An implant for an articular prosthesis comprising a first part (3) made of a polymer material defining a cavity (4) in which a second part (7) made of a ceramic material is accommodated, defining a cavity (8) which is essentially hemispherical in shape and which receives the head (2) of a second implant also comprising a rod (1), characterized in that the edge (10) of the second part (7) is buried in the first part (3) which is produced by duplicate moulding on the second part (7), also characterized in that the edge (9) of the first part (3) is provided with a chamfer (11') against which the rod (1) of the second implant is thrust. An articular prosthesis comprising a first implant and a second implant comprising a rod (1) which is terminated by substantially spherical hed (2) which turns in a cavity (8) whose shape corresponds to that of the first implant, characterized in that the first implant is of the previous type. |
