摘　　要：目的确定疗效较理想的修复深型楔状缺损的材料和方法。方法150例患者的486颗患牙随机分为3组,分别用GCFujiⅡ型玻璃离子、DyractAP复合体和夹层技术修复深型楔状缺损,修复后1、2年复查,观察临床疗效。结果修复后1、2年成功率分别为:GCFujiⅡ型玻璃离子组85.52%、75.81%,Dyract复合体组91.61%、86.26%;夹层技术组94.12%、89.51%。术后1年夹层技术组成功率高于GCFujiⅡ型玻璃离子组,2年夹层技术组和Dyract复合体组成功率均高于GCFujiⅡ型玻璃离子组(P<0.05)。结论夹层技术、DyractAP复合体用于楔状缺损修复较GCFujiⅡ型玻璃离子临床疗效较好。Objective To explore better materials and methods for restoring deep dental wedge-shaped defects. Methods 486 teeth in 150 cases with wedge-shaped defects were randomly divided into three groups which were restored with GC Fuji Ⅱ glass-ionomer,Dyract AP Cem and sandwich technique （GC Fuji Ⅱ glass-ionomer and Charisma light-cared composite resin ） respectively. Results The l-year and 2-year-after-treatment-successful rates of GC Fuji Ⅱ glass-ionomer group were 85.52% and 75.81% respectively,the Dyract AP Cem group 91. 61% and 86.26% ,the sandwich technique group, respectivdy 94.12% and 89.51%. The l-year-successful-rate of the sandwich technique group was higher than that of the glass-ionomer group. The 2-year-successfld-rates of the Dyract AP Cem and sandwich technique group were higher than that of the glass-ionomer group＇. The difference was statistically significant （ P 〈 0. 05）. Collusion The curative effects of sandwich technique and Dyract AP Cem are superior to GC Fuji Ⅱglass-ionomer＇ for restoring deep dental wedge-shaped defects.
