Restaurações estéticas com injeção de resina fluida nos dentes anteriores: uma alternativa ao tratamento convencional com cerâmica - revisão de literatura

Abstract

Introduction: Anterior restorations are sometimes difficult and time-consuming because they involve an aesthetic character. Composite resin has been used in the manufacture of veneers for these teeth, however, they demand greater skill in sculpting from the dentist. The injection technique with fluid composite resin in a silicone mold has been shown to be a good alternative for those with less experience with the incremental technique. Objectives:. The objective of this study was to report, through a literature review, the technique of injection of fluid composite resin in anterior teeth and to compare advantages and disadvantages of its use in patients who present aesthetic and/or functional dental problems. Material and methods: A literature review was carried out in the PUBMED, SCIELO and LILACS databases, with restrictions for the last 5 years with the following descriptors: composite resin; flowable; veneer silicone; composite resin injection; injection technique and injectable resin technique. Twelve articles were selected. Results: From a silicone mold, fluid composite resin is injected into the patient's teeth. After light-curing, this resin forms a faithful copy of a waxed model. Conclusion: Thanks to the technological evolution of the material, composite resin can be added in a single increment, enabling the technique. Aesthetics are satisfactory; however, some authors have reported problems with color stability over time. More studies need to be carried out to find out more about the longevity of these restorations.
