Abstract:
Objective To apply the techniques of CAD/CAM in the repair of defects and correction of deformity on the jaw bones so as to improve the accuracy and controllability of operations.Methods With CAD techniques,3D bone model was reconstructed based on CT images.Then,a repairing model was created with mirror operation on original model.The physical models of original model and repairing model were fabricated through rapid prototyping.Based on physical models,operation plan and model surgery with pre-forming plate could be designed.Results The designed operation plan and pre-forming plate techniques of CAD/CAM were successfully applied in eight patients,with satisfactory results.Conclusions With techniques of CAD/CAM,reconstructing and fabricating the original bone model and mirror repair model are very helpful for designing operation plan for maxillofacial surgery.It also can improve the surgery accuracy and save operation time obviously.
