Comminuted mandibular fracture poses a surgical challenge. Extensive comminution and absence of reference adds complexity particularly in anterior region. In this technical note, we describe a novel application of virtual surgical planning combined with 3D printing which grants precise anatomic reduction in such cases. Computed Tomography data (mandible) of another patient of same age and sex was utilized to create reference model by virtual surgical planning. Virtually created model was 3D printed and utilized for precontouring the reconstruction plate which assisted in achieving satisfactory outcome.
粉碎性下颌骨骨折带来了手术挑战。广泛的粉碎以及缺乏参考标志增加了复杂性，尤其是在前部区域。在本技术说明中，我们描述了虚拟手术规划与3D打印的一种新应用，其在此类病例中可实现精确的解剖复位。利用另一名年龄和性别相同患者的计算机断层扫描数据（下颌骨），通过虚拟手术规划创建参考模型。将虚拟创建的模型进行3D打印，并用于对重建钢板进行预塑形，这有助于获得满意的结果。
