摘要：

目的    探讨数字化技术在牙颌面畸形治疗中的应用。 方法    选择2014年12月至2015年12月于中国医科大学附属口腔医院口腔颌面外科行正颌手术的牙颌面畸形患者12例，通过上下颌骨3D-CT重建DICOM数据，构建数字化头颅模型并3D打印头颅模型，进行手术前模拟设计，模拟截骨，指导手术。术后3个月进行面部对称性评价。结果    所选12例患者均完成手术模拟并3D打印头颅模型，最后进行正颌手术。术后3个月复查面部对称性改善明显。满意率达到91.67%。结论    利用数字化技术进行手术模拟设计，3D打印头颅模型模拟截骨，并指导手术，提高手术精确度，在牙颌面畸形的治疗中具有实际的应用价值。

Abstract:

Objective    To explore the application of digital technology to the treatment of dento-maxillofacial deformities. Methods    Twelve patients with dento-maxillofacial deformities were enrolled and DICOM data were reconstructed with 3D-CT of maxillary and mandible. The DICOM data were input into the software of Proplan CMF. We built digital skull model and 3D-printed skull model to perform surgical planning， postoperative prediction and simulate operation. Clinical examinations of facial symmetry were performed 3 months later. Results    All the surgical plannings， postoperative predictions and simulate operations of the twelve patients with dento-maxillofacial deformities were performed. And the orthognathic surgery was successfully. The patients were satisfied with the facial symmetry 3 months after operations， with a satisfaction rate of 91.67%。 Conclusion    When using digital technology to perform surgical planning and simulate operation，the accuracy of surgeries is improved with satisfactory effect. So the digital technology has practical value in the treatment of dento-maxillofacial deformities.
