Digital dentistry and guided treatments: a concise systematic review

Introduction: In the landscape of new digital technologies, many dental treatments have benefited from this digital advance. The development of computed tomography (CT) dental scanners has enabled powerful imaging capabilities and software applications. The prosthetic plane and implanted drill guides with the placement of trajectories based on a drill according to the position of the CT 3-D Space markers. Objective: To present, through a systematic review, the main considerations of guided surgery in implant dentistry and its respective advantages, disadvantages, and limitations. Methods: Clinical studies with qualitative and/or quantitative analysis were included, following the rules of the systematic review-PRISMA. Results: Out of a total of 102 articles found, 82 articles were evaluated and 57 were rejected for not meeting the GRADE classification, and only 25 articles were used in this study to compose the textual part. Advances in technology have contributed to the improvement of implant models. 3D reconstructions make it possible to determine the quantity and quality of available bone and also enable the simulation of implant installation in a virtual environment, reducing time and the possibility of errors, allowing for an overall reduction in the costs of oral rehabilitation. Conclusion: Guided preoperative planning or project-guided dental surgery provides high implant and dental rehabilitation success rates, also benefiting prosthetic restorations supported by fixed implants. Furthermore, the concept of using personalized implants with the help of 3D virtual treatment planning improves mandibular restoration with a good facial profile, esthetics, and dental rehabilitation
