Surgical removal of third molars is associated with complications that can be as common as pain and trismus and as rare as mandibular fracture. A fracture can occur when the resistance of the bone tissue is lower than the forces applied by the surgeon during the procedure. The aim of this article is to report a case of jaw fracture after tooth extraction and subsequent surgical treatment of the fracture under general anesthesia with an option for a submandibular approach. A plate and screw system with a 2.4-mm profile was used for osteosynthesis after reduction of the fracture. The patient was followed up for 6 months after surgery and reported no functional or esthetic complaints. Treatment of mandibular fractures should aim to reestablish functional occlusion and mandibular continuity with the least possible risk of adverse sequelae. Planning for each individual case of third molar extraction requires accurate clinical examination and image evaluation to lessen the risk of fracture.
拔除第三磨牙手术会引发一些并发症，常见的如疼痛和牙关紧闭，罕见的如下颌骨骨折。当骨组织的阻力低于手术过程中外科医生施加的力时，就可能发生骨折。本文旨在报告一例拔牙后颌骨骨折的病例，以及随后在全身麻醉下采用下颌下入路对骨折进行手术治疗的情况。骨折复位后，使用了轮廓为2.4毫米的接骨板和螺钉系统进行骨固定。术后对患者进行了6个月的随访，患者未报告任何功能或美观方面的问题。下颌骨骨折的治疗应以重建功能咬合和下颌连续性为目标，同时尽量降低出现不良后遗症的风险。每例第三磨牙拔除病例的规划都需要进行准确的临床检查和影像评估，以降低骨折风险。
