Cerâmicas odontológicas : uma visão integrativa destacando o desgaste dentário antagônico e sua longevidade em relação à fratura.

Abstract

The similarity to natural dental structures and the growing aesthetic demand idealized in society creates an increasingly requested need in dental offices to use ceramics for dental treatments. The restorative material, then, must be selected according to its properties, noting the importance of preserving the normal function of the other teeth and the balance of the joint, including analyzing its longevity in relation to its ability to withstand fractures and improving its clinical performance over time. over time. It is proposed, through this study, to carry out an integrative review of the literature on antagonistic tooth wear against ceramic materials and its longevity in relation to fracture. The study is characterized by an integrative literature review, including articles published between January 2017 and May 2022, in the CAPES Journal Portal database, using the Health Sciences Descriptors (DeCS) "dental porcelain”, “tooth wear”, “tooth enamel”, “longevity” and “fracture strength”, as well as their English equivalents. Initially, 161 articles were found, and duplicate articles, those that were not in English or Portuguese, those that did not address the topic, review and meta-analysis and literature articles were excluded, resulting in seven selected articles. The results were divided into two thematic fields of analysis: antagonistic tooth wear against dental ceramic materials; the longevity of prosthetic rehabilitations in relation to their fracture. The results pointed to different ways of evaluating antagonistic tooth wear provided by dental ceramics. They point out that feldspathic porcelain was the most harmful, followed by polymer infiltrated ceramics, polished zirconia, polished metal-ceramics (feldspar particles), polished Y-TZP, vitrified surface restorations and porcelain coated (nano-fluorapatite). Still, in relation to the fracture of dental ceramics, works with lithium disilicate presented success rates greater/equal to 97% in 10 years, in feldspar after 7 years, 91.77% and, after 15 years, longevity rates of all-ceramic crowns in approximately 95% of cases.
