Abstract：Objective To compare and observe the effect and safety of minimally invasive extraction and traditional extraction in the extraction of impacted mandibular wisdom teeth,so as to provide reference for the selection of surgical treatment Methods in the future.Methods A total of 5000 patients with unilateral impacted mandibular wisdom teeth in the Department of Stomatology of our hospital and the First People′s Hospital of Huizhou City from January 2016 to April 2019 were selected as observation samples.They were randomly divided into the control group and the observation group,with 2500 cases in each group.The control group was treated with traditional tooth extraction (chisel and crown splitting),and the observation group was treated with high-speed turbines and long splitting,minimally invasive tooth extraction combined with drill and minimally invasive tooth extraction knife.The operation time of the two groups was compred,and visual analogue scale score was used to evaluate the degree of pain after operation in the two groups.The complications of the two groups were recorded the occurrence of perioperative complications.Results The operation time of the observation group was(17.75±3.53)min,which was significantly shorter than (33.16±6.24)min of the control group,with statistical significance (P＜0.05).The pain degree of the observation group was significantly better than that of the control group,with statistical significance (P＜0.05).The total incidence of perioperative complications in the observation group was 19.16%,which was significantly lower than that in the control group(50.32%),with statistical significance(P＜0.05).Conclusion Minimally invasive extraction of impacted mandibular wisdom teeth has shorter operation time,with less pain,lower incidence of perioperative complications and high safety.It can be used as the preferred method in clinical promotion and application.
