Patient-specific Reconstruction Plate for Segmental Mandibular Defects

Summary

The mandible's horseshoe-shaped anatomy makes the reconstruction of segmental defects a challenging procedure. Conventional reconstruction typically relies on alloplastic plates to bridge bony stumps; however, these require extensive intraoperative bending, often resulting in imperfect adaptation, press-to-contact fixation, and residual stresses that increase the risk of hardware fatigue and fracture. Recent advances in computer-aided design and manufacturing (CAD/CAM) and virtual surgical planning (VSP) have improved precision in maxillofacial reconstruction. Patient-Specific Reconstruction Plates (PSRP), developed from virtual planning and patient-specific anatomical data, offer a bespoke contour adaptation, predictable screw positioning, and elimination of press-fit deformation. This customization improves alignment, mechanical stability, and long-term outcomes.
