Mandibular reconstruction is often challenging. However, the revolution of computer-assisted design and computer-assisted manufacturing (CAD/CAM), virtual surgical planning (VSP) and 3D printing technology have changed this notion.
In this article, we have described six case scenarios where various aspects of VSP and 3D printing technology have been utilized for complex mandibular reconstruction procedures, to provide the patients with the best possible outcome in terms of form, function, and aesthetics.
Virtual planning for tumour resection and fibula osteotomies and 3D printing of cutting guides and stereolith models have changed the face of mandibular reconstruction techniques. Increased accuracy, rehabilitation of normal anatomical configuration, appropriate dental rehabilitation, decreased intra-operative time and post-operative complications are some of the advantages. In addition, patient-specific implants eliminate the need for a separate donor site. 3D printed titanium cribs or meshes not only provide robustness, but also incorporates additional features that enable bone graft placement and excellent dental rehabilitation.
These modalities show promising results for reconstruction of complex mandibular defects.
下颌骨重建往往具有挑战性。然而，计算机辅助设计与计算机辅助制造（CAD/CAM）、虚拟手术规划（VSP）以及3D打印技术的革新改变了这一观念。
在本文中，我们描述了六个病例场景，其中VSP和3D打印技术的各个方面已被用于复杂的下颌骨重建手术，以便在外形、功能和美观方面为患者提供尽可能最佳的结果。
肿瘤切除和腓骨截骨的虚拟规划以及切割导板和立体光刻模型的3D打印改变了下颌骨重建技术的面貌。提高的准确性、正常解剖结构的恢复、适当的牙齿修复、减少的手术时间和术后并发症都是其优点。此外，定制植入物消除了对单独供体部位的需求。3D打印的钛制框架或网片不仅提供了坚固性，还融入了能够进行骨移植放置和出色牙齿修复的额外特征。
这些方法在复杂下颌骨缺损的重建中显示出了有前景的结果。
