Abstract

Introduction: Recetly, with the development of the rapid prototyping (RP) technique, the implant surgical guide template has become more and more popular in clinic. This digital guide template seems to express great potential for accuracy and simplification. However, it is not completely clear whether the surgical template can actually increase the accuracy of the implant.

Purpose: The purpose of this study was to assess the accuracy of implant placement using surgical guide templates.
Materials & Methods: A total of 4 patients with missing teeth were included in our study. Preoperative cone beam computed tomography (CBCT) was performed and preoperative planning was designed with softwarefor all patients. Implant surgical guide templates were designed and produced by a RP technique. Postoperative CBCT was performed for all patients. Image registration was carried out between postoperative CBCT data and that of preoperative planning data. Deviations of the implant between the actual and planned positions were measured and compared.

Results: The overall mean deviation at the entry point was 0.63±0.37 mm and at the apex was 0.62±0.43 mm in buccolingual direction and at the apical direction was 0.39±0.33. Finally, the mean deviation of implant angulation was 0.75±0.67o .

Conclusions: The result of implant position placed with surgical guide templates has not significant difference from planned position in implant shoulder, apex, and angulation. Thus, is much more suitable for complicated procedures and conditions such as the flapless method, immediate loading, aesthetic restoration, and insufficient bone height.
