  • Patent number: 9545293
    Abstract: The invention relates to an implant (10) serving to receive an abutment (110). The implant (10) has a receiving opening (15) in which a connection region (115) of the abutment (110) can be inserted. The receiving opening (15) and the connection region (115) have a conical section (17) or (117) and an indexing section (18) or (118). The total conical angle equals 6 to 20° and the indexing length f of the implant (10) or the indexing length F of the abutment (110) equals at least 90% of the conical section length k of the implant (10) or of the conical section length K of the abutment (110), typically more than 1.6 mm.

  • Patent number: 6663388
    Abstract: The invention relates to a connection between a known dental implant (1) and a straight or angular abutment (2) which can be established by means of a base screw (3) and a support ring (4). The support ring (4) is fixedly introduced into the inlet of the abutment (2) near the lower edge of same, preferably by welding or by bending over of the lower edge of the abutment (2). Before insertion of the support ring (4) the base screw (3) is introduced head first into the inlet (24) from the side of the root part of the abutment. The base screw is held in the abutment (2) by the support ring (4) on which the base screw (3) rests. The threaded shank (32) of the base screw (3) engages the inner thread (14) provided for in the implant (1) and draws the abutment (2) into the receiving hole (12) of the implant (1). An angled surface of the base screw (3) and a beveled surface of the support ring (4) contact each other so that the welding seam or bent over lower edge of the abutment (2) are relieved of axial stress.
