摘　　要：为了探讨ＧＩⅠ型粉浆涂塑铝瓷核冠玻璃料对铝瓷核冠雏型的渗透效果，为临床应用提供参考数据，我们通过实验测定１～６小时该种玻璃料渗透铝瓷核冠雏型的最小距离，得出了最小渗透距离与渗透时间之间的相互关系。结果表明，该二者间存在高度的直线相关关系，由此确定出临床医生应用该玻璃料渗透铝瓷核冠雏型时，单冠应至少渗透２５小时，桥架则应渗透５小时。本项研究结果对口腔修复临床工作有明确的指导意义。In order to explore the infiltration condition of GIⅠ slip casting aluminous ceramic core glass material to aluminous ceramic substratum and provide reference for clinical use, the linear change relationship between the minimal infiltration depth and infiltration time was determined by measuring the minimal depth of glass material infiltrated to aluminous ceramic substratum from one to six hours. The result showed: there is a high linear relationship between the minimal infiltration depth of GIⅠ infiltration glass and the infiltration time. For clinical use, the minimal infiltration time for GIⅠ slip casting aluminous ceramic core at least 2.5 hrs and 5 hrs for bridge framework.
