Abstract：
Mandibular angle fractures have the greatest recorded rate of postoperative complications of any mandibular location and hence they present an especially difficult task for surgeons. Therefore, it is of interest to compare the conventional miniplates and three dimensional (3D) plates in management of mandibular angle fracture and body fractures.60 patients with isolated non-comminuted mandibular angle fractures and body fractures were randomly assigned into two groups by lottery. Utilizing Champy\'s osteosynthesis standards, group one (n = 30) received treatment with 2-mm standard miniplate and group two (n = 30) had treatment with open reduction and internal fixation utilizing 2-mm 3D locking stainless steel plates. The mean operative time was greater in conventional miniplate category as compared to three dimensional plates. Need for postoperative occlusion correction was lesser n 3 dimensional plate category. The incidence of postoperative infection was comparable in both categories. Incidental tooth damage was lesser in three-dimensional plate\'s category three-dimensional locking plates are an alternate strategy that has a comparable result profile to miniplates.
摘要：
下颌角骨折在任何下颌位置的术后并发症发生率最高，因此对外科医生来说是一项特别困难的任务。因此,比较常规微型钢板和三维(3D)钢板在下颌角骨折和体部骨折治疗中的应用是有意义的.60例孤立性非粉碎性下颌角骨折和体部骨折患者随机分为两组.利用Champy的接骨术标准，第一组（n=30）接受2-mm标准微型钢板治疗，第二组（n=30）接受2-mm3D锁定不锈钢板切开复位内固定治疗。与三维板相比，传统微型板类别的平均手术时间更长。术后闭塞校正的需求较小，n3维板类别。两种类型的术后感染发生率相当。在三维钢板的类别中，偶然的牙齿损伤较小。三维锁定钢板是一种替代策略，具有与微型钢板相当的结果轮廓。
