Abstract
To provide a dental prosthetic material having processing characteristics and operating characteristics, which are not recognized in a conventional dental material. A biorestorative material which is a rubber elastic material having a shear modulus of 1.0-9.99 E+4 Pa to 1.0-9.99 E+9 Pa and a rubber hardness of 1 to 90, wherein a Knoop hardness can be 10 or more after polymerization.
Claims21
A biorestorative material which is a rubbery elastic material and has a shear modulus of 1.0.times.10.sup.4 Pa to 9.99.times.10.sup.9 Pa at 23.degree. C. and a rubber hardness of 1 to 92. with a Knoop hardness of 10 or more after polymerization, comprising 14.5 to 62.5% by weight of a polymer, 10.0 to 37.5% by weight of a polymerizable monomer, 10.0 to 60.0% by weight of a silane-treated silica-dispersed uniformly iii urethane (meth)acrylate and a polymerization initiator.
