Abstract:

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.
