Invisible orthodontics part 3: aesthetic orthodontic brackets

open access: yesDental Update, 2013
In this, the third part of the series, aesthetic orthodontic treatment will be considered. The previous two articles have looked at invisible orthodontics with Invisalign and lingual brackets. This article will discuss the properties and use of aesthetic brackets, along with examples of orthodontic treatment cases using the aesthetic brackets ...

Antibacterial Activity of Orthodontic Cement Containing Quaternary Ammonium Polyethylenimine Nanoparticles Adjacent to Orthodontic Brackets

open access: yesInternational Journal of Environmental Research and Public Health, 2018
Enamel demineralization is a common problem found in patients using orthodontic devices, such as orthodontic braces. It was found that Streptoccocus mutans growth increases adjacent to orthodontic devices, which may result in caries development ...

Endotoxin affinity for orthodontic brackets

American Journal of Orthodontics and Dentofacial Orthopedics, 1999
Endotoxin, cell envelope lipopolysaccharide produced by gram-negative bacteria can activate an immune response through a variety of pathways. In addition, it can stimulate bone resorption and reduce the periodontal tissue's healing capacity. Previous studies have documented the affinity of lipopolysaccharide for restorative materials.

Biodegradation of the orthodontic bracket system

American Journal of Orthodontics and Dentofacial Orthopedics, 1986
Corrosion of the orthodontic appliance may occur in vivo with time. Electrochemical breakdown of corrosion-resistant high nickel and titanium wire can also occur. The use of recycled brackets could possibly accelerate the corrosion process. New and recycled brackets were evaluated in vitro in an artificial saliva system.

Corrosion of orthodontic bracket bases

American Journal of Orthodontics, 1982
Attention has recently been focused on the development of black and green stains in association with directly bonded stainless steel brackets. Twelve clinical cases of staining were studied in this investigation. After intraoral photography of the stains, the brackets were removed for examination with the scanning electron microscope.

Bandless orthodontic bracket

The Journal of the American Dental Association, 1967
The bandless M bracket protects adhesives that attach orthodontic brackets directly to teeth. Without the M bracket, tested adhesives encountered moisture and integrity of bond was not maintained.

Direct bonding of orthodontic brackets

American Journal of Orthodontics, 1976
The direct adhesive bonding of orthodontic brackets to enamel was investigated. For a number of resin systems, all based on a bisphenol-GMA type of resin, commercially available or synthesized, the adhesive bonding to the enamel as well as to the bracket was studied. The maximum average bond strength to enamel was 121 Kg.

Torsional creep of polycarbonate orthodontic brackets

Dental Materials, 1997
Polycarbonate materials are known to exhibit creep. The purpose of this study was to investigate torsional creep of polycarbonate orthodontic brackets.Four polycarbonate, one metal, and one ceramic brackets were tested. An in vitro torque apparatus was constructed which applied 2000 g-mm of torque to the bracket slot via a cantilever beam perpendicular

Bond strength of rebonded orthodontic brackets

American Journal of Orthodontics and Dentofacial Orthopedics, 1996
A study was undertaken to determine the bond strength of brackets rebonded with a no-mix resin system or a paste-paste resin system. The efficacy of plastic conditioner and Enhance adhesion booster (Reliance Orthodontic Products, Inc., Itasca, Ill.) as an aid in rebonding was also evaluated.
