目的:测定两种玻璃离子水门汀不同加压时间的即刻粘接强度。方法:对70颗离体牙进行牙体预备,暴露牙本质,随机分为2组:KetacTM Cem Easymix玻璃离子水门汀组(3M组)、TOKUSO玻璃离子水门汀组(TOKUSO组);每组根据加压时间不同再分为7个小组...目的:测定两种玻璃离子水门汀不同加压时间的即刻粘接强度。方法:对70颗离体牙进行牙体预备,暴露牙本质,随机分为2组:KetacTM Cem Easymix玻璃离子水门汀组(3M组)、TOKUSO玻璃离子水门汀组(TOKUSO组);每组根据加压时间不同再分为7个小组,应用玻璃离子水门汀将钴铬合金铸件与牙本质粘接后分别加压5,10,15,20,25,30,35min,测定即刻拉伸强度值。结果:两种玻璃离子水门汀对于钴铬合金与牙本质在加压不同时间后的即刻粘接强度比较差异均有显著性意义(P<0.01),均在加压25min后测得的即刻粘接强度最大。3M加压25min组比TOKUSO加压25min组粘接强度大,但是二者之间差异无显著性意义。结论:KetacTMCemEasymix玻璃离子水门汀、TOKUSO玻璃离子水门汀临床应用时均应加压至25min,以获得最大粘接强度。展开更多
