Abstract: Polymerizable and hydrolysable oxetane silanes and in particular silicic acid condensates which can be prepared therefrom are described, which exhibit only a low volume shrinkage on polymerization and produce polymers with high mechanical strength and therefore can be used above all as dental material or constituent thereof.
Abstract translation: 描述了可聚合和可水解的氧杂环丁烷硅烷,特别是可由其制备的硅酸缩合物,其在聚合时仅显示低体积收缩率并且产生具有高机械强度的聚合物,因此可以首先用作牙科材料或其组分。

Abstract: A dental material is described which is characterized by a content of silicic acid condensates of norbornene or mercapto silanes, and which, after thiol-ene polymerisation with suitable reactants, shows only slight polymerisation shrinkage and produces polymerisates with high mechanical strength.

Abstract: X-ray opaque esters or amides of iodosubstituted benzoic acid according to formula I and polymers and dental materials produced therefrom. ##STR1## R.sup.1 =hydrogen or C.sub.1 to C.sub.3 alkyl, preferably H or CH.sub.3 ; R.sup.2 =straight-chain or branched C.sub.1 to C.sub.6 alkylene, oxyalkylene or arylene, preferably C.sub.2 to C.sub.4 alkylene and particularly preferably --CH.sub.2 --CH.sub.2 -- and --CH.sub.2 CH(--)CH.sub.2 --; X=O or NH, preferably O; R.sup.3 -R.sup.7 =at least 3 iodine substituents, preferably in R.sup.3, R.sup.4 and R.sup.6 or R.sup.3, R.sup.5 and R.sup.7 position, the other groups are hydrogen, C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy, --Cl, --Br, --OH, --NH.sub.2, --N(C.sub.1 to C.sub.6 alkyl).sub.2 or --NH--CO--(C.sub.1 to C.sub.6 alkyl), preferably R.sup.3, R.sup.4, and R.sup.6 are=I and R.sup.5 and R.sup.7 =H, or R.sup.3, R.sup.5 and R.sup.7 =I and R.sup.4 and R.sup.6 =--NH(COCH.sub.3); n=1, 2 or 3, preferably 1 or 2. The benzoic acid esters and amides according to the invention can be well polymerized radically or anionically, the polymers are well soluble in the usual dental monomers. Dental materials produced from the monomers or polymers are characterized in that the X-ray opaque component is bonded covalently into the polymeric matrix material and cannot therefore be washed out. Furthermore, excellent X-ray opacity can be achieved without using fillers.
