印模胶为现行印模材料之一,并为多数口腔科工作者常采用,它主要优点是使用方便,缺点是准确性差。印模胶时间用久后,或经常用较高温度(80℃以上)水浸泡,使印模胶所含某些物质变性,导热能力变得很低,流动性也很差。具体表现为烫不软、硬固快、使用很不方便,弃之甚为可惜。为勤俭节约,我们试图利用某种物质的加入,来恢复它原来性能。经过数种试验,最后确定以羊毛脂为最好,现将配制方法介绍如下,供同志们参考。 Stamping gum is one of the current impression materials and is often used by most dentists. Its main advantage is easy to use, but its disadvantage is its poor accuracy. Stamping gel time with a long time, or often with a higher temperature (80 ℃ above) water so that the stamping gel contains some material denaturation, thermal conductivity becomes very low, poor liquidity. Specific performance is not hot, hard fast, very inconvenient to use, it is a pity to abandon. For thrifty, we try to use a substance to join, to restore its original performance. After several tests, the final determination of lanolin as the best, now the preparation methods are introduced below, for the comrades for reference.
