Comportamento mecânico e clínico de próteses monolíticas à base de zircônia: revisão de literatura

Abstract: Resumo Próteses fixas com infraestrutura de metal ou cerâmica apresentam muitas falhas devido ao lascamento da cerâmica vítrea de cobertura. Assim, próteses monolíticas produzidas com apenas um material foram desenvolvidas no intuito de diminuir estas falhas. Cerâmicas à base de zircônia tiveram suas propriedades ópticas modificadas para permitir a confecção de próteses monolíticas. Portanto, o objetivo deste estudo foi verificar através de uma revisão da literatura o comportamento mecânico e clínico das próte… Show more

“…The excellent mechanical properties of 1 st generation zirconia made it an attractive material to produce dental prostheses [3][4][5][6][7]. Pure zirconia has three main phases: monoclinic, tetragonal, and cubic, which are stable up to 1170 ° C, between 1170 ° C and 2370 ° C, and above 2370 ° C, respectively.…”

“…The monolithic all-ceramic prosthesis could result in lower chipping rates as the veneer layer is not present [3,7]. Thus, in order to improve the aesthetics of zirconia polycrystalline ceramic, the concentration of the alumina sintering additive was reduced, and the porosity was eliminated by sintering the ceramic at higher temperatures [12].…”
