Debonding of ceramic brackets by Er:YAG laser
PURPOSE The objective of the present study is to evaluate the effects of Er:YAG laser debonding of ceramic brackets on the bond strength and the amount of adhesive resin remnant. MATERIALS AND METHODS Twenty human mandibular incisors were randomly divided into two groups of 10 and polycrystalline ceramic brackets (Transcend series 6000, 3M Unitek, Monrovia, CA, USA) were bonded on enamel surf...
متن کاملImmediate and Delayed Effects of Diode Laser on Debonding of Ceramic Brackets: An in vitro Study.
AIM The aim of the study is to evaluate the immediate and delayed effects of diode laser on debonding of ceramic brackets. MATERIALS AND METHODS A total of 60 human extracted premolar teeth were randomly assigned to three different treatment groups. All teeth were bonded with adhesive precoated (APC) ceramic brackets (3M Unitek). A total of 20 teeth were debonded without lasing (group 1), 20 ...
متن کاملEffects of Diode Laser Debonding of Ceramic Brackets on Enamel Surface and Pulpal Temperature.
AIM Debonding of ceramic brackets due to their high bond strength and low fracture toughness is one of the most challenging complications of orthodontic clinicians. Application of lasers might be effective in the debonding of ceramic brackets as they reduce bond strength of resins and, therefore, can eliminate the risk of enamel damage. However, the thermal effects of laser radiation on dental ...
متن کاملPulpal Thermal Changes following Er-YAG Laser Debonding of Ceramic Brackets
Lasers are effective in debonding ceramic brackets. Unfortunately, while reducing the adhesive bond strength, lasers are also reported to increase pulpal temperature. The aim of this study was to evaluate the shear bond strengths and temperature increase levels after debonding ceramic brackets using an Er-YAG laser with or without water-cooling. Sixty polycrystalline upper premolar ceramic brac...
متن کاملThe use of easily debondable orthodontic adhesives with ceramic brackets.
We experimentally produced an easily debondable orthodontic adhesive (EDA) containing heat-expandable microcapsules. The purpose of this in vitro study was to evaluate the best debondable condition when EDA was used for ceramic brackets. Shear bond strengths were measured before and after heating and were compared statistically. Temperatures of the bracket base and pulp wall were also examined ...
