In this study, we evaluated the clinical efficacy of mandible reconstruction with preoperative virtual planning, which focused on esthetics and occlusion.
A series of 9 patients were enrolled prospectively to undergo mandibulectomy and simultaneous reconstruction. Preoperative spiral CT scans of the maxillofacial region and the fibula region were performed. Virtual surgery of tumor resection and fibula reconstruction was performed in the Mimics platform. The reconstructed mandible models were fabricated with CAD/CAM technique. The reconstruction plate and the positioning template were accommodated to the stereolithographic model as the surgical template.
Surgery was performed accurately according to the templates. All the fibula flaps survived. The appearance and occlusion of the patients were satisfactory.
With preoperative virtual planning, the spatial relationship of the mandible and the fibula graft can be planned individually, which helps achieve optimum appearance and occlusion relationship.
本研究通过术前虚拟规划评估了专注于美观和咬合的下颌骨重建的临床疗效。
前瞻性地纳入了 9 例接受下颌骨切除术和同期重建的患者。对颌面区域和腓骨区域进行螺旋 CT 扫描。在 Mimics 平台上进行肿瘤切除和腓骨重建的虚拟手术。使用 CAD/CAM 技术制造重建下颌骨模型。将重建的下颌骨模型适配到立体光刻模型上作为手术模板。
根据模板精确进行了手术。所有的腓骨瓣均存活。患者的外观和咬合情况均令人满意。
通过术前虚拟规划，可以单独规划下颌骨和腓骨移植物的空间关系，有助于实现最佳的美观和咬合关系。
