Definitions

  • the present invention relates in general to the field of dental implant technology, and more particularly to abutment systems used to connect the implant anchor to a prosthetic device. More specifically, the invention relates to retention features used by an abutment system to resist loosening of the abutment.
  • Dental implants are commonly used as anchoring members in prosthodontic restorations to provide prosthetic teeth at one or more edentulous sites in a patient's dentition at which the patient's original natural teeth have been lost or damaged.
  • known implant systems include a dental implant made from a suitable biocompatible material, such as titanium.
  • the dental implant is typically threaded into a bore which is drilled into the patient's mandible or maxilla at the edentulous site.
  • the implant provides an anchoring member for a dental abutment, which in turn provides an interface between the implant and a dental prosthesis.
  • the small size of the components of abutment assemblies make it difficult to install the abutment screws in the assemblies, which can lead to over-torquing of the screws facilitating failure.
  • yielding may lead to a loss of preload tension in the connection, causing relative motion between the joined components and compromising the function of the prosthesis.
  • These stress concentrations are compounded by the physical size restraints placed on prosthetic components.
  • the materials which are available to the implant designer such as, polymers, metals, and composites, quite often exhibit creep characteristics. The stress-raising factors encountered in implants aggravate the tendency of these materials to have time- dependent strain at stress levels below yield.
  • the most common form of attachment currently in use is a small screw which passes through the abutment and threads into the implant anchor body.
  • This abutment screw works in conjunction with a hex feature on the exterior or interior of the implant anchor body.
  • the combination of the hex feature and screw fastening secure the abutment in place and provide for anti-rotation of the abutment in relation to the implant.
  • the hex feature is also used as a wrenching surface to install externally threaded implants into the mandible or maxilla.
  • Gersberg in U.S. Pat. No. 5,195,892 discloses an internally splined implant anchor adapted for receiving a cooperatively splined prosthetic support structure .
  • a threaded fixation screw secures the abutment into the implant in a conventional manner.
  • an abutment system that is comprised of an implant anchor with a socket located at the attachment end of the implant anchor, an annular protrusion located inside the implant cavity and below the socket, and an abutment having a connector located at the attachment end of the abutment.
  • the connector is configured to be fitted into the socket of said implant anchor.
  • Said connector is comprised of at least two bendable sections separated from each other by a slot and an annular groove located on the outer surface of the connector end.
  • the annular protrusion of the implant anchor is configured to be fitted into the annular groove of the connector thus forming a snap connection between said implant anchor and the abutment

  • FIG. IB is sectional view of a snap lock mechanism of the abutment system of the present invention.
  • FIG. 2 A is a perspective view of an abutment of the abutment system of the present invention.
  • FIG. 2B is a side view of an abutment of the abutment system of the present invention.
  • FIG. 2C is a sectional view of an abutment of the abutment system of the present invention.
  • FIG. 3 is a sectional view of an implant anchor of the abutment system of the present invention.
  • the abutment system 10 is comprised of three main components: an implant anchor 200, an abutment 100, and a locking screw 300.
  • Implant anchor 200 is generally osseointegrated into a targeted human bone as, for example, a jaw bone.
  • the structure of the inferior end of the implant anchor 200 may be a root-form implant or a blade-form implant.
  • the implant may be also manufactured in any of the following forms to promote bone growth and regeneration: threaded screw-type, cylindrical, stepped surface, hollow cylindrical baskets, or blades.
  • the insertion end of the implant may be configured to be self- tapping or tapered to mate with a pre-tapped hole in the jaw bone.
  • the implant 200 is conformed for a mating engagement with the abutment 100.
  • the attachment end of the implant 204 includes a hexagonal socket 201 having a depth of a hexagonal socket of a standard implant.
  • the abutment 100 includes a hexagonal connector 101, located at the attachment end 102 of the abutment 100.
  • the hexagonal connector 101 tightly fits into a
  • the connector 101 and the socket 201 may have a shape other than hexagonal.
  • the hexagonal connector 101 is comprised of at least two bendable sections 103, separated from each other by a slot 105.
  • the sections 103 create the overall hexagonal shape of the connector 101.
  • the abutment 100 Upon the insertion of the connector 101 into the socket 201, the abutment 100 is secured to the implant 200 by a snap lock mechanism activated between the socket 201 and the connector 101.
  • the snap lock mechanism is comprised of an annular protrusion 202, located inside the implant cavity 203 and below the socket 201, and an annular groove 104 located on the outer surface of the connector end 108.
  • the annular protrusion 202 is configured to be fitted into an annular groove 104 of the connector 101.
  • the abutment 100 also includes a cavity 107 that has an extraction thread 106.
  • a driver key is used for the extraction of the abutment 100 from the implant 200. The rotation of the threaded portion of the driver key inside the thread 106 forces driver key shaft against the bottom surface of the implant cavity 203, thus creating an opposite force acting upon the abutment 100 and causing its extraction from the implant 200.
  • the abutment 100 could be used with other standard implants, as the hexagonal connector 101 could be easily fitted into a hexagonal socket of the standard implant.
  • the implant 200 could be used with the standard abutments, because a hexagonal connector of the standard abutment could be easily fitted into the hexagonal socket 201.

Abstract

La présente invention concerne un système de butée (10) qui est composé d'un ancrage pour implant (200) avec une emboiture (201) située au niveau de l'extrémité de fixation (204) de l'ancrage d'implant (200), une protubérance annulaire (202) située à l'intérieur de la cavité d'implant (203) et en dessous de l'emboîture (201), et une butée (100) ayant un raccord (101) situé au niveau de l'extrémité de fixation (102) de la butée (100). Le raccord (100) est configuré pour être ajusté dans l'emboîture (201) dudit ancrage d'implant (200). Ledit raccord (101) est composé d'au moins deux sections pouvant être pliées (103) séparées l'une de l'autre par une fente (105) et un sillon annulaire (104) situé sur la surface extérieure de l'extrémité de raccordement (108). La protubérance annulaire (202) de l'ancrage d'implant (200) est configurée pour s'ajuster dans le sillon annulaire (104) du raccord (101) formant ainsi un raccord par emboîtement entre ledit ancrage d'implant (200) et la butée (100).
