3DSS结构光三维扫描系统在单侧眼眶缺损修复中的应用研究

Exploratory Development of 3DSS Three-dimensional Scanning System on Unilateral Orbital Defect Restoration

目的:探讨结构光三维扫描系统3DSS在重建单侧眶缺损患者面部三维数字化模型的准确性。方法:使用3DSS扫描结构光仪对一例单侧眼眶部患者眼眶进行面部结构扫描并采集数据,利用SLS快速成型机将重建的数字化模型加工成蜡模型。利用快速成型技术制作出修复体的树脂模型。结果:三维重建后的数字化实体模型平滑完整,边界过度自然,设计制作出的树脂修复体与缺损处贴和紧密并达到了逼真的对称修复效果。结论:采用该系统可以成功完成单侧眼眶部缺损修复的设计和制作,最终满足临床赝复体制作的需要。

Objective To discuss the accuracy of 3DSS three-dimensional scanning system, which was used to reconstructthe 3D digital model of unilateral orbital defect patients, Methods By using 3DSS spectrometer on the case of patients with unilateral orbital defect, the related scan dates of facial structure were collected, and the reconstructed digital models were processed wax pattern by SLS prototyping machine. Results The digital solid model of three-dimensional reconstruction was smooth and complete, and border over the natural. The designed resin prosthesis can be inosculated with the orbital defect tightly and symmetrically. Conclusion To adopt the system can be successfully completed unilateral orbital defect restoration design and production, and ultimately satisfied the clinical requirement of prosthesis production.
