摘要/Abstract

摘要： 目的：探讨数字化模型外科在牙颌面畸形治疗中的应用价值。方法：选取15例牙颌面畸形患者，通过CT重建模型与激光扫描牙列模型，构建数字化颅颌面-牙列模型，在此基础上进行手术设计，并且三维打印板及导板，指导手术。术后3个月进行面部对称性及手术精确度评价。结果：所有患者均顺利完成手术虚拟设计、板和导板三维打印以及正颌手术。偏颌畸形患者术后对称性明显改善，术后CT模型与术前设计比较，最大差异度<2 mm。结论：利用数字化模型外科可进行手术设计，模拟，预测，并且可以三维打印板及导板指导手术，在牙颌面畸形的治疗中具有广泛的应用价值，值得临床推广。

Abstract: PURPOSE : To explore the application of digital model surgery in the treatment of dento-maxillofacial deformities. METHODS : Fifteen patients of dento-maxillofacial deformities were enrolled in this study. Digital craniomaxillofacial-dentition model was established by combined 3D CT and laser-scanned dentition model. Based on this model, surgical planning, simulation and postoperative prediction were performed. Under the guidance of 3D printed splint and guide, orthognathic surgery and asymmetry correction were carried out. Clinical examination was performed 3 months after surgery. Surgical accuracy was evaluated by comparing the postoperative CT 3D model with preoperative surgical planning. RESULTS : All patients underwent virtual surgical planning, splint and guide 3D printing and orthognathic surgery successfully. Facial symmetry was greatly improved after surgery. The mean deviation between the preoperative design and actual surgical results was less than 2 mm. CONCLUSIONS : With the ability of preoperative planning, surgical simulation and postoperative prediction, digital model surgery shows its great value in improving the accuracy of orthognathic surgery and restoring facial symmetry. It is regarded as a valuable technique in this potentially complicated procedure.
