Definitions

  • the invention relates to the field of dental medical technology, namely in the field of dental implant systems.
  • Known dental implant systems have an implant (also “anchoring part” or, if it is provided with an (external) thread, called “screw”), which is anchored in the jawbone and can serve as artificial tooth roots.
  • the implant can for this purpose have an (external) thread on the outer surface of the endosseous region, that is to say the region which is intended to be sunk in the bone.
  • dental implant systems can have an attachment (also called “abutment”) for attachment to the implant, on the part of the implant protruding from the gum or, if present, the abutment (if appropriate, called “post” or “head”)
  • the implant particularly an implant for connection to an abutment, may be designed to be approximately flush with the bone surface (a so-called “bone-level”) "implant).
  • the implant may have an area adapted to remain coronal to the bone surface.
  • Such implants are so-called “tissue-level” implants, which are designed to be approximately flush with the soft tissue insurance.
  • the transmucosal area of the implant can be widened in relation to the endosseous area (this shape is also called “tulip”.)
  • Another specific example of a tissue-leveP implant is a so-called monotype implant, which is set up in the implanted state, to protrude beyond the mucosal area and, for example, to receive a crown or an outer sleeve (eg for the bridge restoration) directly, ie without the use of an abutment
  • monotype implants 1-part implants in which implant and posts or implant and head are made in one piece, ie the implant continues at the soft tissue border without any attachment to the post or into the head.
  • a prosthetic component may be designed as an abutment
  • a prosthetic component may be designed as a crown or as an outer sleeve (for example, for the bar supply).
  • the prosthetic component can be fastened with a positioning screw or an occlusal screw in the implant.
  • the implant may have an opening on the coronal end face, which may have an (internal) thread for receiving the screw.
  • the prosthetic component may have structural features for receiving the screw, for example an opening.
  • a problem of conventional dental implant systems is the lack of mechanical stability of the implants, especially those of reduced diameter.
  • hairline cracks and fractures can occur on the wall of the implant, which, for example, under the influence of horizontal forces (ie forces that act substantially perpendicular to the implant axis) and the Torques generated thereby can arise.
  • Micro-movements can lead to a leaching of the connection between the components involved and thus cause damage, in particular of the implant in the course of gestation.
  • vertical forces which may arise, for example, when attaching the prosthetic component or under functional loading when chewing, are able to affect the mechanical stability of the implant. This problem can be exacerbated in particular when an extension of the prosthetic component engaging in the implant has the shape of a cone and consequently can exert a wedge effect with a spreading effect on the implant wall.
  • Another problem with known dental implant systems is a potential loss of retention between the implant and the prosthetic component. This complication is especially detrimental when the prosthetic component is under a cemented restoration, thus obstructing access to the positioning screw.
  • Another problem known dental implant systems are gaps between implant and prosthetic component. Reduction of such gaps is desirable from both a biological and a microbial perspective.
