Rapid mixing of zinc phosphate cement for fixed prosthodontic procedures.
This study was done to determine the efficacy of rapidly mixing zinc phosphate cement in conjunction with fixed prosthodontic procedures. Properties measured included rate of pH change and temperature increase, film thickness, and setting time. The rapid mix technique in conjunction with the frozen glass slab resulted in a faster elevation of the pH but slightly greater temperature rise and film thickness. As was expected, the rapid mixing procedure resulted in an increased working time but decreased setting. On the basis of this study, it appears that the rapid mixing technique in conjunction with a frozen glass slab is an acceptable technique for preparing zinc phosphate cement for fixed prosthodontic procedures.
