This clinical report presents a technique to reconstruct extensively resected mandibles using a combination of autologous bone grafts and additive manufacturing techniques. Mandibular defects, often arising from trauma, tumors, or congenital anomalies, can severely impact both function and aesthetics. Conventional reconstruction methods have their limitations, often resulting in suboptimal outcomes. In these reports, we detail clinical cases where patients with different mandibular defects underwent reconstructive surgery. In each instance, autologous grafts were harvested to ensure the restoration of native bone tissue, while advanced virtual planning techniques were employed for precise graft design and dental implant placement. The patients experienced substantial improvements in masticatory function, speech, and facial aesthetics. Utilizing autologous grafts minimized the risk of rejection and complications associated with foreign materials. The integration of virtual planning precision allowed customized solutions, reducing surgical duration and optimizing implant positioning. These 2 cases underscores the potential of combining autologous grafts with virtual planning precision and dental implants produced by additive manufacturing for mandible reconstruction.
本临床报告介绍了一种使用自体骨移植和增材制造技术相结合来重建广泛切除下颌骨的技术。下颌骨缺损通常由创伤、肿瘤或先天性异常引起,会严重影响功能和美观。传统的重建方法有其局限性,往往导致不理想的结果。在这些报告中,我们详细介绍了不同下颌骨缺损患者接受重建手术的临床病例。在每个病例中,均采集自体移植物以确保恢复天然骨组织,同时采用先进的虚拟规划技术进行精确的移植物设计和牙种植体植入。患者在咀嚼功能、言语和面部美观方面有了显著改善。使用自体移植物可将与异物相关的排斥反应和并发症风险降至最低。虚拟规划精度的整合实现了定制化解决方案,缩短了手术时间并优化了种植体定位。这2例病例凸显了将自体移植物与虚拟规划精度以及增材制造生产的牙种植体相结合用于下颌骨重建的潜力。
