Abstract
A dental attachment assembly has an abutment portion at the proximal end of a one-piece dental implant (an “abutment portion”), or is an abutment for attachment to a dental implant or to a bar joining two or more dental implants, and a two-part assembly including a metal cap for placement in/attachment to a dental appliance. The cap includes a flanged skirt that projects from the top surface of the cap. A second part, a plastic insert, snaps firmly inside the cap.

A dental attachment assembly, comprising:
- an abutment for attachment to a dental implant, or to a bar, the abutment having an upper end that includes an inwardly-projecting socket, and an outer surface portion projecting downwardly from said upper end, said outer surface portion projecting above the tissue level in a patient's mouth when said abutment is secured in the implant or on the bar;
- and a two-part male member attached to said abutment, the first part of said two-part male member comprising a plastic insert having bottom and top surfaces, and an outwardly-flaring flange projecting from said insert top surface, a first skirt projecting from said flange, said first skirt having a cylindrical-shaped outer surface and a bottom edge for engagement with the upper end of said abutment, and, projecting from the center of the bottom surface of said insert, a retention member comprising a head for releasable snap engagement in said socket, said retention member being tiltable, rotatable and vertically movable in said socket, the second part of said two-part male member comprising a metal cap with a top, retentive features for attachment to a dental appliance, and a second skirt that includes a bottom projecting from the top of said metal cap, said metal cap having a size and shape for a firm snap fit over said first part with said first skirt projecting below the bottom of said second skirt.
A dental attachment assembly, comprising:
- a one-piece implant that includes, at its proximal end, an abutment portion, said abutment portion having an upper end, a socket projecting inwardly from said upper end, and an outer surface portion projecting downwardly from the upper end, the outer surface portion being positioned to project above tissue level when the implant is placed in a patient's mouth;
- a two-part male member attached to the abutment portion, the first part of said two-part male member comprising a plastic insert having a top surface, an outwardly-flaring first flange projecting from said insert top surface, a first skirt projecting from said first flange, said first skirt having a cylindrical-shaped outer surface, and, projecting from the bottom surface of said insert, a retention head for releasable snap engagement, and for tillable, rotatable and vertical movement in said socket;
- the second part of said two-part male member comprising a metal cap including a top and an upper end for engagement in a recess in a dental appliance, retentive features for attachment to a dental appliance, and a second skirt including a bottom and, projecting from the top of said metal cap, said metal cap having a size and shape for a firm snap fit over said first part with said first skirt projecting below the bottom of said second skirt.
