Y-TZP Ceramics: Key Concepts for Clinical Application

Abstract: Compared to conventional ceramic systems, Yttrium-stabilized tetragonal zirconia (Y-TZP) ceramics have some superior mechanical properties, ensuring a broad application in dentistry. The current study aimed to present relevant information about Y-TZP ceramics gathered from peer-reviewed papers. A search of the English language peer-reviewed literature was conducted using the PubMed database between 1998 and 2008. Articles that did not focus exclusively on the clinical application of Y-TZP ceramic restorations … Show more

“…Grãos cúbicos são muito maiores que os grãos monoclínicos e tetragonais, possuem elevada resistência flexural e dureza, porém são indesejados, pois desestabilizam os cristais adjacentes a ele. 2,15 Neste estudo não foi possível diferenciar o formato específico dos cristais destas fases cristalinas, mas foi possível determinar o tamanho deles, que variaram de 0,1 a 0,5 µm. Foram observados formações de aglomerados ou estruturas compactas, dependendo do material.…”

“…4 These ceramics have a small crystalline phase compared with the older types (silica-based ceramics); as a result, the commonly used methods to enhance the bond strength, such as hydrofluoric acid etching are not effective for roughening of surface, increasing the wettability and increasing the required surface for mechanical interlocking and use of silane before the application of resin cement due to the absence of silica are not much effective. 5,6 Moreover, since zirconia has a neutral surface, 7 it has a low potential for forming a chemical bond, and this compromises the union of zirconia substrate with cement. 8 In other words,…”
