Abstract:
A dental attachment assembly and method anchors a dental appliance with an implant and has an abutment member attached to the implant, a retention member in releasable snap engagement with the abutment member, and a cap secured in a recess of the dental appliance and in releasable swivel engagement with the retention member to position and secure the dental appliance onto the implant. The cap includes a cavity with a rounded, concave inner surface which engages with the retention member, an interior top surface of the cavity with a concave recess extending radially along an outer periphery of the interior top surface of the cavity to allow for rotation of the retention member within the cap. A central portion of the interior top surface of the cavity surrounded by the concave recess therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member as it rotates.

Claim (Index 1):
A cap of a dental attachment assembly, comprising:\n a generally cup shaped member having a central longitudinal axis, a top wall and an annular side wall extending away from the top wall, the top wall and side wall having an outer surface and a rounded, concave inner surface defining a cavity configured for swivel engagement with a retention member adapted for engagement with an abutment member attached to a tooth root, implant, or adjacent tooth and having a central longitudinal axis; the top wall having an interior top surface with a central portion which protrudes axially into the cavity and a concave recess extending radially in an annular path along an outer annular peripheral portion of the interior top surface between the protruding central portion and annular side wall, the concave recess having a first radius of curvature and having an inner periphery forming part of the protruding central portion and an outer periphery forming a first part of the inner surface of the side wall; and the concave recess and a second part of the inner surface of the side wall extending from the first part towards an open end of the rounded, concave inner surface of the cavity together forming a curve;\n wherein the curve is configured to provide swivel engagement with the retention member between a non-swiveled position in axial alignment with the central longitudinal axis of the retention member and a fully-swiveled position in which the central longitudinal axis of the cavity is at an angle to the central longitudinal axis of the retention member.
