Abstract
The implant (11) has an anchoring part (15) with an axis (13), a generally cylindrical section and a peripheral surface (21). The latter is provided, in the generally cylindrical section, with protuberances (27) which are distributed around the axis (13). At least the majority of these protuberances are elongate and parallel with the axis (13) and have at least one terminal surface which is contiguous with a recess (23) having a base formed by the peripheral surface (21). In this way, the anchoring part (15) can be pushed into a substantially cylindrical hole (2) in a bone (1) such that the implant (11) is immediately anchored in the bone (1) in a stable manner, said implant nevertheless having a high degree of strength.
