OBJECTIVE To assess the 5-year survival of metal-ceramic and all-ceramic tooth-supported single crowns (SCs) and to describe the incidence of biological, technical and esthetic complications. METHODS Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials (CENTRAL) searches (2006-2013) were performed for clinical studies focusing on tooth-supported fixed dental prostheses (FD...

The hydrogen solubility in zirconia (yttria stabilized zirconia, YSZ) using a tritium imaging plate (IP) technique has been measured in a temperature region ranging from 673K to 973K. The tritium distribution in the zirconia specimens was nearly uniform suggesting an equilibrated dissolution. The hydrogen solubility in specimens were rather low (around ppm or below) and showed Arrhenius type te...

Porous ceramics have separation/collection (open pore) and heat-shielding/sound-absorbing (closed characteristics not found in conventional dense ceramics, increasing their industrial importance along with ceramics. Reticulated porous a type of ceramic material, are characterized by three-dimensional network structure having high porosity permeability. Although there been numerous studies zirco...

OBJECTIVES To investigate the effect of air-drying pressure during ceramic primer coating on zirconia/resin bonding and the surface characteristics of the primed zirconia. METHODS Two ceramic primers (Clearfil Ceramic Primer, CCP, Kuraray Medical Inc. and Z-Prime Plus, ZPP, Bisco Inc.) were applied on the surface of air-abraded zirconia (Katana zirconia, Noritake) and dried at 4 different air...

STATEMENT OF PROBLEM Successful long-term bonding to zirconia ceramic remains a challenge, requiring special cements and surface roughening by airborne-particle abrasion, which might negatively affect the ceramic. PURPOSE The purpose of this study was to evaluate the shear bond strength (SBS) of composite resin cylinders to a modified zirconia surface using different luting techniques after t...

Introduction: The conditioning procedures for glass-based ceramic restorations before adhesive cementation are generally recognized. In the case of polycrystalline ceramics, which include zirconium oxide, there is still no standardized protocol. aim this work was to present methods surface oxide fixed dentures. new generation high translucency zirconia has been also considered. Material and met...

CONTEXT Marginal discrepancy influenced by the choice of processing material used for the ceramic laminate veneers needs to be explored further for better clinical application. AIMS This study aimed to evaluate the amount of cervical and incisal marginal discrepancy associated with different ceramic laminate veneering materials. SETTINGS AND DESIGN This was an experimental, single-blinded, ...

The ballistic impact performance of nanocrystalline zirconia-toughened alumina (nZTA) ceramics, comprising 15 wt% nano-yttria-stabilised zirconia in a sub-micron matrix, have been studied through depth penetration tests and compared to the results for monolithic alumina. resistance each material was evaluated by fitting against thickness ceramic targets. These show that, despite micro-Raman ana...

An experimental study of the rotary ultrasonic drilling of ceramics is first presented. The influence of different process parameters on the material removal rate for machining of magnesia stabilized zirconia is examined. Then a mechanistic approach to modeling the material removal rate during rotary ultrasonic drilling of ceramics is proposed and applied to predicting the material removal rate...

Nano-zirconia is commonly used in dentistry as a framework material over which feldspathic porcelain layered to form an aesthetic and strong bi-layered restoration. Sufficient bonding strength between zirconia frameworks veneering porcelains crucial for the longevity of zirconia-based dental restorations. This study aims determine shear bond (SBS) colloidal-processed slip-casted novel nano-zirc...
