The plat castable ceramic crown was made with investment material prepared in our college with our own casting technique by a Chinese-made casting machine. The accuracy and fitness of the crown were studied and appraised. Results show that the margin of fitness is 46 microns and that the cement film thickness of the dies in the spacer material group is 65.13 microns. Hence the results are satisfactory. The Plat castable ceramic crown might be used in clinical dentistry.
采用本校自行研制的包埋材料，利用国产铸造机，通过自身的铸造技术制作出PLAT可铸型陶瓷全冠，并对其精度和适合性进行研究和评价。结果显示，适合性边缘为46微米，间隙材料组代型的粘固剂膜厚度为65.13微米。因此结果令人满意。PLAT可铸型陶瓷全冠可应用于临床口腔医学。
