Preheated resin as a cementing agent in fixed prosthesis: Literature review

Abstract

Objective: Collect information on the use of preheated resin as a cementing agent and verify through scientific evidence if it can be considered an optimal option for its use. Materials and methods: A bibliographic search was carried out in PubMed, Scielo, Refseek and LILACS. Included are publications in English and Spanish, published between 2018 and 2022, literature reviews, systematic reviews, clinical case reports, in vitro studies, and experimental studies. Duplicate articles, inaccessible due to cost and that do not refer to the preheated resin as a cementing agent were excluded. A total of 346 publications were found, of which, after applying the inclusion and exclusion criteria, 20 articles were selected. Conclusions: The preheating of the composite resin presents several clinical benefits such as: reduction of viscosity, better marginal conformability, increase of microhardness, rigidity and degree of conversion.The increase in pulp temperature can be harmless when the temperature of the material is up to 60°. It can be considered appropriate for clinical implementation.
