为解决上颌总义齿纵析,我们在采用不锈纲片锤造局部基托的基础上,锤造了一些上颌全腭金属基托,经过实践与临床观察,基本达到预期的效果。翻制低溶合金阴阳模,具体操作与注意事项介绍于下:先将修整好的石膏模型置于水平位置上,用变色笔划出缓冲区、后堤区和金属基托边缘线。后在石膏模型上,用2层胶布粘在牙槽脊和上颌骨隆突(上颌硬区)上,前者解决金属基托与塑料结合,后者是达到缓冲目的。用油泥围住石膏模型,放上金属圈,去除圈内倒凹。熔化硬铅并注入圈内达一定厚度。为防
In order to solve the longitudinal analysis of the maxillary denture, we fabricated some maxillary full palate metal base on the basis of stainless steel plate hammer made of local base, through the practice and clinical observation, basically achieve the desired results. Low-alloy inverted yin and yang mold, the specific operation and precautions described in the following: First, a good plaster cast trims placed in a horizontal position, with a color pen out of the buffer zone, the embankment area and the edge of the metal base line. After the plaster model, with 2 layers of adhesive stuck in the alveolar ridge and maxillary protuberance (maxillary hard), the former to solve the metal base and plastic combination, which is to achieve the purpose of cushioning. Surrounded the gypsum model with the mud, puts the metal ring, removes the concave ring in the circle. Molten hard lead and injected into the circle up to a certain thickness. To prevent
