高速涡轮机去冠法在下颌近中阻生智齿拔除中的临床应用

目的:通过比较微创拔牙刀结合高速涡轮机去冠拔牙法与传统拔牙器械拔牙法拔除下颌近中阻生智齿的临床应用效果,寻找更合理的阻生齿拔除的方案。方法:选择临床需要拔除的下颌Ⅱ类、中位、近中阻生智齿60例,参照随机数字表按完全随机设计分为2组,每组30例,分别用original Luxato微创拔牙刀结合高速涡轮机去冠和传统拔牙器械拔除患牙,采用生理测试及投射测试比较二者的畏惧率,统计手术时间及术后患者张口度、肿胀度、疼痛、满意度、拔牙窝完整性,比较2组手术效果。结果:微创拔牙刀结合高速涡轮机去冠组患者的畏惧率明显低于传统拔牙组,手术效果明显优于传统组,二者的差异具有统计学意义(P<0.05)。结论:微创拔牙刀结合高速涡轮机去冠拔除下颌近中阻生智齿具有临床使用价值。

Decrownation of Impacted Wisdom Teeth by High-Speed Air Turbine Drill

Objective： To evaluate the efficacy on the exodontia of mandibular medial impacted wisdom tooth through the combination of minimally invasive extraction knife and high-speed turbine drill. Methods： 60 cases of medial impacted wisdom teeth were randomly and equally divided into two groups： traditional extraction group and high-speed air turbine drill extraction group. The fear rate and effects of extraction were assessed. Results： In high-speed air turbine drill extraction group, the fear rate was significantly lower than those in traditional extraction group, while the effects of drill extraction group was significantly better than those of traditional extraction group. Differences between the two groups were statistically significant （P〈0.05）. Conclusions： Minimally invasive extraction knife with high-speed turbine extraction has clinical value in mandibular medial impacted wisdom teeth extraction.
