Abstract

Modern casting materials are becoming available in an increasing and bewildering variety. A series of tests has been devised to investigate the properties of these materials. They have been tested for strength, flexibility, lamination, fatigue life and radiolucency. Their properties have been compared with those of plaster of Paris in order that the role of the newer materials can be defined. It is suggested that the tests described might form the basis of a standard from which user trials could be designed to appraise the value of these materials in clinical practice.

摘要

现代铸造材料的种类日益繁多，令人眼花缭乱。已经设计了一系列测试来研究这些材料的性能。它们已经过强度、柔韧性、分层性、疲劳寿命和射线透过性测试。已将它们的性能与熟石膏的性能进行了比较，以便确定这些新材料的作用。建议所描述的测试可以形成一个标准的基础，据此可设计用户试验来评估这些材料在临床实践中的价值。
