Zirconia Primers Improve the Shear Bond Strength of Dental Zirconia.

Journal of Prosthodontics, 2019
PURPOSE Various resin cements and priming agents are available for adhesive luting of zirconia restorations. The purpose of this study was to investigate how cement type and priming protocol affect the shear bond strength on zirconia ceramics ...

Shear bond strength of four orthodontic bonding systems

American Journal of Orthodontics and Dentofacial Orthopedics, 1990
Recently new orthodontic bonding systems have been developed for attachment of brackets to the etched facial surfaces of teeth. Two of these new systems use bonding agents that contain solvents. It is claimed that this improves the polymerization of the unfilled resin primer and may increase bond strength.

Shear bond strength in porcelain-metal restorations

The Journal of Prosthetic Dentistry, 1980
1. The push test method showed higher shear bond strength values than the pull test method. 2. A bond strength of 4,500 to 6,000 psi between the dental stone and metal rod was eliminated in a waxed-rod test. Although the strength values were lower in waxed-rod tests, they were believed to be true shear bond strength values. 3.

Shear Strength of the Composite Bond to Etched Porcelain

Journal of Dental Research, 1987
The shear bond strength of composite resin to porcelain was investigated to optimize variables for bonding porcelain laminate veneers. Scanning electron microscopy was initially used to examine the surface configuration of porcelain prepared under various conditions.

Shear bond strength of an experimental composite bracket

Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 2013
The in vitro shear bond strength of MZ100 brackets (an experimental composite bracket developed by the Dental Biomaterial Laboratory at Boston University) and the effect of different treatment methods on these brackets were evaluated.As the bonding substrates, 80 Vitablocs® Mark II (Vident, Brea, CA, USA) were chosen.

The shear strength of enamel — composite bonds

Journal of Dentistry, 1977
Abstract The shear bond strengths of several commercial materials to etched enamel were evaluated using a modified punch test. An overall significant difference between the bond strength values for the composites was established. Increasing the punch speed was observed to have a detrimental effect on shear bond strength, and investigations into ...

Comparison of in vivo and in vitro shear bond strength

American Journal of Orthodontics and Dentofacial Orthopedics, 2003
Much of the research into composite adhesives suggests that these materials will deteriorate in the oral environment, but most of these claims are made on the basis of extrapolation from in vitro experiments; relatively little in vivo research has been conducted into the mechanical properties of composite adhesives.

Dentin shear bond strength of compomers and composites

Dental Materials, 2000
The aim of this study was to compare the shear bond strengths and fracture characteristics of two compomers bonded with a single step bonding agent with two modern composites, a microfil and hybrid, bonded with a fourth generation bonding agent.Freshly extracted human third molars were sectioned parallel to the occlusal surface to expose midcoronal ...

Shear strength of ceramic brackets bonded to porcelain

American Journal of Orthodontics and Dentofacial Orthopedics, 1994
The purpose of this study was to compare the bond strengths of three different adhesive systems when used alone and combined with a porcelain priming agent to bond ceramic brackets to porcelain surfaces. Sixty porcelain specimens were randomly assigned to the six different treatment groups.

Shear bond strengths of orthodontic plastic brackets

American Journal of Orthodontics and Dentofacial Orthopedics, 2000
The purpose of the present study was to evaluate the shear bond strengths of plastic brackets and the influences of the bracket filler contents on the bonding. The shear bond strengths of 4 plastic brackets (Spirit; Spirit MB; Clear Bracket; Aesthetic-Line) bonded to enamel with 4 orthodontic adhesives (Orthomite Superbond; System 1+; Transbond XT; and
