摘要：

目的 探讨面部不对称畸形患者的三维仿真头模术前设计对其术中上颌骨截骨的指导意义。方法 选择中国医科大学口腔医学院口腔颌面外科2007年1月至2009年1月收治的18例面部不对称畸形患者。所有患者畸形明显并且均伴有竖直方向牙合平面的倾斜。术前制作三维头模，精确测量之后在模型上模拟截断上颌骨，评价截骨的位置及截骨量，再将得到的数据应用到手术中行上颌骨截骨，术后6个月评价手术效果。结果 18例患者手术顺利，无严重并发症出现。所有患者术后效果满意，牙合平面均水平，面部对称。结论 通过三维头模模拟截骨得出的数据可用于精确指导术中的截骨，对于术中上颌骨截骨的位置及截骨量的确定具有重要的指导意义。

Abstract:

Objective To evaluate the significance of maxilla osteotomy during operation by designing and operating on patients with asymmetry deformities by using rapid prototyping technology. Methods Eighteen patients with asymmetry deformities were selected from Department of Oral Maxillofacial Surgery，School of Stomatology， China Medical University，between January 2007 and January 2009. For all the patients， the deformity was very obvious and the biteplane was inclined. By measuring the model which was made preoperatively and operating on it， the data was obtained and used to guide the operation. Finally evaluate the operative effect 6 months after operation. Results All the patients obtained satisfactory results and facial deformities were corrected successfully without serious complications.The biteplane was horizontal. Conclusion It is significant that we use the data obtained from operating on model to identify the position and quantity of maxilla osteotomy during operation.
