阻生齿拔除术是牙槽外科最常见的临床操作,常伴有牙根折断,邻牙及对颌牙损伤,术后肿胀,开口困难,感染及干槽症等常见并发症。由阻生齿拔除而导致的下颌角骨折发生率比较低,一旦发生就对患者造成非常严重的影响。本文将分别从拔牙术前,术中及术后分析可能导致下颌角骨折的诱因作一综述。 Impacted tooth extraction is the most common clinical practice of alveolar surgery, often accompanied by root fracture, adjacent teeth and maxillary teeth injury, postoperative swelling, opening difficulties, infections and dry trough and other common complications. The incidence of mandibular angle fractures caused by the removal of impacted teeth is relatively low, and in the event of a very serious impact on the patient. This article will review the reasons that may lead to mandibular angle fracture before, during and after extraction respectively.
