Thermal image analysis of electrothermal debonding of ceramic brackets: an in vitro study.
This study used modern thermal imaging techniques to investigate the temperature rise induced at the pulpal well during thermal debonding of ceramic brackets. Ceramic brackets were debonded from vertically sectioned premolar teeth using an electrothermal debonding unit. Ten teeth were debonded at the end of a single 3-second heating cycle. For a further group of 10 teeth, the bracket and heatin...
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 کاملDebonding 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 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...
