Patent number: 9421303Abstract: Applicants have disclosed a process for fusing a biocompatible glass to a metal substrate. In the preferred embodiment, the process comprises: grit blasting a metallic substrate (e.g., titanium) to remove a surface layer of the metal; after blasting, cleaning the abrasion residue off the surface layer; blending a solvent to use as a suspension agent; creating a suspension of biocompatible and bioactive glass-coating powders in the solvent solution; depositing the suspension onto the metallic substrate; drying thoroughly the suspension-coated metallic substrate; inserting the dried, coated substrate into a non-reactive chamber, purging the chamber with an inert gas, such as pure argon; and firing the metallic substrate, inside the furnace, in the inert gas. This process forms a robust fusion between the biocompatible glass and titanium, according to preliminary test results. This process can be used for various medical and dental devices, including implants and onplants.Type: GrantFiled: March 6, 2014Date of Patent: August 23, 2016Assignee: Covalent Coating Technologies, LLCInventors: Orville G.
