    [摘要]目的：探討含甲基丙烯酰癸基二氢磷酸酯(MDP)材料对口腔美学修复中氧化锆陶瓷粘接持久度的影响。方法：制备120个氧化钇稳定的四方相氧化锆陶瓷(Y-TZP)瓷片，氧化铝表面喷砂处理后随机分为四组(每组30个)。不含MDP的树脂水门汀为对照组，其余三组分别应用含MDP的氧化锆底涂剂(底涂剂组)、含MDP的通用粘接剂(粘接剂组)、含MDP的自粘接树脂水门汀(自粘接树脂水门汀组)，粘接Y-TZP和复合树脂，制备粘接试件。试件制成后，每组30个样本平均分为3份，分别置于37℃恒温蒸馏水中，水浴时间为24h、30d、12个月，测试试件的粘接强度，观察分析断裂模式。结果：水浴24h、30d、12个月，组间粘接强度比较：对照组水浴30d>水浴12个月(P30d of water bath>12 months of water bath (P<0.05). After 24h of water bath， control group was dominated by bond destruction， and primer group， adhesive group， and self-adhesive resin cement group were mainly mixed destruction. After 30d and 12 months of water bath， the proportion of bond destruction in each group was increased. Conclusion The application of MDP-containing materials in oral aesthetic restoration can significantly improve the bonding durability of zirconia ceramics， and the bonding durability is different among different product types. ......
