Resumo
Diante do surgimento de cerâmicas vítreas reforçadas com zircônia, das vantagens estéticas e mecânicas atribuídas a esse material, faz-se necessário avaliar sua eficácia na confecção de restaurações anteriores, desse modo, o objetivo deste trabalho foi relatar um caso clínico de reabilitação estética anterior usando cerâmicas vítreas reforçadas com zircônia. Paciente do gênero masculino, 30 anos, compareceu à clínica de Prótese Fixa da Faculdade de Odontologia de Araçatuba – FOA/UNESP insatisfeito com a aparência do seu sorriso. No exame clínico, foi constatado a presença de facetas em resina composta nos dentes 11, 12, 21, 22, as quais apresentavam estética insatisfatória devido grande alteração de cor, contornos e formatos dentários desproporcionais. O tratamento proposto foi a confecção de duas coroas totais (elementos 11 e 21), duas facetas (elementos 12 e 22) e duas lentes de contato (elementos 13 e 23). As peças definitivas foram confeccionadas utilizando a cerâmica de silicato de lítio reforçada com zircônia. Os passos clínicos realizados foram: enceramento diagnóstico, mock up, remoção das restaurações em resina composta, preparo dos elementos, moldagem com silicone de adição, provisórios, confecção das peças pelo sistema CAD/CAM, provas e ajustes, cimentação resinosa com o sistema Variolink® N (Ivoclar Vivadent), ajuste oclusal e orientação de higienização. Conclui-se que reabilitação oral anterior com a utilização da cerâmica silicato de lítio reforçado por zircônia é uma alternativa de tratamento eficiente, capaz de proporcionar resultado esteticamente favorável, harmônico e funcional para o sorriso do paciente.
In front of the emergence of glass ceramics reinforced with zirconia, he aesthetic and mechanical advantages attributed to this material, it is necessary to evaluate its effectiveness in the manufacture of previous restorations. Thus, this work aims to report a clinical case of previous aesthetic rehabilitation using glass ceramics reinforced with zirconia. 30-year-old male patient attended the clinic of Prostheses the University of Odontology of Araçatuba – FOA/UNESP dissatisfied with the appearance of his smile. In the clinical exam, it was found the presence of composite resin veneers on teeth 11, 12, 21, 22; which presented unsatisfactory aesthetics due to major color changes, outlines and disproportionate dental shapes. The treatment proposed was the making of two full crowns (elements 11 and 21), two facets (elements 12 and 22) and two contact lenses (elements 13 and 23). The definitive pieces were made using zirconia-reinforced lithium silicate ceramics. The clinical steps taken were: diagnostic waxing, mock up, removal of composite resin restorations, preparation of the elements, molding with additional silicone, provisionals, making of the pieces using the CAD / CAM system, tests and adjustments, resin cementation with the Variolink® N system (Ivoclar Vivadent) , occlusal adjustment and hygiene guidance. It is concluded that previous oral rehabilitation using zircon-reinforced lithium silicate ceramics is an efficiente alternative treatment and capable to provide aesthetically favorable, harmonic and functional result for the patient's smile.
