AIM The aim of this study was to evaluate the effect of recasting base metal alloy on the metal-ceramic bond strength. MATERIALS AND METHODS A total of 60 test samples were prepared from new and recast nickel-chromium alloy and divided into six groups. In group A0, test samples were prepared from 100% new alloy. Groups A1, A2, A3, A4, and A5 were prepared from 50% new alloy and 50% casting re...

Although an all-ceramic restoration is increasingly in use in dentistry, a conventional metal ceramic restoration is still considered to be a gold standard. However, with increasing demand in esthetics and advances in ceramic technology, future of metal ceramic restoration has been less certain, necessitating additional qualities in terms of superior esthetics and easy fabrication. A ceramic-pr...

BACKGROUND/AIM Metal-ceramic bond strength and alloys' elastic modulus clearly determine the potential of alloy application, because the ceramic integrity during mastication depends on these two characteristics. The aim of this study was to evaluate metal-ceramic bond strenght and elastic modulus of cobalt-chromium alloys in making porcelain-fused-to-metal restorations, regarding the applicatio...

We proposed using metal-insulator-metal (MIM) nanorod arrays for subwavelength imaging to improve the resolution based on the notable ability of field confinement of the MIM nanorods. The field distribution of a single Au-SiO(2)-Au nanorod, coupling between two nanorods and image transfer of shaped dipole sources through nanorod arrays were investigated by using the finite-difference time-domai...

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

STATEMENT OF PROBLEM Although the esthetic outcome of a collarless metal ceramic restoration is superior to that of a restoration with a metal margin, its mechanical strength has not been evaluated. PURPOSE The purpose of this study was to evaluate and compare the fracture resistance of metal ceramic restorations with metal margins to that of metal ceramic restorations with circumferential po...

Different techniques for fabricating long-range plasmonic metallo-dielectric waveguides are discussed. The approaches depend strongly on the material system in use. Specific results are presented for SU8 and PDMS.

Lightweight ceramic-metal combinations are one option for advanced vehicle and other structural applications. These structures can require the fabrication of large area arrays of ceramic tiles on a metallic backing. However, the process of fabricating a combination of lightweight ceramics and metals is complicated by the need to bond these very dissimilar materials together. For severe applicat...
