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...
متن کاملAlumina and Zirconia Ceramic for Orthopaedic and Dental Devices
Ceramic materials are made of an inorganic non-metallic oxide. Usually ceramics are divided into two groups: silicon ceramics and aluminous ceramics. Ceramics are also divided into crystalline and non-crystalline depending on inner molecular organization. Depending on their in vivo behaviour, ceramics are classified as bioresorbable, bioreactive or bioinert. Alumina and zirconia are bioinert ce...
متن کاملThe 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...
متن کاملVaried simulation-based stress analyses on zirconia all-ceramic crowns
The development of high-strength ceramics and its use in posterior areas has been a field of constant investigation. The performance of all-ceramic molar crowns fabricated with new CAD/CAM techniques is a subject of interest. The studies available in literature focused on the analysis of all-ceramic restorations failures, investigating several parameters involved on the tooth structure. The goa...
متن کاملClinical marginal and internal gaps of zirconia all-ceramic crowns.
PURPOSE Marginal and internal gaps of NobelProcera crown zirconia were clinically evaluated using silicone materials. MATERIALS AND METHODS Ninety-one crowns were examined before final cementation, and white and black silicone materials were used to record the marginal and internal fit. The silicone materials were sectioned bucco-lingually and mesio-distally, and the thickness of the silicone...
