Gelcasting as a Novel Processing Route to Fabricate Partially Stabilized Zirconia Ceramic Bodies
Bioinert ceramics, like alumina and zirconia are used mainly for replacements of bones, hip joints and for dental implants. Partially stabilized zirconia ceramics (PSZ or TZP with 3 mol.% or 5 wt.% Y2O3), appear as perspective bioinert ceramics because of their high strength and corrosion resistance. In order to fabricate complex shapes, it is essential to use a near ...
متن کاملZirconia Crown as Single Unit Tooth Restoration: A Literature Review.
Ceramics has become increasingly popular as a dental restorative material because of its superior esthetics, as well as its inertness and biocompatibility. Among dental ceramics, zirconia is used as a dental biomaterial and it is the material of choice in contemporary restorative dentistry. Zirconia ceramics has both clinical popularity and success due to its outstanding mechanical properties a...
متن کاملY-TZP ceramic processing from coprecipitated powders: a comparative study with three commercial dental ceramics.
OBJECTIVES (1) To synthesize 3mol% yttria-stabilized zirconia (3Y-TZP) powders via coprecipitation route, (2) to obtain zirconia ceramic specimens, analyze surface characteristics, and mechanical properties, and (3) to compare the processed material with three reinforced dental ceramics. METHODS A coprecipitation route was used to synthesize a 3mol% yttria-stabilized zirconia ceramic processe...
متن کاملEffects of a convenient silica-coating treatment on shear bond strengths of porcelain
Significant progress has been achieved in ceramics since the late 1990s1-4). In particular, new technological innovations such as heat-pressed5,6), injection-molded7), slip-cast8), and glass-infiltrated ceramics9-11) have widened the use of ceramics in prosthetic and operative dentistry. However, properties such as brittleness limit their use in applications such as fixed partial dentures. Sinc...
متن کاملApplication of Zirconia in Dentistry: Biological, Mechanical and Optical Considerations
With the aim of replacing the infrastructure of metallic dental prostheses, structural ceramics have been improved and have become increasingly more popular in dentistry. Among the dental ceramics, zirconia has emerged as a versatile and promising material because of its biological, mechanical and optical properties, which has certainly accelerated its routine use in CAD/CAM technology for diff...
