Accuracy Computer-Guided Implant Placement using 3D Planning Software

Abstract

Purpose: To evaluate the effectiveness of implant treatment using computer 3D modeling and surgical guided. Materials and Methods: The study included 148 patients who underwent prosthodontics rehabilitation using dental implants in 2015-2020. 3D computer-aided modeling and surgical guide were used to plan the operation. To conduct a comparative analysis of the treatment results, two groups were formed: In group A (included 75 patients, fully guided surgery), in group B (included 73 patients). Results: In patients Group A intraoperative or immediate postoperative complications were noted (errors in the position, inclination), anatomical risk structures were invaded, after 3 years producing a survival rate of 96.2% In patients Group B, intraoperative complications were recorded; membrane perforation 4, errors in the position of the implants 16, the inclination of the implants 18, fenestration 12, after 3 years producing a survival rate of 97.6%. Mean marginal bone loss (MBL) patients in Group A were significantly higher than patients in group B (p < 0.05). In patients Group A the average surgical time from time of anesthesia to the placement of the healing abutment was 10.6 ± 2.9 min per implant, in patients Group B, the average surgical time was 16.4 ± 1.5 min per implant. Conclusion: The 3D modeling method and the controlled positioning of the implant allows surgical access with minimal trauma, reducing treatment time and complications.
