    摘要: The present invention provides a functionally graded bioactive glass/ceramic composite structure or bioactive glass/ceramic/bioactive glass sandwich structure for use in such applications as damage resistant, ceramic dental implants, immediate tooth replacement, endodontic posts, orthopedic prostheses, orthopedic stems, bone substitutes, bone screws, plates, and anchors, nonunion defects repair, alveolar ridge augmentation, missing small bone parts (e.g. fingers, toes, etc), maxilla facial reconstruction, spinal fusion, and scaffolds for bone regeneration, comprising a residual bioactive glass or glass-ceramic layer at all accessible surfaces, followed by an underlying graded glass-ceramic layer, and then an dense interior ceramic. Further, the invention provides methods for making the same structure.

    摘要: An adherent bioactive calcium phosphate coating is formed on a titanium or titanium alloy substrate by immersing the substrate in an acidic calcium phosphate solution to form a non-apatitic calcium phosphate coating on the substrate. In a second step the coated substrate can be converted to a less reactive coating by being immersed into a basic or neutral solution to convert the coating into an apatite. However if a relatively reactive coating is desired, the second step can be dispensed with.
