Research progress on fixation methods for mandibular defect reconstruction

The mandible plays a crucial role in facial structure and function. Mandibular defects, often caused by tumor resection, trauma, or congenital conditions, severely impact patients' physiological functions and quality of life. Reconstruction methods for mandibular defects primarily include autologous bone grafting, computer-aided reconstruction, and distraction osteogenesis. Among these, autologous bone grafting remains the most widely used technique. As medical technologies advance, the integration of computer-aided design and 3D printing has provided new technical support for personalized mandibular reconstruction, improving both surgical precision and safety. Moreover, distraction osteogenesis has emerged as a promising alternative in recent years. This paper reviews research on fixation methods for V mandibular defect reconstruction to offer clinical guidance for effective mandibular repair.
