发明名称 CONNECTION BETWEEN A DENTAL IMPLANT AND AN ABUTMENT
摘要 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 b y 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 firs t into the inlet (24) from the side of the root part of the abutment (2). 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 threa d (14) provided for in the implant (1) and draws the abutment (2) into the receivin g hole (12) of the implant (1). An angled surface of the base screw (3) and a bevel ed 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. The above connection system is designed especially for implants (1) with a conical receiving hole (12) and internal polygon as well as abutments (2) having a complementa ry external conical shape and external polygon.
