Mandible fracture is a common injury in maxillofacial surgery. It causes not only maxillofacial dysfunction but also facial deformities. Malunited fractures of the mandible have been a vast challenge in clinical treatment due to the misalignment of the broken ends and the occurrence of occlusal disorders. This case report describes using virtual surgical planning and three-dimensional printing to treat a patient with malunited fracture of the mandible. Failing to perform mandibular surgery due to severe brain trauma after the car accident, the patient got malunited healing of mandible. The authors applied virtual surgical planning to perform preoperative analysis and surgical design on this patient, three-dimensional printing to fabricate occlusal plate, and models of the preoperative and postoperative mandible to guide the operation. Finally, the authors achieved the reduction and reconstruction of the mandible with satisfactory clinical results.
下颌骨骨折是颌面外科的常见损伤。它不仅导致颌面功能障碍，还导致面部畸形。由于骨折端的错位和咬合紊乱的发生，下颌骨愈合不良的骨折一直是临床治疗的巨大挑战。本病例报告描述了使用虚拟手术规划和三维打印技术治疗下颌骨愈合不良的患者。由于车祸后严重的脑外伤而无法进行下颌骨手术，该患者的下颌骨出现了愈合不良。作者应用虚拟手术规划对该患者进行术前分析和手术设计，三维打印制作咬合板和术前、术后下颌骨模型以指导手术。最终，作者实现了下颌骨的复位和重建，取得了满意的临床效果。
