问题 单项选择题 A2型题

患者,男,25岁,行左下第三磨牙拔除术,在拔除下颌智齿的方法中,以下操作方法中正确的是()

A.远中切口应偏舌侧

B.颊侧切口与远中切口的末端成90°角向下

C.黏骨膜不应全层切开

D.锤凿法劈开时,牙冠应已有足够的显露,且牙不松

E.涡轮钻拔牙术创伤小、但术后并发症多

答案

参考答案:D

解析:下颌第三磨牙拔除术注意事项:①远中切口如偏舌侧,易引起出血和水肿。②颊侧切口与远中切口的末端成45°角向下,勿超过前庭沟,否则将引起颊部肿胀。③应作黏骨膜全层切开,紧贴骨面将瓣翻起。④用锤凿法去骨时,为避免暴露第二磨牙牙根,应首先在第二磨牙颊远中角之后,与牙槽嵴垂直,凿透密质骨使成一沟。⑤用锤凿法劈开时,牙冠应已有足够的显露,且牙不松,在颊面近中发育沟处,用锐利而合适的器械劈开。⑥涡轮钻拔牙法是近年来较常使用的方法,具有无振动,创伤小,手术视野清楚,手术时间短,术后并发症减少等明显优点。
