ИСПОЛЬЗОВАНИЕ 3D-ПЛАНИРОВАНИЯ И ХИРУРГИЧЕСКИХ ШАБЛОНОВ В СТОМАТОЛОГИЧЕСКОЙ ИМПЛАНТОЛОГИИ

Abstract

Purpose: To evaluate the effectiveness of implant treatment using computer 3D modeling and surgical guides. Materials and Methods: The study included 148 patients, who underwent prosthodontics rehabilitation, using dental implants in 2015- 2021. 3D computer-aided modeling and surgical guides were used to plan the operation. To conduct a comparative analysis of the treatment results, two groups were formed: group A (included 72 patients, fully guided surgery), and group B (included 76 patients). Results: In Group A intraoperative or immediate postoperative complications were recorded: (errors in the position, inclination), anatomical risk structures were invaded, 3 years later producing a survival rate of 96.2%. In Group B, intraoperative complications were recorded: membrane perforation (4), errors in the position of the implants (16), inclination of the implants (18), fenestration (12), 3 years later producing a survival rate of 97.6%. Mean marginal bone loss (MBL) in patients of group A was significantly higher than in patients of group B (p < 0.05). In patients of 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 of 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 the minimal trauma, reducing treatment time and complications.
