| 内容記述 | Precision casting is essential in current dental techniques. It is difficult to eliminate the air bubbles admixed in the investing by polishing after casting. Two practical methods are used to eliminate the air bubbles. These are the vaccuum investing method and the pressure investing method. We have experimented with the latter method, testing the effect of applying pressure right after investing, in an attempt reduce the air bubbles. We used, as investments, Shofu-crystbalite investment, GC ceravest and Whip-mix cerami gold, and we tested vacuum mixing at the standard viscosity for each. In the case of crystbalite, however, we also added hand mixing, changing the length of pressure time (0, 5, 10, 15, 20 minutes) as well as the amount of pressure (0, 2, 4, 6 kg/cm^2). Pressure was applied to the crystbalite samples once they had been left undisturbed after investing. For phosphate bonding investments, pressure was applied to samples that were heated after investing as well as to samples that were left undisturbed. Surface roughness was tested for five samples of each kind by replacing the plastic pattern with metal, and comparing the results with normal values. In conclusion, the above tests showed, in the case of crystbalite, that best results were obtained under 4 kg/cm^2 pressure applied for 15 minutes and that no prominent diffrence was found between hand mixing and vacuum mixing. With ceravest, pressure eliminated the compressive strength and thus adversely affected the surface roughness, indicating that pressure is not suitable for this material. With cerami gold the best result was obtained under 6kg/cm^2 of pressure applied for more than 10 minutes. | |||||||
