【摘要】：目的探究不同的树脂材料在桩核修复中对微渗漏程度的影响。方法对46颗经过根管治疗的单根离体牙根,分别使用纤维桩加ParaCore双固化流动树脂、可乐丽菲露AP-X光固化复合树脂以及Ceramage聚合瓷行纤维树脂桩核修复,采用根管内直接成型-直接粘接或根管外间接成型-再粘接的方法,通过染色透明化法,观察不同纤维树脂桩核修复后的微渗漏情况。结果ParaCore+根管内直接成型-直接粘接法制作的桩核微渗漏最严重[(4.94±1.71)mm],ParaCore+间接成型-再粘接法[(0.91±0.33)mm]、AP-X+间接成型-再粘接法[(0.87±0.27)mm]、Ceramage+间接成型-再粘接法[(1.02±0.34)mm]微渗漏值较低。结论不同树脂材料对纤维树脂桩核修复体的微渗漏情况无明显影响,但不同的制作及粘接方法对桩核修复体的微渗漏程度有显著影响。
[Abstract]:Objective to investigate the effect of different resin materials on microleakage in post-core restoration. Methods 46 isolated roots treated with root canal were repaired with fiber post and ParaCore double-curable flow resin, claliferol AP-X light-cured composite resin and Ceramage polymerized porcelain respectively. The microleakage of different fiber resin post and core was observed by the method of direct moulding in root canal, direct bonding or indirect molding and rebonding outside root canal, and the dyeing transparency method was used to observe the microleakage after repairing with different fiber resin post core. Results the microleakage of post core made by direct formation-direct bonding method in ParaCore root canal was the most serious [4.94 卤1.71)mm] Para Core indirect moulding and rebonding method [0.91 卤0.33)mm] AP-X indirect moulding and rebonding method [0.87 卤0.27)mm] Ceramage indirect moulding and rebonding method [1.02 卤0.34)mm] microleakage value was lower. Conclusion different resin materials have no significant effect on the microleakage of fiber resin post core restoration, but different fabrication and bonding methods have a significant effect on the microleakage degree of the post core restoration.
