【摘要】：目的:建立一种新生儿腭裂外鼻畸形鼻撑矫治器的计算机辅助设计与制作方法。方法:随机选取1名单侧完全性腭裂新生儿,用三维人体测量系统扫描患者面部获取患儿鼻-唇部三维原始数据;用逆向工程软件三维重建鼻-唇部数字化模型,将健侧外鼻数据镜像翻转至患侧,通过逆向工程软件完成鼻撑设计,快速成型技术将鼻撑数据自动加工成树脂原型,并在临床戴用检验其矫治效果。结果:三维人体测量系统0.1 s内完成了唇腭裂患儿面部的扫描,逆向工程软件三维重建出患儿鼻-唇部数字化模型,按要求完成了鼻撑矫治器的个性化设计。快速成型精确自动加工出鼻撑树脂原型,被成功用于患儿外鼻畸形矫治,效果理想。结论:计算机辅助设计与制造技术可以为唇腭裂外鼻畸形患儿设计和制作个性化的鼻撑矫治器。
[Abstract]:Objective: to establish a method of computer aided design and manufacture of nasal bracing appliance for cleft palate of newborn. Methods: 1 newborns with complete cleft palate were randomly selected, and the nasolabial 3D data were obtained by 3D anthropometric system, and the nasolabial digital model was reconstructed by reverse engineering software. The image of external nasal data of healthy side was turned over to the affected side, and the design of nasal braces was completed by reverse engineering software. The data of nasal braces were automatically processed into resin prototype by rapid prototyping technology, and the effect of correction was tested in clinical application. Results: the facial scan of cleft lip and palate was completed in 0.1 s by 3D anthropometric system. The digital model of nasolabial was reconstructed by reverse engineering software, and the individualized design of nasal bracing appliance was completed according to the requirements. Rapid Prototyping (RPM) was successfully used to correct the external nasal deformity in children. Conclusion: computer aided design and manufacture technique can be used to design and make individualized nasal bracing appliance for cleft lip and palate patients.
