义齿基托折断是口腔修复中仍未解决的问题,尤其是上颌总义齿的纵折.为使基托结构较薄,又有足够的强度来承受强大的咀嚼力,临床上除了根据力学特性来指导临床设计工作以外,大多采用机械方法来提高义齿基托材料的强度,如局部埋入不锈钢丝、不锈钢管、尼龙丝网等物理措施,但效果不全尽人意.作者根据有机高分子复合材料的基本原理,研制出特殊形态的DMC-1铜基合金纤维,经偶联剂KH550处理后,按一定的重量比混入常规的基托材料中形成复合材料,能显著提高材料的弯曲强度和拉伸强度,取得较满意的效果.
Broken denture base is still unresolved problems in oral repair, especially the maxillary denture longitudinal fold. In order to make the base structure thinner, but also enough strength to withstand the strong chewing force, clinical clinical work in addition to the mechanical properties to guide the outside, the majority of mechanical methods to improve the strength of the denture base material, such as the local buried Stainless steel wire, stainless steel pipe, nylon mesh and other physical measures, but the effect is unsatisfactory. According to the basic principles of organic polymer composites, a special form of DMC-1 copper-based alloy fibers was developed. After being treated by coupling agent KH550, the composites were compounded into conventional base materials by a certain weight ratio, which could be significant Improve the bending strength and tensile strength of the material, to obtain more satisfactory results.
