Properties of two nickel-chromium crown-and-bridge alloys for porcelain veneering. 1977

E F Huget, and N Dvivedi, and H E Cosner

Composition, microstructure, mechanical properties, and alloy-porcelain bond strength of two proprietary nickel-chromium-based crown-and-bridge alloys were studied. The materials exhibited compositional as well as microstructural differences. Wiron-S was significantly stronger and harder than Microbond-NP. Microbond-NP yielded alloy-porcelain bond strength values comparable to those of precious alloy-porce-lain combinations.

UI	MeSH Term	Description	Entries
D009532	Nickel	A trace element with the atomic symbol Ni, atomic number 28, and atomic weight 58.69. It is a cofactor of the enzyme UREASE.
D001840	Dental Bonding	An adhesion procedure for orthodontic attachments, such as plastic DENTAL CROWNS. This process usually includes the application of an adhesive material (DENTAL CEMENTS) and letting it harden in-place by light or chemical curing.

D002858	Chromium Alloys	Specific alloys not less than 85% chromium and nickel or cobalt, with traces of either nickel or cobalt, molybdenum, and other substances. They are used in partial dentures, orthopedic implants, etc.	Chromium-Cobalt Alloys,Chromium-Nickel Alloys,Cobalt-Chromium Alloys,Nickel-Chromium Alloys,Alloys, Chromium,Alloys, Chromium-Cobalt,Alloys, Chromium-Nickel,Alloys, Cobalt-Chromium,Alloys, Nickel-Chromium,Chromium Cobalt Alloys,Chromium Nickel Alloys,Cobalt Chromium Alloys,Nickel Chromium Alloys
D003442	Crowns	A prosthetic restoration that reproduces the entire surface anatomy of the visible natural crown of a tooth. It may be partial (covering three or more surfaces of a tooth) or complete (covering all surfaces). It is made of gold or other metal, porcelain, or resin.

D003776	Dental Porcelain	A type of porcelain used in dental restorations, either jacket crowns or inlays, artificial teeth, or metal-ceramic crowns. It is essentially a mixture of particles of feldspar and quartz, the feldspar melting first and providing a glass matrix for the quartz. Dental porcelain is produced by mixing ceramic powder (a mixture of quartz, kaolin, pigments, opacifiers, a suitable flux, and other substances) with distilled water.
