A machined brass crown, onto which a strain gauge had been attached, was filled with a silicone fluid and placed on various dies to simulate luting using zinc phosphate cement. Space between the crown and the die was varied, as was the seating force. As the load increased, crown deformation increased and time to seat decreased. Increasing the axial space decreased the time to seat but did not affect the strain recorded for a given load.
一个已安装应变片的加工黄铜牙冠，填充硅酮流体后放置在各种代型上，以模拟使用磷酸锌水门汀粘固。牙冠与代型之间的间隙以及就位力均有所变化。随着负荷增加，牙冠变形增大，就位时间缩短。增加轴向间隙可缩短就位时间，但不影响给定负荷下记录的应变。
