Production of zirconia-based ceramic fibers using viscose material

Sintering properties of zirconia-based ceramic composite

This study examines the effects of different ZrB2 content on various mechanical properties and electrical conductivity of ZrB2/Y-TZP composite. Composites with ZrB2 content of up to 20 wt-% were particularly beneficial at the lower sintering temperature range by achieving greater densification and better hardness than Y-TZP monolith. In contrast to the trends estimated from rule of mixture, the...

The Zirconia: a new dental ceramic material. An overview.

Yttrium tetragonal Zirconia polycrystals (Y-TZP) based systems are the more recent addition in to the high-strength all-ceramic systems that are used for crowns and fixed partial dentures. CAD/CAM produced Y-TZP based systems are being used and are said to be in demand in the aesthetic zone and in stress bearing regions as well. This systematic overview covers results of recent scientific studi...

Somaraj V: Esthetic Rehabilitation using Zirconia-Based All-Ceramic Crown

The dental practice is not only about prevention and treatment of oral diseases but also the fulfillment of demands of all who seek oral care, of which esthetics weighs more importance than any. To achieve excellence in the delivery of dental care, dentists rely on the vast array of modern advances in dental materials and restoration fabrication technologies. Need for more esthetical, metal-fre...

The Optical Effect of Zirconia Background , Ceramic Thickness , and Cement on All - Ceramic Material

Effect of Zirconia Thickness on the Tensile Stress of Zirconia Based All-Ceramic Restorations

Introduction: The purpose of the presented study was to evaluate the effect of zirconia thickness on the tensile stress of zirconia based all-ceramic restorations. Methods: Twenty zirconia disks with 10mm diameter were prepared in two groups using CAD/CAM system. The thickness of zirconia was 0.5mm in first group and 0.3mm in second group. After sintering, 0.4mm glass ceramic porcelain was appl...
