To obtain accurate occlusion in mandibular reconstruction when the tumor is exophytic, which makes prebending the plate impossible.
Use of computed tomography-based resin models and external fixation devices is combined in a tertiary academic center. The exophytic part of the tumor on the model is burred off, and the reconstruction plate is bent on the model before surgery. Temporary external fixation is applied before resection, and a precontoured plate is applied following segmental resection before the release of external fixation.
Six patients underwent mandibular reconstruction by using this technique, and all of the patients retained a class 1 occlusal relationship without need for additional intraoperative plate contouring.
Computer-generated resin models of the mandible combined with intraoperative temporary external fixation allow the maintenance of preoperative occlusal status.
当肿瘤呈外生性生长导致无法对钢板进行预弯时，在进行下颌骨重建时获得精确的咬合关系。
在一家三级学术中心将基于计算机断层扫描的树脂模型与外固定装置联合使用。在模型上磨除肿瘤的外生部分，术前在模型上对重建钢板进行弯曲。切除术前应用临时外固定，节段性切除后在解除外固定之前应用预塑形钢板。
6例患者采用该技术进行下颌骨重建，所有患者均保持Ⅰ类咬合关系，无需术中对钢板进行额外塑形。
计算机生成的下颌骨树脂模型联合术中临时外固定可维持术前咬合状态。
