In a loading device the mesio-distal deflection of mod restorations caused by different forces is measured reproducibly with inductive transducers. The accuracy of the measurements is about +/- 1 micron. Uncemented inlays of a soft gold casting alloy deflect 40 microns under load and 25 microns permanently; for an extra hard gold casting alloy the maximum values amount to 30 and 5 microns, respectively, and for a silver palladium alloy to 15 and 2 microns, respectively. Restorations of a non-gamma-2 amalgam reveal deflections within the range of accuracy near 2 microns.
在一种加载装置中，使用感应式传感器可重复测量不同力引起的MOD修复体近远中向变形。测量精度约为±1微米。软质铸造金合金的未粘结嵌体在加载时变形40微米，永久变形25微米；对于超硬质铸造金合金，最大值分别为30微米和5微米，对于银钯合金，分别为15微米和2微米。非γ-2型汞合金修复体的变形在精度范围内接近2微米。
