The effect of three different powder/liquid ratios of one zinc phosphate cement on the early retention of a standard crown on metal and tooth dies was investigated. Two different seating pressures were evaluated. The results indicate that the effect of variation in the powder/liquid was not significant. The part played by the seating force was significant, the higher seating force resulting in a greater force being required for displacement after 1 h. Greater forces of removal were required when tooth dies were used.
研究了一种磷酸锌水门汀三种不同粉液比对标准冠在金属和牙齿代型上早期固位的影响。评估了两种不同的就位压力。结果表明，粉液比变化的影响不显著。就位力所起的作用显著，较高的就位力导致1小时后位移所需的力更大。使用牙齿代型时需要更大的去除力。
