Abstract: A dental attachment system has an abutment member configured for attachment to a tooth root, implant, or adjacent tooth, the abutment member having a head and an annular seat adjacent the head. An elastomeric ring is configured for releasable engagement in the seat on the abutment member, and is retained in a retainer ring which in turn is in swivel engagement with a concave inner surface of a cavity in a cap which is secured in a recess in a dental appliance such as a denture, partial denture, or the like.

Abstract: An implant bar attachment system and method includes an elongate bar for extending between at least two implant sites and at least two fastener devices at opposite ends of the bar for securing the bar to the respective implants. The bar has socket formations for snap engagement with the heads of respective male members secured to an overlying denture. At least some of the socket formations are provided in the heads of female fastener devices which extend through bores in the bar at respective implant sites for connection to an implant or implant abutment, so that the denture attachment point is coaxial with the implant.

Abstract: A multiple part anchor assembly is designed for attaching a dental appliance to a non-vital tooth root or an implant, and has a female part for attachment to a tooth root or implant, a male part or stud having a first end for releasable snap engagement in a socket in the female part with some relative movement permitted between the parts, a cap for securing in a recess in a dental appliance having a second socket, and the male part having a swivel joint at its opposite end for engagement in the second socket to secure the root or implant to the appliance, the hinge joint allowing hinging of the stud relative to the cap.

Abstract: An attachment structure for securing a denture in an oral cavity comprises an insert member for securing to the denture and a retainer member for mounting in a cut-out in an existing tooth. One of the members has an elongate channel and the other member has a corresponding elongate tongue for sliding engagement in the channel in the direction of insertion of the denture in the oral cavity. The channel and tongue have cooperating interengageable snap-fit formations at their lower end which are elongated in a direction transverse to the tongue and channel.

Abstract: A snap-in anchor for a denture, including an open-sided sleeve with a socket at one end, which is inset and secured directly in an existing tooth. A snap pin with an enlarged head is embedded in the denture by a retaining lug extending from the pin, the denture being anchored by sliding the pin into the sleeve and snapping the head into the socket. The sleeve has resilient side walls that frictionally grip the entire length of the pin for stability but that allow very limited movement of the denture to accommodate jaw motions.
