The fit of spark-eroded titanium and cast gold alloy copings was compared by assessment of retrieved cement film analogues. This technique was chosen for its simplicity, nondestructive nature, and for the information it provided on overall fit. The present study showed that the overall fit of titanium copings was comparable to that of gold copings. In marginal areas, the space between die and coping was found to be larger for spark-eroded than cast copings.
通过对回收的粘结剂薄膜类似物进行评估，比较了电火花加工钛和铸造金合金冠的适配性。选择该技术是因为其操作简单、无损性质以及它所提供的关于整体适配性的信息。本研究表明，钛冠的整体适配性与金冠相当。在边缘区域，发现电火花加工冠与铸造冠相比，代型与冠之间的间隙更大。
