Abstract
The present invention relates generally to the field of dental implant systems. More specifically, the invention relates to implant anchors with an internal screw portion and an exterior body with threaded and non-threaded portions. Even more specifically, the invention relates to an implant anchor with novel features to prevent leakage between components and vent liquids, compressed air, and biological materials, the implant anchor having a compatibility with a line of implant components.
Claims21
An implant anchor, the anchor extending between a basal end placed into bone and a corona, the anchor comprising the following distinct regions:
- a shaft comprising a non-threaded portion and a threaded portion, the threaded portion disposed between the basal end and the non-threaded portion, the threaded portion comprising a macro-threaded portion and a micro-threaded portion, the micro-threaded portion disposed between the macro-threaded portion and the non-threaded portion, the non-threaded portion positioned between the macro-threaded portion and the corona of the implant anchor;
- a non-curved external surface disposed between the non-threaded portion and the corona;
- a coronal face located at the corona of the anchor and interior of the non-curved external surface;
- a mating orifice having distal peaks that breach the non-curved external surface;
- an internal cavity of the implant anchor, the internal cavity opening at the mating orifice, the internal cavity comprising an anti-rotational mating chamber, a rotational mating chamber, a conduit, and internal threads, the anti-rotational mating chamber and the rotational mating chamber positioned coronally of the internal threads and the mating orifice, the conduit traveling from the internal cavity to the non-curved external surface;
- and
- the conduit connecting the non-curved external surface to the internal cavity.
A dental implant system for securing an implant component onto an implant anchor, the system comprising:
- the implant anchor having a corona and a basal end, the anchor comprising;
- a) a shaft extending from the basal end,
- b) a non-curved external surface between the shaft and the corona, the non-curved external surface having portions defined by distal peaks of an anti-rotational mating orifice;
- c) an internal cavity of the implant anchor having internal threads, the anti-rotational mating orifice extending into the internal cavity;
- d) an coronal face at the corona, the coronal face having a rotational mating orifice, the rotational mating orifice extending into the internal cavity;
- and
- the implant component comprising:
- a) a component sealing interface, wherein the non-curved external surface and the component sealing interface seal upon a coronal edge of the non-curved external surface;
- and
- b) a threaded shaft that screws into the internal threads of the internal cavity of the implant anchor during seating of the implant component onto the implant anchor, whereby the component sealing interface mechanically seals from the coronal edge inward, applying an axial and coronal force to the component that locks the threaded shaft into the internal threads of the internal cavity.
