CERAMIC MATERIALS: A SYSTEMATIC REVIEW ABOUT WEAR AND LONGEVITY

Abstract

Introduction: The ceramic materials in the last decades, presented a great microstructural advance to meet the functional and aesthetic requirements, in order to increase the longevity of ceramic oral rehabilitations. However, the accentuated wear of the dental enamel has checked the indications and application of ceramic materials. Objective: To investigate the wear of different restorative materials and the antagonistic dental element, against the longevity of clinical use through a systematic review. Material and method: The present systematic review was carried out by search of scientific articles from the years 2006 to 2016, in the following databases: Bireme, Pubmed and Scielo, using the keywords: ceramic, dental wear and longevity. From the reviewed 13 articles, based on the degree of scientific evidence, 84,62% (n = 11) of the studies at level 3 and 15,38% (n = 2) are of level 8. Result: The reviewed studies presented differences of laboratory methods, which makes it difficult to discuss the results. Conclusion: The wear of the dental element antagonist (enamel) seems to be greater when an acid-sensitive ceramic is used; as for longevity the lithium disilicate presents the greatest loss of material.
