Abstract

Background: Dental implantation is a standard procedure for replacing missing teeth. The utilization of a cone beam computed tomography (CBCT)-assisted surgical template allows predictable flapless results, with implant placement plans performed with accuracy before the actual surgery. Aim: The study was conducted to evaluate the accuracy degree of computer-guided 3D planning program 3Shape for implant insertion in partially edentulous patients. Methods: Computer-guided implant surgery was performed in 23 patients with 57 implants in total. Preoperative CBCT scans were fused with patient’s casts to produce the surgical templates. Postsurgery CBCTs were also performed after the implant placement. The collected data were used to analyze the possible differences of the implant fixture body placement between preoperative plan and postoperative actually placed implant, evaluating the angulation and distance errors. Results: The mean angulation errors between the preoperative planned and postoperative placed implant was 5.84° ± 1.87°; the mean distance errors between the planned and actually placed implants were 0.67 ± 0.38 mm horizontally and 0.74 ± 0.48 mm vertically at the implant neck and 0.82 ± 0.51 mm horizontally and 0.74 ± 0.39 mm vertically at the implant apex for all 57 implants. Conclusions: Computer-guided implant planning and insertion with 3Shape software, seems to provide sufficient accuracy, although more clinical studies should be conducted. Deviations are mainly related to CBCT accuracy and the implementation of the digital radiographic data to the 3D model through the software planning system.
