Implant arrangement and device
First Claim
1. An arrangement with an implant and attachment part, in which the attachment part comprises a recessed wall and the implant includes or cooperates with a substantially cylinder-shaped portion on a spacer sleeve applied to the implant, said substantially cylinder-shaped portion constituting front parts of a spacer arranged at or on upper parts of the implant, said attachment part and said recessed wall being arranged with displaceability in a main longitudinal direction of the implant relative to an outer surface of the substantially cylinder-shaped portion, said substantially cylinder-shaped portion being expandable so that, in a given position of longitudinal displacement, it is possible to achieve interaction between the outer surface of the substantially cylinder-shaped portion and the recessed wall and thus anchoring of the attachment part to the substantially cylinder-shaped portion, wherein:
- the substantially cylinder-shaped portion comprises parts extending adjacent to one another which, during expansion, can be pressed outward in a radial direction;
the parts extending adjacent to one another are arranged with internal surfaces which combine to form an internal inner surface;
the parts extending adjacent to one another are expandable by means of a fastening screw which is provided with an outer screw surface which can cooperate with said internal inner surface, said parts extending adjacent to one another being expanded radially as a function of a position of insertion of the screw in the implant; and
the parts extending adjacent to one another have lengths which substantially correspond to or are slightly smaller than a total length of the spacer sleeve.

Abstract
In an arrangement with implant and attachment part/dental bridge, the latter comprises one or more recessed walls. The implant is designed or can cooperate with a portion which can be arranged on a spacer sleeve belonging to the implant and extends substantially parallel to the recessed wall. The attachment part and its respective recessed wall is arranged with displaceability in the main longitudinal direction of the implant relative to the outer surface of the portion. The portion is arranged to be expandable so that, in a given position of longitudinal displacement, it is possible to achieve interaction between outer surfaces of the portion and the recessed wall and thus anchoring of the attachment part to the portion or the implant. The invention also relates to a device with two or more implants and dental bridge. By means of the invention, discrepancies between dental bridge and the implants can be taken up in an effective and rapid securing principle.

12. An arrangement with an implant and attachment part, in which the attachment part comprises a recessed wall and the implant includes or cooperates with a substantially cylinder-shaped portion on a spacer sleeve applied to the implant, said attachment part and said recessed wail being arranged with displaceability in a main longitudinal direction of the implant relative to an outer surface of the substantially cylinder-shaped portion, said substantially cylinder-shaped portion being expandable so that, in a given position of longitudinal displacement, it is possible to achieve interaction between the outer surface of the substantially cylinder-shaped portion and the recessed wall and thus anchoring of the attachment part to the substantially cylinder-shaped portion, wherein:
-
the substantially cylinder-shaped portion comprises parts extending adjacent to one another and which, during expansion, can be pressed outward in a radial direction; the parts extending adjacent to one another are arranged with internal surfaces which combine to form an internal inner surface; the parts extending adjacent to one another are expandable by means of a fastening screw which is provided with an outer screw surface which can cooperate with said internal inner surface, said parts extending adjacent to one another being expanded radially as a function of a position of insertion of the screw in the implant; and the parts extending adjacent to one another are arranged, during expansion, to work with movements of ca. 3/10 mm for the purpose of preventing deformation or movements in the material of the parts extending adjacent to one another which exceed a modulus of elasticity of the material of the parts extending adjacent to one another.
