Optimizing adhesion in fixed prosthesis: literature review

Abstract

The objective of this work was to carry out a literature review to discuss how to optimize cementation in fixed prostheses, specifically the aim was to present solutions for hybridization and/or preparation of laminates, as well as the dental substrate. This is a narrative literature review. Due to methodological demands, publications related to the research objective were included, articles in portuguese or english, without limitation on publication date, available in full text. On the other hand, duplicate publications or those whose full text could not be found were excluded. The search for articles was carried out digitally, in the Virtual Health Library, Scientific Electronic Library Online and Google Scholar databases, using the following descriptors: immediate dentin sealing; dentin adhesives; dental cements; dentin. Immediate dentin sealing may be indicated, as long as it consists of applying a thin layer of adhesive after preparation and before temporary cementation. The technique allows the preservation of fresh dentin in its ideal condition for adhesion and reduces postoperative problems associated with prepared teeth, such as tooth sensitivity. Various adhesive systems, as well as resin cements, with different formulations and usage techniques, are available on the market. Immediate dentin sealing has advantages and controversies when compared to traditional procedures. Among the benefits cited by this approach, the authors studied highlighted improvements in bond strength to resin cements, as well as prevention of postoperative sensitivity in teeth prepared for indirect restorations.
