Abstract: Aim: To assess the occlusal efficacy of CAD-created occlusal anatomy and hand layered occlusal anatomy in fixed dental prosthesis using Digital occlusal analysis (T-scan) in literature. Methods and Material: For the identification of studies, detailed search strategies were developed for the database searched (i.e. PUBMED CENTRAL, Google and Hand Search) till January 2022. Studies that compare different materials for CAD-CAM crowns, studies using digital occlusal analysis, studies comparing occlusal and disocclusal timing using T-scan, clinical trials and prospective studies were considered for this review. Results: Out of 119 articles obtained from the electronic search, 97 were excluded due to irrelevance of the title and abstract to the topic of interest and 10 were excluded on the basis of core data. A total of 12 articles were reviewed. PRISMA chart depicts the article selection process for this systematic review which compared prosthetic replacement and occlusal efficacy using a digital occlusal analysis. Conclusion: This review concludes that the studies considered have a high risk of quality bias. However, results of included studies concluded that there was a significant difference in using T-scan for occlusal equilibration for fixed dental prosthesis – CAD-created and hand layered occlusal anatomy and is a reliable tool as it shows the Occlusal and Disocclusal Timing and the Intensity of Contact load in percentage compared with the traditional articulating paper. Hence further clinical trials need to be conducted with proper sample size calculation, blinding and randomization to obtain accurate results.
