  • Patent number: 6283755
    Abstract: Dental implant component (1; 1′) for a dental prosthesis or a core part of a dental prosthesis to be fabricated on comprising a base section (3; 3′) having a proximal end (2; 2′) for engagement with a support end of a support component and a distal end (7; 7′); and an elongate post section (5; 5′) which projects distally from the distal end of the base section and has a transverse dimension which is substantially less than the transverse dimension of the base section. In a first aspect of the invention the dental implant component is made at least in part from a material which is adapted to burn-out during lost-wax casting whereby a dental prosthesis or core part of a dental prosthesis fabricated on the dental implant component by lost wax casting includes at most only a part of the dental implant component. In a second aspect of the invention the elongate post section is positioned offset on the distal end of the base section.

  • Patent number: 6221076
    Abstract: The invention is directed to a reamer for shaping a bone socket such as an acetabular cavity. The reamer comprises a cutting head for removing material from the socket during rotation of the cutting head. The cutting head comprises a number of relatively long main cutting edges, each of which extends in a direction from a base to a top of the reamer, and a number, higher than the number of main cutting edges, of relatively short peripheral cutting edges, which are located at the base and distributed at angulary spaced intervals about a rotational axis. The invention also provides a method for implanting a prosthesis component into a bone socket. During shaping of the bone socket, a top portion of the reamer is completely received in the bone socket to such an extent, that a cylindrical entrance portion is formed in the socket. The invention also provides a kit including a reamer and a prosthesis.
