Bioactive Plasma Coatings on Orthodontic Brackets: In Vitro Metal Ion Release and Cytotoxicity [PDF]

Coatings, 2021
The metal ion release characteristics and biocompatibility of meta-based materials are key factors that influence their use in orthodontics. Although stainless steel-based alloys have gained much interest and use due to their mechanical properties and ...

Shear bond strength of metal brackets compared with a new ceramic bracket

American Journal of Orthodontics and Dentofacial Orthopedics, 1988
One hundred twenty bovine teeth were bonded with two types of metal brackets and a new ceramic bracket for comparison. Two different adhesives were used, a so-called no-mix and a paste/paste adhesive. The shear bond strength of the ceramic bracket was found to be superior for both adhesives.

Bond strength of thermally recycled metal brackets

American Journal of Orthodontics, 1983
Bracket recycling has emerged concurrently with the practice of direct bonding. This study was undertaken to determine the effect of recycling on the retention of mesh-backed stainless steel brackets. Mesh strand diameter was measured on forty new brackets.

Metal strength of direct bonding brackets

American Journal of Orthodontics and Dentofacial Orthopedics, 1998
Because the strength of direct bonding brackets is both important and difficult to measure, a related property, microhardness, has been investigated. Twelve popular U.S. brands of direct bonding brackets have been tested with a Vickers-Hanemann microhardness apparatus.

Biodegradation of orthodontic metallic brackets and associated implications for friction

American Journal of Orthodontics and Dentofacial Orthopedics, 2011
This study aimed to assess the effect of clinical exposure on the surface morphology, dimensions, and frictional behavior of metallic orthodontic brackets.Ninety-five brackets, of 3 commercial brands, were retrieved from patients who had finished orthodontic treatment. As-received brackets, matched by type and brand, were used for comparisons.

A posttreatment survey of direct bonding of metal brackets

American Journal of Orthodontics, 1978
Abstract A posttreatment evaluation of 180 orthodontically treated patients having 2,218 bonded brackets was made with a sealant and liquid-powder and paste-paste, chemically polymerized composite materials. All brackets were bonded by the author employing edgewise, Begg, and Begg Chun-Hoon brackets. By lightly tying 0.007 (0.178 mm.) inch ligatures
