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.
