Substituição de restaurações de amálgama por resina composta - estado de arte e relato de caso

Abstract

INTRODUCTION: Comprises the evolution of restorative materials and adhesion in Dentistry, transformed of choice for restorations of posterior teeth. With resins, it is possible to perform less invasive preparations, obtain excellent results and, due to the biomechanical behavior similar to the tooth structure, the risk of fracture of the tooth structure is lower when compared to extensive esthetics. Thus, the replacement of extensive amalgam restorations with composite resin is much discussed. OBJECTIVES: The objective of this work is to carry out and report a case of replacement of amalgam restorations by composite resin, as well as to relate the main scientific findings related to the topic. METHODOLOGY: A literature review was carried out in order to search for the main ones related to the replacement of amalgam restorations with composite resin, as well as the biomechanical behavior of each material. The clinical case was performed after signing the Free and Informed Consent Form. The procedure continued with the removal of the old restorations under absolute isolation, using the universal adhesive resin system (Single Bond Universal, 3M ESPE) and the Filtek Z350 XT nanoparticulate resin system (3M ESPE). RESULTS: Many controversies regarding the use and replacement of amalgam are in force, and it is up to the clinician to carefully analyze each case analyzed for decision making. The execution of the clinical treatment made it possible to replace the aesthetics of the patient, the health of the restorations, caseabilization or adequate inclusion. FINAL CONSIDERATIONS Restoration replacement, DERmatization: aesthetic behavior and better biomechanics for restorations, with good prognosis and composite alterations.
