Metal‐Ceramic Alloys in Dentistry: A Review
Journal of Prosthodontics, 2009Abstract Purpose: The purpose of this article is to review basic information about the alloys used for fabricating metal‐ceramic restorations in dentistry. Their compositions, properties, advantages, and disadvantages are presented and compared. In addition to reviewing traditional noble‐metal and base‐metal metal‐ceramic alloys, titanium and gold ...

Properties of test metal ceramic titanium alloys
The Journal of Prosthetic Dentistry, 1992Four test alloys were prepared using a high frequency centrifugal casting machine and a ceramic crucible for the development of titanium bonding alloys that can be cast in the ordinary atmosphere. Of these alloys, 10.06% Ti, 78.79% Ni, 9.02% Pd, 1.77% Sn and 9.91% Ti, 78.56% Ni, 9.07% Pd, 1.86% Sn, 0.65% Ir could be cast by the conventional high ...

Characterization of two ceramic-base-metal alloys
The Journal of Prosthetic Dentistry, 1978Compositions, microstructures, properties, and heat treatment characteristics of two ceramic-base-metal alloys were studied. The materials displayed significant compositional and structural differences. Both alloys were strengthened by precipitation hardening.

Metal Ceramic Bond After Multiple Castings of Base Metal Alloy
The Journal of Prosthetic Dentistry, 2009Remelting previously cast metal can produce a critical change in metal-oxide composition at the dental alloy surface.The purpose of this study was to evaluate the effect of multiple castings on bonding of a single selected base metal and a dental ceramic, and to compare results from shear bond and 3-point-bending tests.Three groups of dental alloy ...

Bonding of dental porcelain to ceramic-metal alloys
The Journal of Prosthetic Dentistry, 1987The bond strength of porcelain to the four gold alloys and the three nonprecious alloys was tested with a simplified pull test method, having wide test surfaces. The tests showed that all gold alloys tested were suitable for fusing porcelain. The bond strength in nonprecious alloys was somewhat lower and the location of the fracture lines was more ...

Fit of titanium and a base metal alloy metal-ceramic crown
The Journal of Prosthetic Dentistry, 2000Titanium has been widely used in dental implantology. However, problems remain for use of titanium in prosthodontics.This study evaluated the marginal and inner fit of metal-ceramic restorations and frameworks made with a nickel-chromium alloy (Remanium CS) and a commercially pure titanium (Rematitan).

Alloys for Metal-Ceramic Restorations
Dental Update, 2005The requirements of a metal-ceramic dental restoration consisting of a rigid substrate, which supports an aesthetic veneer, are assessed. The contemporary, cast, bonding alloys that have good track records as substrates are categorized and their properties are compared. Several alternatives to cast metals are considered.

Noble Metal Alloys for Metal-Ceramic Restorations
Dental Clinics of North America, 1985A review of the comparative characteristics and properties of noble metal alloys used for metal-ceramic restorations has been presented. Selection of an alloy for one's practice should be based on long-term clinical data, physical properties, esthetic potential, and laboratory data on metal-ceramic bond strength and thermal compatibility with ...

Mechanical properties of metal-ceramic alloys at high temperature
Dental Materials, 1990Four alloys used for the construction of porcelain-fused-to-metal restorations were tested at high temperatures (1000 degrees C) so that loss of properties could be ascertained. In addition, thin flat plates of metal (30 x 11 x 1 mm) with a 9-mm recess and a metal thickness of 0.35 mm were processed for porcelain application and distortion measured at ...

Metal‐Ceramic Interface Evaluation of a Gold‐Infiltrated Alloy
Journal of Prosthodontics, 2009Abstract Purpose: The success of metal‐ceramic systems partially depends on the formation of a stable bond between metal and porcelain. The purpose of this study was to investigate the porcelain/metal interface and the mechanism of interfacial bonding in a gold‐infiltrated alloy (Captek).
