Abstract: Objective: To evaluate the accuracy of the CAD/CAM implant template based on CBCT data for dental implants preparation. Methods: Jaws from 6 patients were scanned using cone beam computed tomography (CBCT). The CT data was used to fabricated CAD/CAM implant templates. Twenty-four implants were inserted in edentulous patients using CAD/CAM implant templates. All patients had CBCT scanning again after operation. Preoperative and postoperative computed tomographic images were compared, and the deviations between actual and planned implants were measured. Results: With the help of CAD/CAM implant templates, the neck deviation of the implant was 1.03±0.55mm, apical deviation was 1.19±0.56mm, and axis deviation was 3.12±2.64°. Conclusion: The CAD/CAM implant template can accurately transfer the preoperative design, reduce the risk of operation, and is worth for clinical use.
