Definitions
- FIG. 5 is a schematic cross-sectional view of the teeth of the implant shown in FIG. 1;
- FIG. 6 is a top view of a portion of the teeth on an upper surface of the implant;
- the space defined by the central opening 14 (best viewed in FIG. 2) openings are preferrably filled with hydroxyapatite combined with any biological factor or composition which helps to induce growth of bone and cartilage against the surface of the implant and in the spaces defined by the teeth 19.
- the implant 10 optionally includes an insert of synthetic bone material, such as porous hydroxyapatite or other equivalent substance.
- synthetic bone material is Interpore ProOsteon 500 brand of porous coralline hydroxyapatite, available from
