Effect of aging type and aged unit on the repair strength of resin composite to feldspathic porcelain in testing microtensile bond strength

Abstract

(2016). Effect of aging type and aged unit on the repair strength of resin composite to feldspathic porcelain in testing microtensile bond strength. Journal of Adhesion Science and Technology, 30(4) Weibull modulus and characteristic strength was the highest in BTC (m=4.2; σ o: 34.4) among all other groups (m=3-3.9; σ o: 14.6-28.5). Adhesive failures were common and cohesive failures occurred in less than 5% in all groups. Aging protocol was detrimental on durability of repair strength of resin composite to feldspathic porcelain. Exposing the sticks to either thermocycling or water storage aging should be considered in in-vitro studies.

“…Stress is concentrated in certain regions of the samples by creating uneven stress distribution. In contrast, μTBS is carried out with samples of smaller sizes and provides a more homogenous and regular distribution of stress (Aboushelib, Kleverlaan, & Feilzer, 2006;Pashley et al, 1999 thermal changes on materials and bond strengths (Corazza, de Carvalho, Souza, Bottino, & Ozcan, 2016).…”

“…Application of thermal‐cycling to bar‐shaped specimens instead of blocks reduces μTBS. This procedure is more adequate for obtaining effects of thermal changes on materials and bond strengths (Corazza, de Carvalho, Souza, Bottino, & Ozcan, 2016).…”
