摘　　要：本文通过SEM以及临床疗效观察综合评价了几种后牙充填材料的边缘密合性。结果发现:89—1后牙充填材料边缘密合最好;GC—Ⅰ型玻璃离子作后牙充填应慎用。Margin sealing property for some kinds of posterior teeth filling materials were studied by using SEM observation and clinical treatment effects. The results showed that 89-1 posterior teeth filling material had the best margin sealing property among the tested materials, GC-Ⅰ type glass ionomer should be care for using as a posterior teeth filling material.
