Abstract

The goal of this work is to carry out a systematic review to assess the evidence about the potential advantages and accuracy of the marginal ridge of digital impression techniques in comparison to traditional impression techniques. A comprehensive search was conducted through the following databases to find publications that contrasted electronic impression techniques with traditional impression techniques: Cochrane Central Register of Controlled Trials, Web of Science, and PubMed. Free-text terms, a restricted vocabulary, and well-defined inclusion and exclusion criteria were all used in the search. The accuracy of the marginal ridge of fixed zirconia prosthesis in digital impressions is comparable to traditional impression techniques, the result shows It is therapeutically appropriate to use digital impression accuracy for the manufacture of Zr FDPs. Conventional impression techniques produced accurate impressions. For creating Z-crowns and short FDPs, digital impression techniques offer an acceptable substitute for traditional imprint techniques. Furthermore, the creation of Zr FDPs uses digital imprint technology to provide a clinically appropriate fit. It is possible to reduce the operation time by employing faster digital impression techniques. This study suggests that full-arch impressions should be taken using the conventional impression procedure.
