抄録

A new method for producing porcelain teeth by pouring muddy porcelain mixed with powder and water in a silicone impression mold, and then pressing and freezing it was developed and reported.<BR>This method has many advantages in comparison to the conventional pile method. This study was conducted to find countermeasures to compensate for the shrinkage of porcelain baked by this method. The right cylinder specimen (10 mm in diameter and 10 mm in height) with a conical concavity (8 mm in diameter and 1.3 mm in depth) on the top was used to examine the dimensional change between the metal model and ten porcelain specimens by a universal material testing machine.<BR>The results were as follows:<BR>In the first and second times using this method, the reproductive coefficient of porcelain was about 84% and 94% of the original model, respectively. The dimensional difference between the baked porcelain and the metal model decreased by using this method two times. It was suggested that the porcelain teeth shaped and baked by using the freezing method could be similar to the original models.
