Abstract
An improved dental composition having shortened hardening time and after hardening increased compressive strength and abrasion resistance, including a radical-inducing compound and a polymerizable acrylic or methacrylic acid ester or diester compound with at least 20 percent by weight of the polymerizable compound being the diacrylic or dimethacrylic acid ester of bishydroxymethyltricyclo [5.2.1.0.sup.2,6 ]-decane. Other monofunctional or difunctional acrylic or methacrylic acid esters as well as fillers, pigments and stabilizers can be included.
Claims12
A dental composition, especially for tooth fillings and dentures, including at least two components, one component comprising a polymerizable diacrylic acid ester selected from the group consisting of the diacrylic acid ester or dimethacrylic acid ester of bishydroxymethylthricyclo [5.2.1.0.sup.2,6 ]-decane and mixtures thereof, the other component comprising a radical-forming substance.
In a method for forming dental fillings and prosthetic dental applicances in which a polymerizable diacrylic or dimethacrylic acid ester is polymerized to form a hardened product, the improvement wherein at least 20 percent of said polymerizable ester is the ester of bishydroxymethyltricyclo [5.2.1.0.sup.2,6 ]-decane.
An improved dental composition having shortened hardening time and after hardening increased compressive strength and abrasion resistance comprising a polymerizable acrylic or methacrylic acid ester or diester and a radical-forming compound, at least 20 percent of the polymerizable ester being the diacrylic or dimethacrylic acid ester of bishydroxymethyltricyclo [5.2.1.0.sup.2,6 ]-decane.
