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.

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.

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.
