    摘要: A method of making a dental impression which comprises applying to the structure of which an impression is to be made a special prepolymer. The prepolymer is composed of units of at least one macrodiol, at least one aliphatic polyisocyanate, and an unsaturated monoalcohol as chain terminator, wherein the average functionality of the prepolymer based on the unsaturated groups is >2.

    摘要: In a dental composite containing a polymerizable (meth)acrylic compound, photoinitiator, accelerator, inorganic filler and conventional auxiliaries, the improvement wherein the composite by weight comprises about(a) 10-50% of at least one monomer which contains at least 2 polymerizable (meth)acrylic acid groups,(b) 5-80% of a glass or a glass ceramic which has an average particle size of between about 0.1 and 10 .mu.m and has been post-treated with .gamma.-methacryloxypropyltrimethoxysilane up to a carbon content of between about 0.5 and 2.5% by weight,(c) 2-10% of a surface-treated microfiller and(d) 0.1-5% of a photoactivator consisting of a mixture of camphorquinone and p-dialkylaminobenzenesulphonamide. The composition has a long pot life and good surface color when cured.
