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 کاملDoes the CO2 laser reduce bond strength in different types of ceramic brackets?
OBJECTIVE: The aim of this study was to assess in vitro the influence of the CO2 laser and of the type of ceramic bracket on the shear bond strength (SBS) to enamel. METHODS: A total of 60 enamel test surfaces were obtained from bovine incisors and randomly assigned to two groups, according to the ceramic bracket used: Allure (A); Transcend (T). Each group was divided into 2 subgroups (n = 1...
متن کاملThermal 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 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 ...
