反角高速涡轮机拔除低位下颌阻生齿的效果观察

Contra-angle High Speed Turbine Handpiece in the Extraction of Impacted Mandibular Third Molars

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。

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.
