Adaptação marginal em coroas de porcelana confeccionadas com diferentes materiais: uma revisão de literatura

Abstract

Porcelain crowns are indirect restorations that aim to restore lost dental elements, in order to rehabilitate aesthetics and function, restoring the patient's quality of life and self-esteem. The objective of this work was to evaluate the marginal adaptation of porcelain crowns of different materials of indirect restorations (feldspar, lithium disilicate, metalloceramics), through a literature review. The bibliographic survey was carried out through the databases PubMed, Lilacs (American Literature in Health Sciences) and Scielo (Scientific Electronic Library Online). The studies obtained were fully evaluated and after reading the abstracts and records, 33 publications were used to build the theoretical framework of the present study. Only publications that answer the study question were included, contemplating at least two descriptors, published in the period from 2005 to 2020, in Portuguese and English and in all types of methodological design. To be successful in the treatment of oral rehabilitation, it is necessary that the indirect restoration together with the dental preparation is in tune so that there is no marginal mismatch between both. The indication of the material of indirect restorations also differs for different cases.
