Low temperature degradation of a Y-TZP dental ceramic.
Bars of Y-TZP ceramic for dental restorations were subjected to hydrothermal degradation via in vitro exposure to water steam at 140°C for 7 days. X-ray diffraction, atomic force microscopy and scanning electron microscopy techniques were applied to observe and quantify the tetragonal-monoclinic (t-m) phase transformation associated with the process. Nanoindentation was used to assess the ceram...

متن کاملCad/cam Y-tzp–based Restorations
Tel: 504-619-8607 Fax: 504-619-8741 E-mail: [email protected] Prospective clinical studies are evaluating the long-term success of Y-TZP–based all-ceramic FPDs. Y-TZP–based infrastructures for crowns and FPDs present favorable physical, mechanical, and optical properties. Some Y-TZP–based restorative systems use CAD/CAM technology. Nevertheless, technicians should be able to employ traditiona...
متن کاملBonding of Y-TZP to dentin: effects of Y-TZP surface conditioning, resin cement type, and aging.
PURPOSE To evaluate the effects of two surface treatments, aging, and two resin cements on shear bond strength between dentin and yttrium-stabilized tetragonal zirconia polycrystal ceramic (Y-TZP). MATERIALS AND METHODS Eighty human molars were embedded in acrylic resin and sectioned 3 mm below the occlusal plane. These teeth and 80 cylindrical Y-TZP specimens (height, 4 mm; diameter, 3.4 mm)...
متن کاملDeposition of Crystalline Hydroxyapatite Nanoparticles on Y-TZP Ceramic: A Potential Solution to Enhance Bonding Characteristics of Y-TZP Ceramics
Objectives Many advantages have been attributed to dental zirconia ceramics in terms of mechanical and physical properties; however, the bonding ability of this material to dental structure and/or veneering ceramics has always been a matter of concern. On the other hand, hydroxyapatite (HA) shows excellent biocompatibility and good bonding ability to tooth structure, with mechanically unstable ...
