title: [Strength and elasticity of metals].
abstract: The bending test can be used to ascertain the suitability of various metals for use in dental prostheses, particularly as material for retaining elements. The effects of prior stress (i.e., bending) or the dependence of the strength characteristics on the production can be seen particularly following stress produced by permanent swelling. A comparison of the various test results showed that the value of the technical limits of elasticity (0.01%) alone should be used for the theoretical computations for clips used as retaining elements. Statements concerning the suitability of a particular metal under endurance stress can only be made in this way. The homogeneity of cast parts should be established by determining the raw density.
