ObjectiveThe purpose of this study was to evaluate the clinical application of individual craniofacial bone fabrications using computer-assisted design and manufacturing (CAD/CAM) technology for the reconstruction of craniofacial bone defects.MethodsA total of 8 patients diagnosed with craniofacial bone defects were enrolled in this study between May 2007 and August 2010. After computer tomography scans were obtained, the patients were fitted with artificial bone that was created using CAD software, rapid prototyping technology, and epoxy-methyl acrylate resin and hydroxyapatite (EH) materials. The fabrication was fixed to the defect area with titanium screws, and soft tissue defects were repaired if necessary.ResultsThe fabrications were precisely fixed to the defect areas, and all wounds healed well without any serious complications except for one case with intraoral incision dehiscence, which required further treatment. Postoperative curative effects were retrospectively observed after 6 to 48 months, acceptable anatomic and cosmetic outcomes were obtained, and no rejections or other complications occurred.ConclusionThe use of CAD/CAM technology-assisted EH composite artificial bone to treat patients with craniofacial bone defects could enable the precise reconstruction of craniofacial bone defects and obtain good anatomic and cosmetic outcomes.
