intraoperative and postoperative between the two groups were compared. Results: There was no significant difference in the extraction time between experimental group and control group. The incidence of intraoperative and postoperative complications in the experimental group was lower than that in the control group (P<0.05). Conclusion: Piezosurgery combined with 45 degree contra-angle turbo drill in the extraction of mandibular impacted wisdom teeth can reduce the incidence of intraoperative and postoperative complications.

Key words: impacted tooth, tooth extraction, piezosurgery, contra-angle of turbo drill
