本文通过扫描电镜和临床观察，对玻璃离子粘固剂牙体缺损充填术后打磨方法进行了研究。扫描电镜观察组以８０颗离体牙（牙颈部无缺损的前牙）为实验对象。实验组与对照组各４０颗。实验组打磨器为金刚砂和白头打磨器。对照组为传统绿色砂石打磨器。结果，边缘破折率经统计学处理Ｐ＜０．０１。对８０例前牙牙颈部缺损的患者采用玻璃离子粘固剂充填，４０例为实验组，４０例为对照组，经统计学处理Ｐ＜０．０５。
In this paper, scanning electron microscopy and clinical observation of glass ionomer cement dental implants postoperative grinding method was studied. Scanning electron microscopy observation group with 80 isolated teeth (tooth and neck defect-free anterior teeth) as the experimental object. Experimental group and control group each 40. Experimental group sander for emery and white head sander. The control group is a traditional green sand grinder. As a result, the edge rupture rate was statistically processed P <0.01. Eighty cases of anterior cervical and cervical deformity were filled with glass ionomer cement, 40 cases were experimental group and 40 cases as control group, which were statistically analyzed (P <0.05).
