中文摘要
目的 探讨采用计算机辅助设计与计算机辅助制造（CAD/CAM）方法制造个体化舌侧矫治器的可行性。方法 运用三维激光扫描仪采集与重建牙颌模型数据，并以该数字模型为基础，应用三维软件进行个体化舌侧托槽的CAD，通过快速成型与铸造技术将CAD 托槽转化制作为个体化舌侧金属托槽，再根据CAD 个体化弓形图弯制个体化弓丝。结果 三维激光扫描仪获得的牙颌模型数据可以满足个体化舌侧托槽和弓形图CAD 的要求；应用CAD/CAM 方法能够制作出与实际牙颌模型相一致的个体化舌侧托槽和弓丝。结论 应用CAD/CAM方法制造个体化舌侧矫治器方法可行。
英文摘要
Objective To assess the feasibility in production of individualized lingual bracket system using computer aided design/computer aided manufacturing（CAD/CAM） technique. Methods The cast model was scanned by optical 3D scanner and 3-dimension digital model was reconstructed with appropriately designed software. The individualized lingual brackets could be designed with appropriate design software（CAD program）. Using high-end rapid prototyping machine and casting technique, the virtual bracket series were converted into metal ones. According to the archwire geometry designed by CAD technique, the individualized lingual archwires were manufactured. Results The reconstructed 3-dimension digital model could be suitable to design the virtual individualized lingual bracket and archwire geometry. The virtual individualized lingual bracket and archwire geometry are in accordance with a real-life metal brackets and archwires on the cast model. Conclusion The use of CAD/CAM technology can produce individualized bracket system in lingual orthodontics.
