在临床修复中,上半口义齿纵折、咬合垫和基托的断裂是经常发生的。多年来,临床上采用多种方法用于塑料基托内部的加强,以提高塑料的强度,或以金属基托取而代之。例:尼龙咬合垫、钢丝支架在基托中的合理分布等,均取得了好的效果。但有些还存在着铸造金属网状与塑胶分离剥脱,铸造基托与组织不密合、金属咬合垫易造成对 In clinical repair, the first half of the denture longitudinal fold, occlusal pad and the base of the fracture is often occurs. Over the years, a variety of methods have been used clinically to reinforce plastic substrates to increase the strength of the plastic or to replace it with a metal matrix. Example: Nylon bite pads, steel brackets in the base of a reasonable distribution, have achieved good results. However, there are still some casting metal mesh and plastic separation stripping, casting base and tissue is not close, the metal bite pad easily lead to
