Adhesion promoters, their effect on the bond strength of metal brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 1995There are occasions where it is desired to increase the bond strengths of no-mix adhesives. Noncompliant patients and hypocalcified and fluorosed tooth enamel require higher bond strengths than usually obtained. It was the purpose of this investigation to study the effects of adhesion promoters to increase bond strengths.

An in vitro evaluation of a metal reinforced orthodontic ceramic bracket
American Journal of Orthodontics and Dentofacial Orthopedics, 1999The objectives of the present study were to measure and compare the bond strength and failure sites of a currently available ceramic bracket (Transcend 3M-Unitek) with the new metal reinforced ceramic bracket (Clarity 3M-Unitek) and to evaluate the amount of composite left on the tooth using the Adhesive Remnant Index in the teeth that were debonded ...

A comparison of shear bond strengths of metal and ceramic brackets
American Journal of Orthodontics and Dentofacial Orthopedics, 1988The study measures and compares shear bond strength data obtained from metal, ceramic, and ceramic-filled plastic brackets bonded to human incisor teeth with a heavily filled composite resin. The mean values for groups of different types of brackets were not statistically significant.

Effects of recycling on metallic direct-bond orthodontic brackets
American Journal of Orthodontics, 1980Recycling of metallic direct-bond orthodontic brackets is of current interest to the profession. The methods of three recycling companies (Esmadent, Ortho-Cycle, and Ortho-Bonding) as well as the author's flame method were examined for their effects on bracket base torque, slot width, and mechanical properties.

Er:YAG laser metal and ceramic bracket debonding
SPIE Proceedings, 2016The goal of the study was investigation of Er:YAG radiation (wavelength 2.94 μm) interaction with various metal and ceramic brackets and adhesive materials. The source of radiation was a free-running Er: YAG laser generating pulses with energy 280 mJ, 250 μs long and repetition rate 6 Hz (mean power 1.7 W).

[Comparative studies of fiberglass and metal brackets].
Fortschritte der Kieferorthopadie, 1989The demand by patients considered for better esthetics during treatment should be seriously considered. With the introduction of fiberglass brackets one has tried to solve that problem. The purpose of this investigation was: 1. a microscopic examination of the slots of these fiberglass brackets after various periods of wearing; 2.

In vitro study of adhesive fixation of metal brackets
Stomatology for All / International Dental reviewThe study investigated the micropermeability of the tooth-adhesive-bracket complex when using metal self-ligating and ligature brackets with «CompoFix Ortho» (Russia) and «Transbond XT» (USA) adhesives. Forty premolars removed for orthodontic reasons and free of caries were used.
