Abstract

The study was conducted to investigate how pickling affects the constitution and color of high-functional gold alloy and porcelain fusing strength with bonding porcelain during the fabrication process. Each analysis had four conditions, for the constitution and color analyses in 0-30 days, dipping the specimen in the artificial saliva, in the physiological salt solution, with pickling the oxidized specimen, and without pickling the oxidized specimen, and for the porcelain fusing strength, pickling the specimen, not pickling the specimen, with bonding porcelain, and without bonding porcelain. Gold, silver, white gold, copper, zinc, and indium were used. The analyses and results were as follows:<BR>1. Constitution analyses:<BR>A. Random point analysis on the surface: Gold, silver, and white gold chronometrically showed more constituent change under all conditions ; each showed more change than that with pickling ; and each of the other metals showed its own characteristic.<BR>B. Plane analysis on the surface: Gold, copper, and zinc showed uneven casting structure under various conditions and on various days ; indium showed it under all conditions.<BR>2. Color change analysis: The pickled specimen chronometrically showed more color change than that without pickling.<BR>3. Porcelain fusing strength analysis: The specimen with bonding porcelain showed more shear adhesive strength than that without it.<BR>In conclusion, significant data on the constitution, color, and porcelain fusing strength of the highfunctional gold alloy were obtained. Further study using the obtained data to alleviate metal allergy, harmfulness, and other related clinical problems is desired.
