在口腔科铸造操作中,需用多种不同形状粗细的蜡条。由于市面上很少出售,有些地方往往用手制作,很费时,长期以来我们采用此种器械压蜡条效果很好。特介绍如下: 组成:1.上半部:用低碳钢在车床上加工(以下同)。2.下半部:在下半部底部稍上方钻一孔,要求大于外圈上任何形状小孔。3.外圈:在外圈底部,即与下半部底孔水平相应部位,分別绕圈作一排不同形 In dental casting operations, the need to use a variety of different shapes and sizes of wax. As the market seldom sold, some places are often hand-made, it is time-consuming, for a long time we use this device pressure wax effect is very good. Special introduction is as follows: Composition: 1. Upper part: machining with low carbon steel in the lathe (the same below). 2. Bottom half: Drill a hole slightly above the bottom half of the bottom half, requiring more holes than any other shape on the outer ring. 3. Outer ring: at the bottom of the outer ring, that is, with the corresponding part of the lower half of the bottom hole, respectively, around the circle for a row of different shapes
