Objective:To evaluate the accuracy of surgical template designed and manufactured by computer(CAD/CAM)through applying the template to the implant operation. Method:Jaw of the patient and the radiographic template were scanned with double scanning CT technology. Inputting the DICOM dates obtained into Procera software, we can re-construct the 3-D jaw,simulate the implantation,then design and fabricate the surgical template. Through the surgical tem-plate,we can make the model and then make the temporary prosthesis. The accuracy of surgical template was evaluated by the emplacement of the temporary prosthesis. Result:The operations guided by surgical templates were all finished success-fully and temporary prostheses were all emplaced fully. Conclusion:CAD/CAM template had high precision in guiding plant operation and improved the accuracy of implantation greatly.
