Faceta direta de resina composta utilizando pigmentos opacificadores para reabilitação estética anterior de dente escurecido: relato de caso

Abstract

The aesthetic treatment of discolored teeth is a major challenge in Restorative Dentistry. Among the possibilities and indications for the rehabilitation of such elements, the aesthetic results obtained with composite resins are widely known and, respecting the physicochemical characteristics of the material and execution techniques, present predictable results in clinical terms. In this sense, the use of layering techniques with composite resin associated with the use of opacifying pigments makes it possible to restore teeth with severe tooth discoloration using a direct technique. Thus, the present work presents a clinical case of a direct composite resin veneer for the aesthetic treatment of a discolored tooth, using an association of three opacifying pigments. Male patient, 54 years old, attended with severe discoloration of tooth 21, report of dental trauma, endodontic treatment and contraindication of a new non-vital bleaching protocol, being suggested as a treatment plan, direct restoration with composite resin. To make the direct resin veneer, a mixture of three opacifiers was used in fluid consistency and layering with layers of translucent resin for the palatal base, opaque dentin resin and translucent achromatic resin for the enamel. As a result, the function and effectiveness of using the association of opacifying pigments in the resolution of the case was verified. A reassessment wasperformed after 30 days and 7 months of the restorative procedure, where the color stability of the restoration was verified. It was concluded, therefore, that the use of the composite resin layering technique associated with the use of opacifying pigments brings aesthetic and proven results through a direct technique, performed in a single clinical session and with high predictability.
