Mandibular Reconstruction Modalities Using Virtual Surgical Planning and 3D Printing Technology: A Tertiary Care Centre Experience

Introduction: 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. Patients and Methods: 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. Discussion: 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. Conclusion: These modalities show promising results for reconstruction of complex mandibular defects.
