摘　　要：利用研制的连续波ＣＯ２激光器，对Ｂｉｓ－ＧＭＡ树指为基质，瓷粉为填料的复合树脂，进行激光辐照固化的实验研究、优选出最佳固化条件，并测试了复合树脂的压缩强度及表面硬度。结果表明：激光固化的复合树脂与其它方法固化的复合树指相比，其压缩强度较高，而表面硬度大致相当。激光固化方法，具有操作简便，无需添加促进剂，材料颜色稳定等特点，是一种较为理想的牙科复合树脂固化方法。Abstract A kine of composite, which contained Bis-GMA as matrix resin and porcelain powder as filler,was cured by a serial wave laser unit. The compressive strength and the surface hardness of the composite resin were also determined. The result showed that laser-curing composite resin was characterized by easy-operating, high mechanical Property. no accelerant and good color stability.
