Abstract: Objective: To explore the influence of a universal implant guide on the accuracy and clinical effect of implant surgery in the aesthetic area. Methods: With computer-guided surgery the position of the planned implants was compared to the actual position of the implants. The preoperative computed tomography data was matched with the postoperative computed tomography data by using exocad software. A analysis was used to evaluate the effect on the implant accuracy and angle. The clinical effect was evaluated 2 weeks after repair. Results: (1) The accuracy of the implant neck and root was controlled within 1mm and the average angular deviation of the implant neck and root was less then 5°. (2) The clinical results was good. The implant angle and gingival margin position were basically the same as the design. Conclusion: The universal implant guide has high accuracy, small devitation angle, and satisfactory clinical results.
