摘要
目的 了解反求工程和快速成型技术对单侧眼眶部缺损进行计算机辅助设计和制作的效果。方法 通过激光扫描仪对一例单侧眼眶部缺损石膏面部模型进行数据采集。经反求工程软件处理 ,依据健侧眼眶部组织数据设计出缺损处修复体表面数据 ,并利用模具软件设计出修复体模型的三维数据。最后通过快速成型方法制作出修复体的树脂模型。结果 激光扫描采得的模型点云数据清晰精确。利用健侧眼眶部组织数据修复患侧缺损获得满意效果之后设计制作出的树脂修复体与缺损处贴和紧密并达到逼真的对称修复效果。结论 利用反求工程和快速成型方法可以满意地完成单侧眼眶部缺损修复的计算机辅助设计和制作。
Objective By reverse engineering and rapid prototyping techniques to found a new design method of maxillofacial restoration.Methods By laser scanning apparatus the plaster face model was scanned and the primitive face point data were acquired. With the reverse engineering software, the point data were reconstructed to one smooth face surface image and the defect orbital tissue shape data was obtained from the normal contralateral tissue data in the software. The model designed the three-dimensional data of defect part and the rapid prototyping technique made the resin orbital restoration.Results The laser scanning apparatus acquired the distinct and precise model data of the plaster face-model. The Digisurface retrograde engineer software succeeded to fulfill the unilateral orbital defect computer-aided design. The orbital restoration inosculated the plaster model tightly and symmetrically.Conclusion The reverse engineering software and rapid prototyping technique could finish the computer-aided design and manufacture of the unilateral orbital defect restoration smoothly and satisfactorily.
