Abstract

The invention relates to a dental restorative material on the basis of at least one compound of Formula IA-[X-Q-(Y-CG)n]m   Formula I,wherein CG represents in each case independently an azide group N3 or an alkyne group selected from the group consisting of —CR1R2—C≡CH,with the proviso that the dental restorative material comprises at least one compound of Formula I comprising an azide group and at least one compound of Formula I comprising an alkyne group.The invention also relates to the use of the dental restorative materials according to the invention for preparing dental composites, preferably composite blanks, which are suitable in particular for mechanical processing by means of computer-aided processing techniques such as milling and grinding processes, and which are suitable above all for preparing dental restoration materials such as inlays, onlays, crowns, bridges or veneering materials.
