Graded glass/zirconia/glass structures for damage resistant ceramic dental and orthopedic prostheses |
| abstract |
The present invention provides a functionally graded glass/ceramic/glass sandwich system for use in damage resistant, ceramic and orthopedic prosthesis. The functionally graded glass/substrate/glass composite structure comprises an outer 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. n The present invention also provides a method for preparing a functionally graded glass/ceramic/glass sandwich system. A powdered glass-ceramic composition is applied to the accessible surfaces of a presintered zirconia 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 and densifies the substrate by heating the assembly to at least the sintering temperature of the substrate. |
