Various studies have been conducted on the accuracy of CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing)-generated fixed dental prostheses (FDPs). Most of these studies investigated marginal/internal fit as an accuracy in CAD/CAM-generated FDPs. Mechanical and biological requirements can be met by acquiring excellent marginal/internal fit. However, CAD/CAM-generated FDPs should have a functionally and anatomically harmonic relationship with functional mandibular movements and antagonistic teeth to meet functional requirements. However, the details of the factors related to occlusal errors in the CAD/CAM system have not been revealed. In addition, it is difficult to evaluate the validity of restored occlusion using CAD/CAM-generated FDPs. Therefore, this article describes a new concept of accuracy for occlusal error reduction in CAD/CAM-generated FDPs.
