涡轮机法拔除下颌阻生智齿的临床研究

目的:比较拔除中位和低位阻生智齿时,凿骨劈冠法与涡轮机去骨拔除法的优劣。方法:51例双侧中位或低位阻生齿,双侧随机分组,分别使用涡轮机去骨拔除法和传统的凿骨劈冠拔除法拔牙,对术中反应、手术时间,以及术后疼痛、术后肿胀进行对比观察和统计分析。结果:对中位阻生智齿,涡轮机去骨拔除法的手术时间和术后反应大于凿骨劈冠法(P<0.05),但对于低位阻生齿,涡轮机去骨拔除法手术时间更短、术后反应小(P<0.05)。结论:涡轮机去骨拔除法在拔除低位阻生齿时具有明显的优势,在拔除中位阻生智齿时并不比凿骨劈冠法有明显的优势。

Extraction of impacted lower mandibular wisdom teeth by turbine drill

Objective:To study the feasibility of extraction of impacted mandibular wisdom teeth using turbine drill.Methods:Fifty-one patients with impacted mandibular wisdom teeth on both sides were included.In each patient the two wisdom teeth were randomly divided into test and control groups,the tooth on one side was extracted by means of turbine drill and that on another side by dental chisel method.The operation time,postoperative swell and pain were recorded to assess the effects of the methods.Results:In the extraction of deeply impacted teeth the operation time by turbine drill was shorter(P<0.01),one and three days after operation the swell and pain were slighter(P<0.05) than those by dental chisel.In the extraction of moderately impacted teeth the results were contrary.Conclusion:Turbine drill method is superior to dental chisel method in the extraction of deeply impacted madibular wisdom teeth.
