摘　　要：采用Ｋ２Ｏ，Ｎａ２Ｏ－ＭｇＯ－Ａｌ２Ｏ３－ＳｉＯ２－Ｆ微晶玻璃系统进行配方筛选，确立了口腔修复用ＷＣＭＭ可切削微晶玻璃的组成范围。并通过差示热、Ｘ射线衍射、扫描电镜（ＳＥＭ）等分析手段对材料的晶化特性、晶体结构进行了测定。其理化性能表明，ＷＣＭＭ可切削微晶玻璃可为ＣＡＤ－ＣＡＭ修复技术提供冠、贴面、嵌体制作材料。The aim of this work was to investigate machinable glass ceramics used as oral restoration material in K 2O MgO AL 2O 3 SiO 2 F glass system. By using of DTA, XRD and SEM investigation, the crystalline structure and chracteristics were tested. The chemical composition of WCMM machinable glass ceramics was defined by the following general formula: (K,Na)Mg3-3x Al 2x (Al Si 3) O 10 F 2 (0.5≤x<0.7). The experimental results show that WCMM is an excellent oral restoration materials in the fabrication of crowns, inlayers and veneers.
