本文通过观察银锡铜钯球形合金和镓铟锡银球形合金在Ⅰ类牙体修复过程中的周期性变化，探讨了银锡铜钯球形合金和镓铟锡银球形合金的临床应用可能性。在所有测试的修复体中，表面纹理和边缘完整性在一年后已经恶化。因此，认为金属塑性充填材料不能克服口腔内的物理和化学应力，需进一步改进，才能替代高铜汞合金。
The possibility for the clinical application of an experimental restorative material, which is composed of an Ag-Sn-Cu-Pd spherical alloy and a Ga-In-Sn-Ag alloy, was examined by observing periodic changes during class I restoration. In all of the restorations tested, the surface texture and the marginal integrity had deteriorated after a period of one year. Therefore, it was concluded that this metallic plastic filling material couldn't overcome physical and chemical stresses in the mouth, as a result, some improvement is required before this material can be substituted for the high copper amalgam.
