Ltd., Solidex (SO) by Shofu Inc., Axis (AX) by GC Corp., and Estenia (ES) by Kuraray Co. Ltd. The thermal expansion coefficient, flexural strength, hardness, compressive strength, and elastic modulus of each type were examined for dentine and enamel colors. Furthermore, the fracture strength of jacket crowns produced from these types of hard resin examined. The results were as follows : 1. The thermal expansion coefficient decreased in order of AX, SO, CE, and ES. The coefficient of ES was especially small, approximating that of gold alloy. 2. ES had higher values for both flexural strength and hardness, as compared with the other three hard resins. Its flexural strength value was more than 2 times higher in dentine, and its hardness value was 2 to 7 times higher in enamel. 3. All four types of hard resin had compressive strength 2 to 5 times higher and elastic modulus I to 4 times higher than the values of general acrylic resins. 4. The fracture strength of jacket crowns made from ES was significantly higher than those made from CE and AX., 紀要類(bulletin), 622805 bytes},
