Shear strength of orthodontic direct-bonding adhesives

American Journal of Orthodontics, 1976
A total of 210 double-width stainless steel edgewise brackets with retentive lip bases were bonded to bovine incisors with seven commercially available direct-bonding materials. Ten samples for each of the seven direct-bonding materials were tested for shear strength using the Instron Universal Testing Instrument. The samples were tested after 1 day, 1

Shear bond strength of six restorative materials

Journal of Clinical Pediatric Dentistry, 2001
The purpose of this study was to determine and compare the shear bond strength of a conventional glassionomer cement, a resin modified glass-ionomer, a composite resin and three compomer restorative materials. Dentin of the occlusal surfaces from sixty extracted human permanent molars were prepared for shear bond strength testing.

Shearing strengths of recycled direct-bonding brackets

American Journal of Orthodontics, 1982
One hundred twenty freshly extracted human incisor teeth were bonded with several different brands of direct-bonding brackets and tested for retention prior to and after recycling of the brackets by two different commercially available methods. Measurements of shearing strengths were performed to observe any possible changes in the retentive properties

The effect of saliva on shear bond strengths of hydrophilic bonding systems

American Journal of Orthodontics and Dentofacial Orthopedics, 2001
Failure of orthodontic bonded attachments and brackets is mostly attributed to contamination of the enamel surface. To overcome this problem, materials have been developed that purportedly overcome the moisture and contaminants present in the oral environment.

Bonding amalgam to enamel: Shear bond strength and SEM morphology

The Journal of Prosthetic Dentistry, 2001
Most studies of amalgam bonding have used dentin as the substrate. There is little data on bonding to enamel.This study evaluated the shear bond strength of amalgam to enamel with the use of 3 resin cements, 1 resin-modified glass ionomer lining cement, and 2 dentin bonding agents.Sixty bovine teeth were trimmed to expose a flat enamel surface and ...

The Effect of Fatigue on the Shear Bond Strength of Resin Bonded to Porcelain

Journal of Prosthodontics, 1993
Purpose The objective of this study was to determine whether fatigue cycling affects the shear bond strength of a resin that is initially strongly bonded to porcelain.Materials and Methods Thirty‐five disks of a feldspathic/leucite porcelain were fired on a phosphate‐bonded investment material.

Shear bond strength of techniques for bonding esthetic veneers to metal

The Journal of Prosthetic Dentistry, 1999
New composites with improved qualities have been introduced to the dental profession as alternatives to porcelain. There is concern about the strength and reliability of new metal-resin bonding systems when these composites are used as esthetic veneers over metal frameworks.This in vitro study compared the shear bond strength of 2 metal-resin bonding ...

Evaluation of the shear bond strength of resin cement to Y-TZP ceramic after different surface treatments.

Scanning, 2014
The purpose of this study was to evaluate the effect of various surface treatments on the shear bond strength of Y-TZP (Yttria-Tetragonal Zirconia Polycrystal) ceramics with zirconia primer and two different resin cements both containing 10 ...

Shear bond strength of a new dentin bonding restorative system

Dental Materials, 1988
Abstract A new visible light-cured composite restorative resin, Lumifor, used in conjunction with a dentin bonding agent, Gluma, has recently become commercially available in Europe. The objective of this study was to determine the shear bond strength of the restorative system to dentin.
