[Research and clinical application of computer-aided design of craniofacial prosthesis using mirror technique].

Objective: To explore the feasibility of creating a 3D-CAD model of craniofacial prostheses through mirror technique to repair the unilateral craniofacial defects and restore craniofacial symmetry.
Methods: Patients with unilateral craniofacial defects underwent spiral CT scanning. CAD3-D image was reconstructed ad 3-D CAD model of craniofacial prosthesis was created with mirror technique, Boolean operation and rapid prototyping technique. Then the prosthesis made of bioactive artificial bone was made through plaster cavity block.
Results: 15 cases were treated with no complications. Good symmetry was achieved after operation.
Conclusions: Designing the craniofacial prosthesis with mirror technique guarantees excellent functional and cosmetic results for repairing the unilateral craniofacial defects.
