As additional application of occlusal surface resin in antificial resin tooth of denture during use, splint and temporary restoration. All require materials which can be easily and properly applied. The authors tentatively made several preparatiorts of visible light-curing tooth crown resin using cyclophosphazene monomer on an experimental b;tsis, because this monomer has neither odor nor taste. We determined basic characteristics of these preparations and their adhesive strength to a resin teeth, and the results were compared with those seen in 2 commercially-available materials. As a result, the following results were obtained. 1. As for mechanical characteristics, the preparation containing an organic composition filter and that containing a large amount of U-2 TH as a como:nomer showed large bending strength, and the preparation containing a large amount of cyclopltosphazene monomer and that containing an organic composition filler had great compressive strength as well as large Rockwell har dness. 2. Preparations of these 3 types all showed a relatively large contact angle. 3. Satisfactory wear resistance was o bserved in preparations with large compression strength and hardness. The preparation containing an organic composition filter disclosed especially good results. 4. Our preparatiotas all demonstrated smaller impact resistance than the commerciallyavailable material B. 5. The preparation containing an organic composition filler showed the greatest adhesive strength, and the other 2 preparations showed the same as or even greater adhesie strength than the 2 commercially-available materials.
