The present study has shown that the accuracy of peridental gold alloy castings depends 1) on the type of casting machine used, 2) on the diameter of the casting sprue, and 3) on the strength properties of the investment material. The dependence between the accuracy and the three factors mentioned is based on erosion of the investment mold by the inflow of the liquid casting alloy. The vacuum casting technique proved to be a more gentle casting method than centrifugal and vacuum/pressure techniques.
本研究表明，口腔修复用金合金铸件的精度取决于：1）所用铸造机的类型；2）铸造浇道的直径；3）包埋材料的强度性能。上述精度与这三个因素之间的相关性是基于液态铸造合金流入导致包埋模具的侵蚀。事实证明，真空铸造技术比离心铸造和真空/压力铸造技术更为温和。
