在口腔镶装修复工作中,制取完整精确的石膏模型,既是镶装医师的基本操作技术,又是义齿成败的关键之一。为防止灌注石膏模型时出现气泡,我们制做了一台灌注模型震荡器。1.器材:(1)电动机(旧电扇电动机)。(2)U 形钢丝架(12号钢丝弯制而成)。(3)弹性钢条(钢锯条制作)。(4)基木(小方木4×3×1.5cm)。(5)脚踏开关。2.制作方法:在电动机尾部及中部的上端按2个固定螺旋,在弹性钢条的相应部位打孔并用螺旋固定在电动机上,使游离端能上下弹动。再把制好的基木用木螺钉固定在弹性钢条游离端上方,然后在基木下
In the oral inlaid repair work, to obtain a complete and accurate gypsum model is not only the basic operation of the dentist physician, but also one of the keys to the success or failure of the denture. To prevent air bubbles from pouring into the gypsum model, we made a perfusion model oscillator. 1. Equipment: (1) motor (old fan motor). (2) U-shaped wire rack (12 wire bent from the system). (3) flexible steel bar (hacksaw production). (4) Base wood (small square wood 4 × 3 × 1.5cm). (5) Foot switch. 2 production methods: the tail in the motor and the upper end of the two fixed spiral, the corresponding part of the flexible steel perforated and fixed with a screw on the motor, so that the free end can bounce up and down. Then make a good base wood with wood screws fixed in the free end of the elastic steel above, and then under the wood
