数字化制作翼状导板应用于下颌骨节段性缺损1例报告及文献复习OA

Suppurative infection,trauma,and tumors in the maxillofacial region may cause segmental mandibular defects,resulting in loss of mandibular continuity and functional imbalance of the stomatognathic system.This report describes a case of a patient with a mandibular segmental defect who required removal of the original fixation titanium plate because of repeated postoperative infections.Based on preoperative intraoral scan data,a digitally designed and fabricated guiding flange prosthesis was used to maintain the postoperative mandibular position and occlusal relationship,providing favorable conditions for subsequent mandibular reconstruction.
