Abstract

An adhesive opaque resin for veneering on cast metal was developed with 4-methacryloxyethyl trimellitate anhydride and poly (methyl methacrylate)-coated titanium dioxide prepared by aqueous phase polymerization. The opaque resin was a modified 4-META/MMA-TBB resin. The powder consisted of 20% of the encapsulated material and 80% PMMA instead of pure PMMA powder. This resin hides the metal color when the thickness of the resin is as thin as 50 microns. The opaque resin bonded strongly to both cobalt-chromium alloy and visible-light-cured veneering resin. This self-curing opaque resin is applicable not only for bonding veneering resin to an alloy surface but also for bonding fixed partial dentures to enamel surfaces.

摘要

一种用于铸造金属贴面的粘性不透明树脂由偏苯三酸酐-4-甲基丙烯酰氧基乙酯和通过水相聚合制备的聚（甲基丙烯酸甲酯）包覆的二氧化钛制成。该不透明树脂是一种改性的4-META/MMA-TBB树脂。粉末由20%的包囊材料和80%的聚甲基丙烯酸甲酯组成，而不是纯聚甲基丙烯酸甲酯粉末。当树脂厚度薄至50微米时，这种树脂就能遮盖金属颜色。该不透明树脂与钴铬合金和可见光固化贴面树脂都能牢固粘结。这种自固化不透明树脂不仅适用于将贴面树脂粘结到合金表面，也适用于将固定局部义齿粘结到牙釉质表面。
