Abstract: Objective To explore the feasibility and effectiveness of using CAD/CAM combined with individualized titanium mesh and iliac bone graft to repair unilateral large-sized mandibular contour defects. Methods From November 2015 to December 2019, fifteen patients with unilateral large-sized mandibular contour defects were enrolled in this study. Personalized preformed titanium mesh and mandible models were fabricated by computer-aided design/computer-aided manufacture (CAD/CAM) based on reverse engineering to reconstruct mandibular contour defect. Two patients accepted genioplasty to adjust the deflective region. Length of the bilateral mandibular ramus and mandibular body and its three-dimensionality were measured and compared to analyze symmetries of mandibular contour after surgery. Results All patients have satisfactory results and no adverse complications. Measurements showed satisfactory symmetries of mandibular contour in the 3D position after surgery (P>0.05). Conclusion The study suggests that this technique was feasible and efficient for the reconstruction of unilateral large-sized mandibular contour defects.
