Simulated Intraoral Laser Microwelding of Orthodontic Appliances.
The heat produced at the dentinal pulpal wall opposite the irradiation site was measured during etching of dental enamel with an Nd:YAG laser in preparation for direct bonding of orthodontic applian...
The application of laser irradiation to etch dental enamel in preparation for direct bonding of orthodontic appliances has been studied. Forty extracted human teeth were divided into four groups of 10...
Laser-aided degradation of composite resin
Laser Nd: YAG Composite resin Dental enamel Orthodontic brackets
2009/1/9
The removal of residual composite resin after debonding orthodontic brackets often creates surface scratches, enamel loss, and enamel tearouts. If the Nd: YAG laser could selectively degrade the res...
Bond strengths of two ceramic brackets using argon laser, light, and chemically cured resin systems
Bond strength Ceramic brackets Resin Argon laser
2009/1/8
The present study compared tooth-bracket bond strengths using two types of ceramic brackets and three methods of polymerization: argon laser, conventional light, and chemical. Ninety extracted hum...
Polymerization with the Argon Laser：Curing Time and Shear Bond Strength
Argon laser Orthodontic bonding Shear bond strength
2008/12/29
The objective of this study was to determine the efficiency of an argon laser in polymerizing a light-cured orthodontic adhesive. Metal brackets were bonded to 185 premolars, divided into 5 differ...
Bond Strengths of Orthodontic Bracket After Acid-Etched, Er：YAG Laser-Irradiated and Combined Treatment on Enamel Surface
Orthodontic bonding YAG laser ablated Fracture mode
2008/12/19
Laser ablation has been proposed as an alternative method to acid etching; however, previous studies have obtained contrasting results. The purpose of this study was to compare the bond strengths af...
The Effect of Argon Laser Irradiation on Demineralization Resistance of Human Enamel Adjacent to Orthodontic Brackets: An In Vitro Study
Argon laser curing system White spot lesions Demineralization resistance Demineralization lesion depth
2008/12/19
Argon lasers, because of their significant timesavings over conventional curing lights, have been investigated for use in bonding orthodontic brackets. They are also being investigated for their abi...
