  • Patent number: 10449020
    Abstract: Certain embodiments of the invention relate to a method of manufacturing a dental bridge. In certain embodiments of the method, a pre-sintered blank made from a green body of ceramic material is subjected to a machining operation that transforms the blank into an intermediate product with a bridge structure and a support body linked to the bridge structure by one or several retaining sections that extend from the support body to the bridge structure. In certain embodiments, a sintering operation is then performed on the intermediate product while the retaining section(s) still link(s) the support body to the bridge structure.

  • Patent number: 9375295
    Abstract: In an arrangement for obtaining reliable anchoring of a threaded implant in dentine, a hole is made in the bone substance. In the side wall of the hole it is possible to establish an internal threading which can cooperate with an external threading on the implant. The implant threading is arranged to force the bone substance out in essentially radial directions as a function of the extent to which the implant is screwed into the hole. The threading is arranged to effect greater forcing out of the bone substance at the outer parts of the hole than at the inner parts of the hole. The degree of forcing out is adapted in relation to the softness of the bone in order to achieve the reliable anchoring. Along at least part of the longitudinal direction of the implant, the implant threading can be given a non-circular configuration for the purpose of obtaining improved rotational stability in soft/weak bone.

  • Patent number: 9259299
    Abstract: In certain embodiments, a combination of a thread forming tool and an implant is disclosed. The thread forming tool can have a thread forming section with a helical thread having at least one cutting surface for cutting a thread in bone. The implant can include a bone apposition surface having at least one helical thread for position at least partially in the thread of the bone. A longitudinal cross-sectional shape of at least a portion of the helical thread of the thread forming section in certain embodiments, substantially corresponds to a longitudinal cross-sectional shape of at least a portion of the helical thread of the implant.

  • Patent number: 9125708
    Abstract: A medical implant and a method of implanting a medical implant are described. In some embodiments, the medical implant can include an apical bone anchoring portion for bone apposition, and an unthreaded coronal portion.

  • Patent number: 8915735
    Abstract: In an arrangement for obtaining reliable anchoring of a threaded implant (3) in dentine, a hole (2) is made in the bone substance. In the side wall (2b) of the hole it is possible to establish an internal threading which can cooperate with an external threading (3d) on the implant. The implant threading is arranged to force the bone substance out in essentially radial directions as a function of the extent to which the implant is screwed into the hole. The threading is arranged to effect greater forcing out of the bone substance at the outer parts of the hole than at the inner parts of the hole.
