Abstract

The effect of three adhesive metal primers on the shear bond strength of a light-cured prosthetic composite resin bonded to cobalt-chromium or silver-palladium-copper-gold casting alloy was evaluated. The adhesive metal primers used were New Metacolor opaque bonding liner, Cesead opaque primer, and 0.5% VBATDT in acetone. A newly prepared light-cured opaque resin was used to bond a light-cured veneering resin to dental alloys. The specimens were thermocycled in water for up to 20,000 cycles between 4 degrees C and 60 degrees C, and shear bond strengths were recorded. The light-cured composite resin bonded most strongly to Co-Cr alloy primed with Cesead primer and to Ag-Pd-Cu-Au alloy with the VBATDT primer. These adhesive metal primers may be clinically acceptable for bonding a light-cured prosthetic composite resin to base or precious metal.

摘要

评估了三种金属粘结剂对光固化修复复合树脂与钴铬或银钯铜金铸造合金粘结的剪切粘结强度的影响。所使用的金属粘结剂为New Metacolor不透明粘结衬层、Cesead不透明底漆以及丙酮中的0.5% VBATDT。使用新制备的光固化不透明树脂将光固化饰面树脂粘结到牙科合金上。将试件在4℃至60℃的水中进行高达20000次循环的热循环，并记录剪切粘结强度。光固化复合树脂与用Cesead底漆处理的钴铬合金以及用VBATDT底漆处理的银钯铜金合金粘结最强。这些金属粘结剂在临床上可能适用于将光固化修复复合树脂粘结到贱金属或贵金属上。
