ABSTRACT There is disclosed an implant for anchoring in bone and/or fibrous connective tissue and to which a prosthesis such as a dental bridge may be connected through connecting components. The implant is of tapered design defining a wide top portion for connection to the connecting components and a narrow base. The lower bone-engaging region of the implant is provided with a porous surface into which bone may grow thereby anchoring the implant and an upper portion of the implant has a smooth surface to avoid entrapment of oral bacteria. In one embodiment, the upper portion has a larger taper angle than the rest of the implant for increased stability and stress transfer to the surrounding bone. In another embodiment, the upper surface is coated with a bioreactive coating to allow direct bonding of bone and/or soft connective tissue (gingivial tissue) thereby inhibiting epithelial migration apically.
