Objective To evaluate the different effect between the amalgam bonded with the glass ionomer cement and composite resin on restoring class ⅱ cavities without dove tail. 目的比较玻璃离子粘结银汞合金充填与复合树脂充填无鸠尾Ⅱ类洞的临床疗效。
An in vivo study on the adaption of glass ionomer cement based light cured composite resin restoration 玻璃离子体粘固粉作为光固化复合树脂基底材料的密合度研究
All-ceramic specimens were luted to the metal alloy by Zinc Phosphate cement, glass ionomer cement and composite resin. 将全瓷试件和背景试件分别用树脂粘接剂、玻璃离子粘固粉、磷酸锌粘固粉粘接,根据粘接材料的不同分为3组,每组4个。
Methods Application of glass ionomer cement, composite resin and sandwich technique were used to restore 398 wedge-shaped defect of the teeth. 方法:对398颗楔形缺损患牙分别用玻璃离子粘固粉、光固化复合树脂和玻璃离子粘固粉与光固化复合树脂联合修复(以下简称夹层技术)。
Results The successful rates were 94 07% in sandwich technique group 90 77% in glass ionomer cement group, and 81 97% in composite resin group. 结果:夹层技术组、玻璃离子粘固粉组和光固化复合树脂组总有效率分别为9407%、9077%和8197%。
Effect of glass ionomer cement sandwich technique in restoring wedge-shaped defect with light-cured composite resin 玻璃离子夹层对光固化复合树脂修复楔形缺损疗效的影响
In acid condition, the positive ionomer resin can get rid of the entire Al ion from the aluminum foil etching liquid. 酸性条件下,阳离子交换树脂能够将铝箔腐蚀液中的Al3+全部除去;
All of the three types of pit and fissure sealants showed lower microleakage, while the adaptation of glass ionomer material ( Fuji ⅸ GP) was comparatively similar to resin sealants, the sealing ability was satisfactory. 4. 3.3种窝沟封闭剂均显示出较低的微渗漏,同时玻璃离子材料FujiⅨGP具有与树脂类封闭剂相似的牙面密合度,封闭性好。
Which resin the enhanced glass ionomer cement and light-curing calcium hydroxide fracture surface visible resin and most of the bottom material to fall off, and clearly visible dentin surface mixed fracture. 而其中树脂增强型玻璃离子水门汀和光固化氢氧化钙断裂面可见树脂与垫底材料大部分一起脱落,并清晰可见牙本质面,为混合断裂。
