In this case report, an accepted technique was used to fabricate a crown to fit an existing removable partial denture in which castable glass was used instead of gold. The use of castable glass allowed the crown to be cast directly from a wax-acrylic pattern and eliminated the need for templates to produce accurate facial contours in porcelain. Although castable glass has limitations and cannot be used in all such situations, the material can be used in selected cases where esthetics is important.
在本病例报告中，采用了一种公认的技术来制作一个适合现有可摘局部义齿的冠，其中使用可铸玻璃代替了金。可铸玻璃的使用使冠能够直接从蜡 - 丙烯酸树脂模型铸造而成，并且无需模板即可在瓷体中产生精确的面部轮廓。尽管可铸玻璃有局限性，不能用于所有此类情况，但在美学很重要的特定病例中可以使用这种材料。
