Effect of metal type and surface treatment on in vitro tensile strength of copings cemented to minimally retentive preparations

Bond Strength of Resin Cements to Co-Cr and Ni-Cr Metal Alloys Using Adhesive Primers

“…As the basic chemistry and setting reactions of RelyX Unicem are close to characteristics of zinc polycarboxilate and glass ionomer cements, it is possible to speculate that good adhesion on metal alloy surfaces can be obtained by cementation with RelyX Unicem. 15,24,25 The bond strengths of most of experimental groups to CoCr metal alloy were higher than to Ni-Cr, except for RelyX Unicem, Panavia F 2.0 and LinkMax + Metal Primer II. The bonding between casting alloy surface and adhesive resin composite cement is created by micromechanical retention promoted by sandblasting 9,21 and the layer of chromium oxides that is easily created on the casting Co-Cr metal surface.…”

“…[9][10][11][12] In an attempt to improve the bonding of composites to alloys, electrolytic etching, chemical etchants, adhesive primer (AP) application, and silica coating methods and techniques for surface treatment of base metal alloys have been proposed. [8][9][10][13][14][15][16][17][18][19][20][21][22] Alloy primers contain monomers capable of chemically…”

“…[9][10][11][12] In an attempt to improve the bonding of composites to alloys, electrolytic etching, chemical etchants, adhesive primer (AP) application, and silica coating methods and techniques for surface treatment of base metal alloys have been proposed. [8][9][10][13][14][15][16][17][18][19][20][21][22] Alloy primers contain monomers capable of chemically bonding to noble cast dental alloys; however, for non-precious alloys, the adhesion reactions are little known, and clinical indications remain controversial. [17][18][19][20] The purpose of this study was to evaluate the effects of APs on shear bond strength of dual-cured resin cementing systems to Co-Cr and Ni-Cr cast dental alloys.…”

Comparison of Bond Strength of Commercially Pure Titanium and Nickel Chromium Alloy With Three Different Luting Cements: An in-Vitro Study

“…5 The surfaces can be airborne-particle abraded to provide for a clean and roughened surface prior to cementation. 1 Studies conducted by Egoshi et al, 9 showed cement bond strength was found to be high, especially after airborneparticle abrasion to base metal alloys. According to previous studies.…”

“…1 Bonding between a metal framework and a luting cement is important to withstand the varied changes in the oral environment. 2 subjected to a combination of masticatory forces repeated over a period of time.…”
