卡扣结构中许多必要的术语，如强度和保持力，都可以用数字表示。然而，通过适当选择定义，它们也可以是相加的，这样计算就可以简化为最简单的加法和减法过程。例如，搭扣的强度可以用三个部分的总和来评估——搭扣、材料和齿。卡扣的质量或价值衡量的是卡扣的性能，就像强度一样，是卡扣、材料和齿这三个质量组成部分的总和。该方法不仅提供了一种评估整体性能的方法，而且更特别的是，评估卡扣设计中形状和锥度的相对优点以及不同材料对卡扣工作的适用性。材料的Qm值可以从公开的数据中计算出来，并为未来的搭扣材料研究提供了一个框架。
Many terms necessary in clasp construction such as strength and retention can be expressed numerically. However, by suitable choice of definitions, they can also be made additive so that calculations are reduced to the simplest procedures of addition and subtraction. The strength of the clasp, for example, can be assessed as the sum of contributions from three components—the clasp, the material, and the tooth. The quality or value ofQof the clasp measures clasp performance and, like strength, is the sum of three quality components, from the clasp, the material, and the tooth.This method gives a means of assessing not merely the over-all performance but, more especially, the relative merits of shape and tapering in clasp design and the suitability of different materials for clasp work.TheQvalue of the material,Qm, can be calculated from published data and offers a framework for future research on clasp materials.
