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.
该发明涉及一种牙科修复材料,其基础是至少一种化合物Formula IA-[X-Q-(Y-CG)n]mFormula I,其中CG在每种情况下独立地表示一个偶氮基团N3或从一组中选择的炔基团,该组由—CR1R2—C≡CH组成,但是牙科修复材料至少包括一种包含偶氮基团的Formula I化合物和一种包含炔基团的Formula I化合物。该发明还涉及根据该发明的牙科修复材料用于制备牙科复合材料,优选为复合坯料,特别适用于通过计算机辅助加工技术(如铣削和磨削工艺)进行机械加工,并且特别适用于制备牙科修复材料,如嵌体、套环、冠、桥梁或贴面材料。
