Latest Patents
Henrietta holds 1 patent for her invention titled "Bonding agent for fusing porcelain to nonprecious metal alloy." This patent describes an extremely effective agent that achieves optimum bonding between a nonprecious dental alloy and porcelain. The bonding agent is applied in slurry form and fired to prepare the alloy's surface for bonding. It consists of major proportions of fine gold powder, porcelain, liquid flux, and a minor amount of fine zirconium oxide. The liquid flux, which can be a low fusing flux dissolved in a liquid vehicle like glycerine or alcohol, reacts with the porcelain and the oxides formed on the alloy during firing. This reaction produces a low solubility, highly tenacious, adherent intermediate layer of oxides, allowing porcelain to firmly adhere during subsequent applications and firings.
