Resumen
The aim of this systematic review is to summarize and analyze the scientific
evidence evaluating the mechanical performance of Computer Aided Design,
Computer Aided Manufacturing (CAD/CAM) composite resin and CAD/CAM lithium
disilicate ceramic occlusal veneers, in terms of fatigue and fracture resistance, on
severely worn posterior teeth. Currently, occlusal veneers are an alternative for
treating worn posterior teeth. Even though there is scientific evidence demonstrating
the good performance of lithium disilicate occlusal veneers, there are now more
materials that are less brittle and have a modulus of elasticity more similar to dentin
than ceramics, such as resin CAD/CAM blocks. Therefore, it is important to identify
which type of material is best for restoring teeth with occlusal wear defects that can
provide better clinical performance. This review followed the Preferred Reporting
Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. We
performed a search in the Pubmed, Embase, Web of Science, Scopus, Cochrane,
Open Gray, Redalyc, Dspace, and Grey Literature Report databases, supplemented
by a manual search, without time or language limitation, until January 2022, for
studies evaluating the fatigue and fracture resistance of CAD/CAM composite resin

and ceramic occlusal veneers. The quality of the full-text articles was analyzed
according to the modified CONSORT criteria for in vitro studies, and 400 articles
were initially identified. After removing duplicate studies and applying the selection
criteria, the systematic review finally included 6 studies. The CAD/CAM composite
resin occlusal veneers have similar mechanical performance in terms of fatigue and
fracture resistance as CAD/CAM lithium disilicate occlusal veneers.
