由于银汞合金张力不足,使其应用范围大为受限。对于大的(牙合)面缺损,为使之能耐受咀嚼力量,常不得不采用黄金或其他复杂的方法进行修复。在牙本质中插入针以增强银汞充填体,这种方法的问世,显著地减少了对黄金或其他复杂修复体的需要。1897年Arthur首先介绍在牙本质中增加螺钉使修复体获得固位的方法,但直到1958年Markley推广之后,才为大家所接受。由于银汞合金象混凝土一样脆弱,易崩溃,这种使用金
Due to lack of tension of silver-mercury alloy, its application is greatly limited. For large (occlusal) surface defects, in order to make it able to withstand the power of chewing, often have to use gold or other complex methods to repair. The introduction of needles in the dentin to enhance amalgam fillings has resulted in a significant reduction in the need for gold or other complex prostheses. Arthur first introduced in 1897 the method of adding screws to dentures to restore the prosthesis, but it was not accepted until after Markley promoted it in 1958. As amalgam as concrete as fragile, easy to collapse, this use of gold
