摘要:
A dental attachment assembly (100) and method anchors a dental appliance (120) with an implant (102) and has an abutment member (104) attached to the implant, a retention member (106) in releasable snap engagement with the abutment member (104), and a cap (108) secured in a recess of the dental appliance (100) and in releasable swivel engagement with the retention member (106) to position and secure the dental appliance (100) onto the implant (102). The cap (108) includes a cavity with a rounded, concave inner surface which engages with the retention member (106), an interior top surface of the cavity with a concave recess (110) extending radially along an outer periphery of the interior top surface of the cavity to allow for rotation of the retention member (106) within the cap (108). A central portion (112) of the interior top surface of the cavity surrounded by the concave recess (110) therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member (106) as it rotates.
