Biomechanics of alloplastic mandible reconstruction using biomaterials: The effect of implant design on stress concentration influences choice of material.

Introduction: Mandibular endoprostheses have been explored extensively as potential methods of alloplastic reconstruction. Studies, however, have demonstrated that for segmental mandibular defects, there are challenges associated with loosening. Another method recently introduced in clinical settings is popular as a design for patient-specific implants for segmental mandibular defect and involves a tray (filled with bone) over the defect with wings on both sides secured with screws.
