An implant for replacing a tooth or another part of bony tissue comprises a first non-resorbable layer (2) containing a bioglass, e.g., CaP-glass; a second layer (4) of a mixture of bioglass and hydroxyl apatite resorbable into bone or biomass, and a slowly resorbable intermediate layer (3) containing bioglass and being disposed between said first and second layers; the inclusion of said hydroxyl apatite into the second layer (4) securing the stability of bonding of the implant to the tissue. When strength is required, the implant further comprises a metal core (1) to which the first layer (2) is attached. The materials may also be used as a granule filler in bone cavities and as a block for the replacement of bone. |
