Assessment of Bond Strength between Metal Brackets and Non-Glazed Ceramic in Different Surface Treatment Methods
OBJECTIVE The aim of this study was to evaluate the bond strength between metal brackets and non-glazed ceramic with three different surface treatment methods. MATERIALS AND METHODS Forty-two non-glazed ceramic disks were assigned into three groups. Group I and II specimens were etched with 9.5% hydrofluoric acid. Subsequently in group I, silane and adhesive were applied and in group II, bond...
متن کاملMicro-shear bond strength and surface micromorphology of a feldspathic ceramic treated with different cleaning methods after hydrofluoric acid etching
OBJECTIVE The aim of this study was to evaluate the effect of feldspathic ceramic surface cleaning on micro-shear bond strength and ceramic surface morphology. MATERIAL AND METHODS Forty discs of feldspathic ceramic were prepared and etched with 10% hydrofluoric acid for 2 minutes. The discs were randomly distributed into five groups (n=8): C: no treatment, S: water spray + air drying for 1 m...

متن کاملEffect of etching time and light source on the bond strength of metallic brackets to ceramic.
This study evaluated the bond strength of brackets to ceramic testing different etching times and light sources for photo-activation of the bonding agent. Cylinders of feldspathic ceramic were etched with 10% hydrofluoric acid for 20 or 60 s. After application of silane on the ceramic surface, metallic brackets were bonded to the cylinders using Transbond XT (3M Unitek). The specimens for each ...
متن کاملEffect of the Etching Duration and Ultrasonic Cleaning on Microtensile Bond Strength Between Feldspathic Ceramic and Resin Cement
This study assessed the effect of different etching time of hydrofluoric acid and ultrasonic cleaning of the etched ceramic surface on the resin microtensile bond strength stability to a feldspathic ceramic. The research hypotheses investigated were: (1) different etching time does not affect the adhesion resistance; (2) ultrasonic cleaning improves the adhesion resistance. Forty-eight (48) blo...
