目的
本研究的目的是评价金属调节剂和表面改性系统用于假体复合材料和钛合金之间粘合时的粘合性能。
材料和方法
评估了8种金属调节剂（Acryl Bond、All-Bond 2底漆B、合金底漆、Ces II不透明底漆、Eye Sight不透明底漆、Metafast粘合衬垫、金属底漆II和MR Bond）和粘合系统（Siloc）。由钛合金（Ti-6Al-7 Nb，T-Alloy坚韧）制成的铸造圆盘样本使用8种底漆中的一种进行底漆处理，或使用Siloc系统进行处理，并使用光激活假体复合材料（Artglass）进行粘合。在热循环（4 ℃-60 ℃，每次60秒，20，000次循环）之前和之后测定剪切粘结强度，以评价粘结的耐久性。
结果
结果表明，Siloc处理组记录了最大的热循环后粘结强度，其次是用Cesead II不透明底漆和合金底漆试剂调节的两个组，这两个试剂都含有相同的疏水磷酸盐-甲基丙烯酸酯官能单体。
PURPOSE
The purpose of the current study was to evaluate the adhesive performance of metal conditioners and a surface modification system when used for bonding between a prosthetic composite material and a titanium alloy.
MATERIALS AND METHODS
Eight metal conditioners (Acryl Bond, All-Bond 2 Primer B, Alloy Primer, Ces II Opaque Primer, Eye Sight Opaque Primer, Metafast Bonding Liner, Metal Primer II, and MR Bond) and a bonding system (Siloc) were assessed. Cast disk specimens made of a titanium alloy (Ti-6Al-7Nb, T-Alloy Tough) were either primed with one of the eight primers or treated with the Siloc system and bonded with a light-activated prosthetic composite material (Artglass). Shear bond strengths were determined both before and after thermocycling (4 C-60 C, 60 s each, 20,000 cycles) for evaluation of the durability of the bonds.
RESULTS
The results showed that the Siloc-treated group recorded the greatest post-thermocycling bond strength, followed by the two groups conditioned with the Cesead II Opaque Primer and Alloy Primer agents, both of which contain an identical hydrophobic phosphate-methacrylate functional monomer.
