齿科铸造已有近百年的历史,脱模铸造是最早用于齿科铸造的方法。60年代以来。由于磷酸盐高温包埋料的研制成功,带模铸造工艺被广泛采用,支架整体铸造得以实现。方便了技工操作,亦提高了精度。更扩大了铸造支架的适应范围;而脱模铸造法,因为受蜡的物理性能限制,操作困难,则渐渐遭到冷落。近年来,我们在开展高温铸造的工作中,往往缺乏现成的磷酸盐包埋料,要配制,其主要成分方石英又不 Dental casting has been nearly a hundred years of history, release casting is the first method used for dental casting. Since the 60s. Due to the successful development of phosphate high temperature embedding material, die casting process is widely used, the overall stent can be achieved. Facilitate the mechanic operation, but also improve the accuracy. But also expand the scope of the casting stent; and stripping casting method, because of the physical limitations of wax, difficult to operate, then gradually been left out. In recent years, we carry out the work of high temperature casting, often lack of ready-made phosphate embedded material, to be prepared, the main component of cristobal and not
