二次分冠"抽屉"式拔除水平阻生齿临床效果评价

目的观察采用二次分冠“抽屉”式拔除法拔除阻生齿的临床效果。方法观察实验组60只阻生齿用二次分冠法拔除效果,与对照组60只阻生齿常规翻瓣法拔除比较。结果二次分冠法拔除阻生齿成功率为95%。实验组手术时间明显比对照组手术时间短(P<0.05)。两组患者局部肿胀、疼痛和张口受限程度存在显著性差异(P<0.05)。结论采用二次分冠法拔除阻生齿,手术简便,时间短,术后不良反应少。

Extraction of impacted mandibular third molars with two times dividing crown

Objective:To evaluate the clinical effect of dental extraction Method with two times dividing crown in extraction of impacted mandibular third molars.Methods:120 impacted mandibular third molars included in this study were randomly assigned to two groups;one(test group) extracted by two times dividing crown,and the other(control group)by routine method.Then the clinical reaction-swelling,ache,and opening of mouth were observed.Results: The data showed that the duration of extraction and degree of clinical poor reaction had significant difference in two groups(P<0.05).Conclusion: Method with two times dividing crown applying in extraction of impacted teeth can efficiently cut the duration of extraction,mitigate swelling and pain,lighten limitation of mouth opening,which was recommendable.
