Influence of thermal and mechanical cycling on the flexural strength of ceramics with titanium or gold alloy frameworks
(2008-03-01)
Objectives: The aim of this study was to evaluate the effect of thermal and mechanical cycling alone or in combination, on the flexural strength of ceramic and metallic frameworks cast in gold alloy or titanium. Methods: ...
Investigation of the metal/porcelain interface in LASER-welded Ni-Cr-Mo alloy
(2009-07-22)
The interface formed between the metal and the porcelain of laser-welded Ni-Cr-Mo alloy was studied on a metallurgical basis. The characterization was carried out by using optical microscope, electron scan microscopy and ...
Correlation between metal-ceramic bond strength and coefficient of linear thermal expansion difference
(Faculdade De Odontologia De Bauru - USP, 2009)
The purpose of this study was to evaluate the metal-ceramic bond strength (MCBS) of 6 metal-ceramic pairs (2 Ni-Cr alloys and 1 Pd-Ag alloy with 2 dental ceramics) and correlate the MCBS values with the differences between ...

The effect of a bonding agent and thermo-mechanical cycling on the bond strength of a glass-ceramic to gold and cobalt-chromium alloys
(2014-01-01)
To evaluate the effects of bonding agent and thermo-mechanical cycling on the flexural bond strength of a gold and cobalt-chromium alloy to a feldspathic ceramic. Sixty-four metal bars were fused (3 × 25 × 0.5 mm3): 32 ...
Does the casting mode influence microstructure, fracture and properties of different metal ceramic alloys?
(SOCIEDADE BRASILEIRA DE PESQUISA ODONTOLOGICASAO PAULO, 2012)
The aim of the present study was to evaluate the tensile strength, elongation, microhardness, microstructure and fracture pattern of various metal ceramic alloys cast under different casting conditions. Two Ni-Cr alloys, ...
Opaque Layer Firing Temperature and Aging Effect on the Flexural Strength of Ceramic Fused to Cobalt-Chromium Alloy
(Wiley-Blackwell, 2010-08-01)
Purpose: To evaluate the effect of the opaque layer firing temperature and mechanical and thermal cycling on the flexural strength of a ceramic fused to commercial cobalt-chromium alloy (Co-Cr). The hypotheses were that ...
Shear bond strengths of a ceramic system to alternative metal alloys
(Mosby, Inc, 2005-01-01)
Statement of problem. The success of metal-ceramic restorations is influenced by the compatibility between base metal alloys and porcelains. Although porcelain manufacturers recommend their own metal systems as the most ...
Evaluation of the shear bond strength of the union between two CoCr-alloys and a dental ceramic
(Journal Of Applied Oral Science : Revista Fob, 2004)
Introduction: Based on the importance of the integrity of the metal/ceramic interface, the purpose of this work was to evaluate the shear bond strength of the metal-ceramic union of two Co-Cr alloys (Wirobond C, Bego; ...
