目前临床上制作不锈钢固定桥取两次印模灌注两个石膏模型或用弹性印模村取一次印模灌注两个石膏模型，才能完成固定桥的固位体连拉体、桥体金属部分的焊接和桥体的制作。这样不但操作工序较繁杂，而且浪费了时间和大量的石膏。本文提出的改进的操作方法容易掌握，效果准确，缩 At present, the clinical production of stainless steel fixed bridge to take two impression perfusion two gypsum model or take an impression with the elastic mold village perfusion model two gypsum, in order to complete the fixed bridge fasteners even body, bridge metal parts Welding and bridge production. This not only complicated operation process, but also a waste of time and a lot of gypsum. The improved method of operation proposed in this paper is easy to grasp, accurate and compact
