Bond strengths of five different ceramic brackets: an in vitro study

Abstract: The purpose of this investigation was to compare the bond strengths to enamel obtained in shear/peel and tensile/peel modes of testing using five different ceramic brackets and two different light-cured composites. The site of failure was also examined. Shear/peel bond strength was significantly affected by adhesive type, with Heliosit having higher mean bond strengths than Prismafil. Bond strength was significantly affected by bracket type; the highest mean bond strength in both tests being attained using Tra… Show more

“…Silanisation of the bracket because of the silane coupling agent is responsible for the chemical bond and it improves the bond strength. Because of a significant increase in the bond strength, the stress of debonding can also be shifted from the bracket -adhesive interface to the adhesiveenamel interface, which is likely to damage the enamel surface during the debonding procedure [13].…”

“…A busca por soluções estéticas aos aparelhos ortodônticos começou em 1965 com Newman, que introduziu acessórios plásticos tentando melhorar a aparência dos aparelhos ortodônticos 29 . A aplicação clínica destes braquetes, no entanto, foi limitada, em razão de problemas encontrados quanto à durabilidade 29 , estabilidade dimensional 28 , embebição por água e, como conseqüência, alteração de cor 15 . Tentando minimizar esses problemas apresentados, foram desenvolvidos, na década de 70, braquetes confeccionados em cerâmica 2,23 .…”

“…Tentando minimizar esses problemas apresentados, foram desenvolvidos, na década de 70, braquetes confeccionados em cerâmica 2,23 . No entanto, esses braquetes possuem limitações e dentre essas citam-se: alto custo, alta resistência do atrito à mecânica de deslizamento 14,17,20 e danos iatrogênicos ao esmalte durante a sua remoção 26,28 , por produzir forte união na interface compósito-braquete 21,22 . Além disso, a impossibilidade de sofrerem distorções 22 gera uma tensão demasiada na interface esmalte-compósito e, não raro, durante os procedimentos de descolagem pelas técnicas convencionais, ocorrem fraturas e danos importantes ao esmalte dentário 7,13,15 .…”
