ABSTRACT:
A homogeneous porcelain block is used instead of using porcelain powder in a porcelain press technique to make dental prosthesis. Porcelain block is placed directly onto a mold, and softened by heating. Then the upper and the lower flasks of the mold assembly are closed so as to press the porcelain block. The process prevents adverse effects from steam and gases during the procedure. Therefore the porcelain block eliminates discoloration, bubbles, uneven baking and weakness in the porcelain block. In addition, considerable time and labor may be saved.
