摘要：
The present application relates to a dental curable composition that can be suitably used as a dental material that can substitute part or all of a natural tooth, in particular, a resin material for dental cutting and machining in the field of dental care. An object of the present application is to provide a dental curable composition in which, when a block shape usable as a resin material for dental cutting and machining is produced while mechanical properties such as hardness, bending strength and compressive strength as well as aesthetic property required for a crown prosthetic appliance are maintained, the dental curable composition can be molded and processed with pressure and heating while strain generated in the block is reduced and no cracks and chipping occur. There is provided a dental curable composition including (a) a polymerizable monomer and (b) a filler in a weight ratio of 10:90 to 70:30, and including 0.01 to 10 parts by weight of (c) a polymerization initiator and 0.001 to 1 part by weight of (d) a chain transfer agent being a terpenoid compound based on 100 parts by weight of the polymerizable monomer (a).
摘要（中）：
本申请涉及一种牙科用固化性组合物，其可以适当地用作可以代替天然牙齿的一部分或全部的牙科材料，特别是用于牙科护理领域的牙科切割和机械加工用树脂材料。 本申请的目的在于提供一种牙科用固化性组合物，其中，当可以用作用于牙科切削和机械加工的树脂材料的块形状时，产生硬度，弯曲强度和抗压强度等机械性能以及所需的美观性 为了保持冠状修复器具，可以通过加压和加热来模制和加工牙科用固化性组合物，同时减少在块中产生的应变，并且不会发生裂纹和碎裂。 提供了一种牙科用固化性组合物，其包含（a）可聚合单体和（b）重量比为10:90至70:30的填料，并且包含0.01至10重量份的（c）聚合引发剂和0.001 至（d）基于100重量份的可聚合单体（a）的链转移剂为萜类化合物1重量份。
