Digital dentistry has promoted significant changes in the diagnosis, planning, and execution of oral rehabilitation treatments, with Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) systems standing out as one of the main technological innovations applied to contemporary clinical practice. This study aimed to analyze the impacts of CAD/CAM systems on the accuracy and predictability of oral rehabilitation treatments through an integrative literature review. The bibliographic search was conducted in the PubMed/MEDLINE, ScienceDirect, and SciELO databases, including studies indexed between 2015 and 2025. After applying the inclusion and exclusion criteria, 12 studies composed the final sample of the review. The findings demonstrated that CAD/CAM systems provide satisfactory marginal and internal adaptation of restorations, contributing to greater prosthetic accuracy and clinical predictability. Furthermore, digital workflows have shown potential to optimize clinical and laboratory procedures, reduce treatment time, improve communication among professionals, and increase patient satisfaction. However, limitations related to case complexity, professional learning curves, and implementation costs still represent challenges for the widespread adoption of these technologies. It is concluded that CAD/CAM systems are effective tools in contemporary oral rehabilitation, promoting significant gains in accuracy, efficiency, and treatment predictability.
