摘要： The present invention provides a functionally graded glass/ceramic/glass sandwich system especially useful in damage resistant, ceramic dental and orthopedic prosthesis. The functionally graded glass/substrate/glass composite structure comprises an outer (aesthetic) residual glass layer, a graded glass-ceramic layer, and a dense interior ceramic. The functionally graded glass/substrate/glass composite structure may further comprise a veneer on an exterior surface. The present invention also provides a method for preparing a functionally graded glass/ceramic/glass sandwich system. A powdered glass-ceramic composition or a glass tape is applied to the accessible surfaces of a dense alumina substrate to thereby substantially cover the substrate surfaces. The glass of the composition has a CTE similar to that of the substrate material. The glass-ceramic composition is infiltrated into the dense substrate by heating the assembly to temperatures 50-700° C. below the sintering temperature of the substrate.

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 fractures 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. The residual bioactive glass or glass-ceramic layer can be further transformed to a carbonate apatite (CHA) layer by immersing in calcifying solution or simulated body fluid (SBF) with electrolyte composition similar to that of serum. The interior ceramic preferably contains yttria-tetragonal zirconia polycrystal (Y-TZP) or ceria stabilized tetragonal zirconia polycrystal (Ce-TZP) or magnesia stabilized zirconia (Mg-PSZ) or calcia stabilized zirconia (Ca-PSZ) or alumina or zirconia-alumina composites.
