Connection between a dental implant and an abutment

An abutment (2) with a base screw (3) and support ring (4) for the fixing of a dental implant (1) having a receiving hole (12) and an internally threaded hole (14), comprising an upper neck part (20);

• and a lower root part (29), which ends at a lower edge (272), an inlet (24) beginning at the lower edge (272);
• the base screw (3) having:
• a screw head (30), and a threaded shank (32), for engaging with the internally threaded hole (14) in the implant (1);
• wherein the abutment (2) has in the inlet (24) a widened portion (243), starting at the lower edge (272) and extending internally into the abutment (2) upwardly to a shoulder surface (242), the support ring (4) being positioned in the inlet (24);
• and the base screw (3) protruding through the support ring (4), wherein the support ring (4) is firmly inserted in the inlet (24), and the base screw (3), rests on the support ring (4).

A method for manufacturing an abutment (2) for connection to an implant (1), comprising the steps:

• providing an abutment (2) having a receiving hole (12) and an internally threaded hole (14), said abutment comprising further an upper neck part (20) and a, lower root part (29), which ends at a lower edge (272);
• providing a base screw (3), said base screw comprising a screw head (30) and a threaded shank (32);
• arranging a support ring (4) at said base screw (3) between said screw head (30) and said threaded shank (32);
• inserting said base screw (3) and said support ring (4) firmly into in a widened portion (243) of an inlet (24) of said lower root part (29), said widened portion (243) beginning at said lower edge (272) of said inlet (24) and extending internally upward as far as a shoulder surface (242);
• and
• fixing said support ring (4) in said widened portion (243).

• an inlet (24) beginning at the lower edge (272);
• the base screw (3) having:
• a screw head (30) and a threaded shank (32), for engaging with the internally threaded hole (14) in the implant (1);
• the support ring (4) being positioned in the inlet (24) and the base screw (3) protruding through the support ring (4), the support ring (4) being firmly inserted into the inlet (24), and
• the base screw (3) rests on the support ring (4);
• wherein the support ring (4) has a lower edge (41), said lower edge (41) is welded to the lower edge (272) of the abutment (2).
