Application of CAD/CAM technique in three-dimensional reconstruction of zygomatic complex defect

To evaluate the efficacy of computer-aided design and computer-aided manufacturing (CAD/CAM) technique in reconstruction of zygomatic complex defect. Three-dimensional computed tomography (3D-CT) and rapid prototyping (RP) techniques were applied to produce facsimile models in 13 patients with zygom...

description	To evaluate the efficacy of computer-aided design and computer-aided manufacturing (CAD/CAM) technique in reconstruction of zygomatic complex defect. Three-dimensional computed tomography (3D-CT) and rapid prototyping (RP) techniques were applied to produce facsimile models in 13 patients with zygomatic complex defects resulted from trauma or tumor ablation. The zygomatic complex defect was reconstructed using a mirroring technique by CAD/CAM. Titanium mesh was prefabricated on individual facsimile models and combined with autologous bone graft and pedicled buccal fat pad flap for reconstruction. The measuring data of zygomatic complex defect between facsimile model and intraoperative findings was extremely consistent. The prefabrication of reconstructive titanium mesh was matched with zygomatic complex defect in the surgery. The postoperative 3D-CT image demonstrated the symmetry of reconstructed zygomatic complex. The functional recovery and facial contours were satisfactory in all cases. The application of
