口腔科印模胶简称打样膏,具有热软冷硬的可逆特点,常用于制作个别托盘或印取辅助印模.其缺点是经反复使用后容易老化,直接影响模型的精确度,如将其抛弃将会造成浪费.为克服印模胶的老化缺点,传统的做法是在印模胶内加入松香或新的印模胶.近年来我科采用在旧的印模胶内加入烛蜡亦取得满意效果.其方法是将即将老化的印模胶(指印模胶在常规的水温中不易软化,可塑性差)放入盛有70℃以上水温的容器内加热软化,待印模胶具有流动性时随即逐次加入适量的家用照明烛蜡反复揉和均匀.加入的量以达 Stomatological imprinted plastic is called as proofing paste, which has the characteristics of reversible hot and cold, which is often used in the production of individual trays or auxiliary printed impressions. The disadvantage is that aging after repeated use directly affects the accuracy of the model, Abandonment will result in waste. In order to overcome the shortcomings of the aging of stamping glue, the traditional approach is to add rosin or new stamping gum in the stamping gum. In recent years, our department has also adopted candle waxing in the old stamping gum Satisfactory results: The method is to be aging plastic stamping (fingerprinting plastic in the conventional water temperature is not easy to soften, poor plasticity) into the container filled with water temperature above 70 ℃ to soften the heat until the stamping plastic fluid Then add the appropriate amount of home lighting wax candle repeated kneading and uniform
