摘要： 目的：观察反角高速涡轮机在下颌低位阻生智齿拔除中的临床效果。方法：将 194例下颌阻生智齿患者随机分为涡轮机组（107例）和对照组（87例）。涡轮机组采用反角高速涡轮机拔除低位下颌阻生智齿，对照组采用传统去骨凿以及劈开凿劈冠法拔除。比较两组方法术后情况。结果：涡轮机组的拔牙时间与对照组比较差异无统计学意义(P>0.05)，涡轮机组术后肿胀程度、张口受限情况、术后疼痛程度均小于对照组，差异有统计学意义(P<0.05)。结论：使用反角高速手机拔除下颌低位阻生智齿，操作简便，相对于传统劈冠法，术后反应较轻，减轻了患者的痛苦，值得推广。

Abstract: Objective: To discuss the clinical efficacy of contra-angle high speed turbine handpiece in the extraction of impacted mandibular third molar. Methods: Extraction of 194 impacted mandibular wisdom teeth were randomly divided into two groups: in experimental group (107 cases), mandibular impacted wisdom teeth were extracted by contra-angle high speed turbine handpiece, and in control group (87 cases), traditional chisels were used. The postoperative situations between two groups were compared. Results: The time of extraction in two groups were similar(P>0.05). The postoperative swelling, limited mouth opening, postoperative pain levels of experimental group were lower than in the control group, the difference was statistically significant (P<0.05). Conclusion: High speed contra-angle turbine handpiece in the extraction of impacted mandibular third molar are more effective and convenient.
