Retention strength of cobalt-chromium vs nickel-chromium titanium vs Cp titanium in a cast framework association of removable partial overdenture
(2011-05-01)
Aim: There is little information considering the framework association between cast clasps and attachments. The aim of this study was to evaluate the retention strength of frameworks match circumferential clasps and extra ...
Effect of cantilever length and framework alloy on the stress distribution of mandibular-cantilevered implant-supported prostheses
(Wiley-Blackwell Publishing, Inc, 2009-07-01)
The purpose of this in vitro study was to analyze the stress distribution on components of a mandibular-cantilevered implant-supported prosthesis with frameworks cast in cobalt-chromium (Co-Cr) or palladium-silver (Pd-Ag) ...
Shear bond strength of aesthetic materials bonded to Ni-Cr alloy
(Elsevier B.V., 2003-03-01)
Objectives. This study was undertaken to evaluate the shear bond strength of four materials used as aesthetic material bonded to Ni-Cr alloy.Methods. Sixty-eight alloy discs were prepared and divided equally into four ...
Biomedical Ti-Mo Alloys with Surface Machined and Modified by Laser Beam: Biomechanical, Histological, and Histometric Analysis in Rabbits
(2013-06-01)
Purpose: In vivo bone response was assessed by removal torque, hystological and histometrical analysis on a recently developed biomedical Ti-15Mo alloy, after surface modification by laser beam irradiation, installed in ...
A study of histological responses from Ti-6Al-7Nb alloy dental implants with and without plasma-sprayed hydroxyapatite coating in dogs
(Springer, 2001-03-01)
Titanium alloys are hoped to be used much more for applications as implant materials in the medical and dental fields because of their basic properties, such as biocompatibility, corrosion resistance and specific strength ...
Influência do escoamento estático (CREEP) na dureza do amálgama. Efeito de ligas e regióes de medida.
(1990-05-01)
The authors studied the CREEP of 5 amalgam alloys (1 conventional and 4 with high cooper) by the application os static load of 36 MPa in 478 mm specimens, 7 days old. After CREEP test, the samples were included in acrylic ...
A Quality Assessment of Titanium Castings Produced in an Experimental Short-Heating-Cycle Investment
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2014)
Influence of acid-etching and ceramic primers on the repair of a glass ceramic
(2012-03-01)
The objective of this study was to evaluate the influence of different primers on the microtensile bond strength (μT BS) between a feldspathic ceramic and two composites. Forty blocks (6.0 × 6.0 × 5.0 mm 3) were prepared ...
Histological analysis of the osseointegration of Ti-30Ta dental implants after surface treatment
(2013-02-28)
Metallic biomaterials are used to reinforce or to restore the form and function of hard tissues. Implants and prosthesis are used to replace shoulders, knees, hips and teeth. When these materials are inserted in bone several ...
