摘要

Dental compositions based on bifunctional acrylic esters exhibit rapid hardening, and the hardened mouldings have high compressive strength and low abrasion wear if the diacrylic ester is dimethacrylic or diacrylic ester or the corresponding mixed ester of bishydroxymethyltricyclo[5.2.1.02,6]decane. In addition to a free-radical former (for example redox system or photoinitiator), further acrylic esters, fillers, dyes and stabilisers may be present. The dental compositions can be employed as usual for the production, for example, of dental fillings or dental prostheses, such as crowns, and veneers of metal bridge frames.
