Abstract

Objectives: To determine the fatigue resistance of occlusal veneers and whether it can be a successful mean of restoring erosive or attrite posterior teeth. Methods: Search was made in 2 databases including PubMed and LILACS, the terms “occlusal veneers”, “table tops”, “overlays”, “non retentive all ceramic full coverage restorations”, “fatigue resistance”, “ masticatory fatigue”, “stresses”, “fatigue failure” and “fracture strength” were used, title and abstract were screened; giving the exclusion and inclusion standards articles which did not follow the inclusion standards were excluded. Incorporated papers are then read thoroughly for a second stage filter, this was followed by manual searching. Findings: The search resulted in 6 included papers, 3 papers regarding the fatigue resistance of occlusal veneers made of composite and glass ceramic blocks, 1 paper measuring the fatigue resistance of occlusal veneers made of two different glass ceramics, 1 paper comparing occlusal veneers made of resin nano-ceramic with those made of composite blocks and 1 paper simulating five years of clinical service on occlusal veneers made of one type of glass ceramic. From the included studies occlusal veneers were found to be a successful mean of restoring erosive or attrite posterior teeth regarding fatigue resistance.
