Restaurações cerâmicas delgadas sobre dentes sem preparo em diferentes regiões dos arcos dentais. Relato de 2 casos clínicos

Abstract

As reforçadas propriedades intrínsecas dos materiais cerâmicos, associados à adesão resinosa fundamentam a desenvoltura de técnicas restauradoras mais simplificadas, conservadoras e sem a necessidade de preparo dental prévio seja em dentição anterior ou posterior. Assim sendo, o trabalho tem como objetivo apresentar dois casos clínicos os quais abordaram a confecção de restaurações delgadas em dissilicato de lítio cimentadas sobre diferentes áreas dos arcos dentários, enfatizando o mesmo protocolo clínico, ou seja, ausência de preparos dentais e consequentemente a cimentação resinosa adesiva das restaurações. Caso Clínico 1: laminados cerâmicos nos elementos 13, 12, 11, 21, 22 e 23; Caso Clínico 2: facetas delgadas sobre os elementos 34, 35, 36 e 37. Ambos os casos clínicos com 1 ano de acompanhamento após a cimentação das restaurações. Conclui-se que houve a recuperação da estética e da função em ambos os casos apresentados e a confiabilidade e o sucesso em longo prazo do protocolo clínico descrito estão diretamente relacionados ao substrato dentário, aos fatores de adesividade dos materiais e as propriedades intrínsecas das cerâmicas.
