PURPOSE: To investigate the clinical effect of piezosurgery combined with 45°contra-angle turbine drill in extraction of impacted mandibular wisdom teeth.
METHODS: A total of 146 patients with impacted wisdom teeth at the median mandibular level admitted from June 2022 to June 2024 were randomly divided into control group and experimental group, with 73 cases in each group. The wisdom teeth in the control group were simply removed using 45° contra-angle turbine drill, while those in the experimental group were removed using piezosurgery combined with 45° contra-angle turbine drill. The treatment outcomes, postoperative pain, limited swelling and incidence of postoperative complications of the two groups were compared.
RESULTS: There was no significant difference in operation time between the two groups(P＞0.05), and the amount of blood loss in the experimental group was significantly lower than that in the control group(P＜0.05). The visual analogue scale(VAS) of pain in the experimental group was significantly lower than that of the control group on the 1st and 3rd day after surgery(P＜0.05). Immediately, 1 day and 3 days after surgery, the serum C-reactive protein (CRP) in the experimental group was significantly lower than that in the control group (P＜0.05). The score of facial swelling degree and proportion in the experimental group were significantly lower than those in the control group (P＜0.05), the reduction rate of mouth opening degree and the proportion of mouth opening restriction in the experimental group were significantly lower than those in the control group(P＜0.05). There were no significant differences in the total incidence of postoperative complications such as tongue numbness, lower lip numbness, adjacent tooth injury, dry socket and root fracture between the two groups(P＞0.05).
CONCLUSIONS: Compared with only using 45° contra-angle turbine drill, the combination of piezosurgery for impacted mandibular wisdom teeth extraction can help reduce intraoperative bleeding, alleviate pain and swelling,improve the degree of limited mouth opening.
