铝镁中熔铸金,我科自1965年开始应用于临床,经过十几年的随访结果,认为铝镁中熔铸金适用于单个固定修复及前牙3/4冠桥,可以部分代替贵金属。原来由于采用非真空离心浇铸,铸件有小针孔和疏松等缺陷,影响了表面质量和强度以及抗腐性能。为了提高铸件质量和成品率,我科和上海市有色金属研究所, Magnesium alloy casting, our department has been applied to clinical since 1965, after more than 10 years of follow-up results, that the cast aluminum alloy suitable for a single fixed repair and anterior teeth 3/4 crown bridge, you can partially replace the precious metal. The original due to the use of non-vacuum centrifugal casting, casting a small pinhole and porosity and other defects, affecting the surface quality and strength and corrosion resistance. In order to improve the casting quality and yield, our branch and Shanghai Nonferrous Metal Research Institute,
