目标。目的是检查由硫代磷酸甲基丙烯酸酯与磷酸甲基丙烯酸酯和/或过氧化苯甲酰组成的底漆的改性对树脂与金属的粘合强度和耐久性的影响。方法。使用由聚甲基丙烯酸甲酯粉末以及甲基丙烯酸甲酯和三丁基硼烷引发剂的混合物组成的粘合树脂将丙烯酸棒粘合到经过各种底漆处理的银钯合金（Ag-Pd）、金银合金（Au-Ag）、钴铬合金（Co-Cr）和钛（Ti）表面。将粘合样品进行 2,000 次热循环，并使用单向方差分析和 Duncan 的新多范围测试比较平均粘合强度，p < 0.05。结果。单独使用硫代磷酸甲基丙烯酸酯或磷酸甲基丙烯酸酯底漆，热循环后 AS-Pd 的键合强度显着下降 (p < 0.05)。当硫代磷酸甲基丙烯酸酯与磷酸酯单体结合使用时，耐久性显着提高（p < 0.05）。额外使用过氧化苯甲酰和热处理导致两组的耐久性显着增加（p < 0.05）；即使经过 2,000 次热循环，平均粘合强度超过 20 MPa，最低值仍保持不变。显着性。使用硫代磷酸酯和磷酸甲基丙烯酸酯以及过氧化苯甲酰的混合物实现了对牙科贵金属的最高水平的粘合强度和耐久性。这些粘合强度结果与贱金属获得的值相当。
Objectives. The purpose was to examine the effect on the bond strength and durability of a resin bond to metal of modification of a primer consisting of thiophosphoric methacrylate with phosphoric methacrylates and/or benzoyl peroxide.Methods. Acrylic rods were bonded with a luting resin consisting of poly(methyl methacrylate) powder and a mixture of methyl methacrylate and tributylborane initiator to silver-palladium alloy (Ag-Pd), gold-silver alloy (Au-Ag), cobalt-chromium alloy (Co-Cr), and titanium (Ti) surfaces treated with various primers. The bonded samples were thermocycled for 2,000 cycles and the mean bond strengths were compared using one-way ANOVA and Duncan's new multiple range test al p < 0.05.Results. Using primers of thiophosphoric methacrylate or phosphoric methacrylates alone, the bond strengths of AS-Pd decreased significantly (p < 0.05) after thermocycling. The durability was significantly improved (p < 0.05) when thiophosphoric methocrylate was used in combination with the phosphate monomers. The additional use of benzoyl peroxide and heat treatment resulted in a significant increase (p < 0.05) in the durability of two groups; the mean bond strengths over 20 MPa and the lowest Values remained unchanged even after 2,000 thermocycles.Significance. The highest level of bond strength and durability to dental noble metals was achieved using a mixture of thiophosphoric and phosphoric methacrylates and benzoyl peroxide. These bond strength results are comparable to values obtained for base metals.
