    摘要: A curable and radiopaque substance, a material that can be produced from same via polymerisation, a method for producing the curable substance and the cured material, and the use of the curable substance or the cured material are disclosed. The curable substance or the cured material can be used in, inter alia, orthopaedics as so-called bone cement, in particular as a tooth filling material, dental cement, dental lining material, flowable composite material (flow material) etc., as well as in diagnostic radiology. The invention also relates to the use of the curable substance generally as a construction material in an additive manufacturing process using a digital data model.

    摘要: An object of the present invention is to provide a dental composition that exhibits small polymerization shrinkage stress, and provides excellent mechanical strength. The present invention relates to a dental composition comprising a compound (A), a monomer (B) having a solubility of 50 g/L or more in acetone at 25° C., and a polymerization initiator (C),
    wherein the compound (A) has a weight-average molecular weight of 1,000 to 80,000, and includes a Tg of less than 40° C., in addition to having a solubility of less than 50 g/L in acetone at 25° C. Preferably, the compound (A) comprises a compound having a polymerizable group.
