Utilização da técnica de estratificação sobre uma cerâmica vítrea e sua eficácia na regularização de substratos com alteração de cor

RESUMO

Restabelecer o biomimetismo de dentes com alteração de cor é um grande desafio ao clínico. Contudo, atualmente, há uma grande gama de cerâmicas odontológicas com diferentes opacidades e translucidez que, em conjunto com os cimentos resinosos de diferentes cores, pode promover uma harmonização entre substratos de cores diferentes. Com isto, apresentaremos um trabalho realizado com uma cerâmica à base de silicato de lítio reforçado com dióxido de zircônia (Suprinity/VITA Zahnfabrik), cujo objetivo foi regularizar biomimeticamente as alterações de forma e cor no substrato do dente afetado.

Palavras-chave – Dissilicato de lítio reforçado com zircônia; Cor dentária; Cimentos odontológicos; Espessura de cerâmica.

ABSTRACT

Restoring altered tooth colors using biomimetics is a major clinical challenge. However, there is a wide range of dental ceramics nowadays with different opacities and translucencies that, together with resin cements of different colors can generate balance between many color substrates. This clinical case reports the use of a zirconium dioxide-reinforced lithim disilicate (Suprinity/VITA Zahnfabrik) with the aim to biomimetically control those changes affecting the shape and color of tooth substrates.

Key words – Zirconia-reinforced lithum disilicate; Tooth color; Luting cement; Ceramic thickness.
