Title (EN) PROVISIONAL CROWN-AND-BRIDGE RESIN
(FR) RESINE POUR COURONNE ET BRIDGE
Abstract: front page image
(EN)A provisional crown-and-bridge resin comprising a liquid resin component and a powder component. The liquid resin component contains tetrahydrofurfuryl methacrylate as a major ingredient and is free from methyl methacrylate. It also contains an anti-oxidant and an accelerator. The powder component contains poly (ethyl methacrylate) as a major ingredient and a curing agent for the resin component. The powder is mixed with the resin shortly before application at a ratio of about two to about five parts of powder to one part of liquid resin by weight, to give a suitably flowing mixture. The resin component may also contain ethyl methacrylate as a major ingredient and may contain ethoxylated bisphenol A dimethacrylate as a major ingredient. The powder may include a substantial proportion of amorphous silica and preferably incorporates a substantial amount of X-ray opaque barium glass.
