Abstract

This study evaluated the effect of luting system with acidic primers on the durability of bonds with Ti-15Mo-5Zr-3Al titanium alloy (Ti-15Mo-5Zr-3Al) and its component metals. Adherend metals were Ti-15Mo-5Zr-3Al, Ti, Mo, Zr, and Al. Four primers were evaluated as adhesion promoters: Alloy Primer (ALP), Estenia Opaque Primer (EOP), M. L. Primer (MLP), and Super Bond liquid (SBL). An acrylic resin was used as the luting material. Pre- and post-thermocycling shear bond strength was determined to evaluate the bonding durability, and the results were compared using non-parametric statistical analyses (n=11/group). The post-thermocycling bond strength in MPa (median) associated with ALP, EOP, MLP, and SBL were 18.8, 19.8, 4.1, and 0.8, respectively, for Ti-15Mo-5Zr-3Al. The results showed that two primers containing 10-methacryloyloxydecyl dihydrogen phosphate (MDP) were effective for the durability of bonding of Ti-15Mo-5Zr-3Al to the resin. MDP enhanced the bonding durability of the resin bonded to either Ti, Zr, or Al.

摘要

本研究评估了含酸性引物的水门汀系统对 Ti-15Mo-5Zr-3Al 钛合金（Ti-15Mo-5Zr-3Al）及其组成金属与树脂黏结耐久性的影响。被粘金属为 Ti-15Mo-5Zr-3Al、Ti、Mo、Zr 和 Al。评估了 4 种引物作为黏附促进剂：Alloy Primer（ALP）、Estenia Opaque Primer（EOP）、M. L. Primer（MLP）和 Super Bond liquid（SBL）。采用丙烯酸树脂作为水门汀材料。通过热循环前后剪切黏结强度来评估黏结耐久性，并采用非参数统计分析（每组 n=11）进行比较。ALP、EOP、MLP 和 SBL 与 Ti-15Mo-5Zr-3Al 相关的热循环后黏结强度（MPa，中位数）分别为 18.8、19.8、4.1 和 0.8。结果表明，两种含有 10- 甲氧基丙烯酰氧基二氢磷酸酯（MDP）的引物对 Ti-15Mo-5Zr-3Al 与树脂的黏结耐久性有效。MDP 增强了树脂与 Ti、Zr 或 Al 黏结的耐久性。
