Definitions

  • the invention relates to a dental prosthesis with an implant body and with an insertable into a receptacle of the implant body abutment, which forms a passage opening for receiving a engaging in a female thread of the implant body cap screw and carries a tooth structure against rotation.
  • an implant body When using a dental prosthesis usually an implant body is inserted into the jawbone and provided with an abutment for receiving a tooth structure, such as a dental crown.
  • This abutment is connected by means of a cap screw with the implant body, which is inserted into a through hole of the abutment and engages in a female thread of the implant body.
  • the screw head is supported on an annular shoulder of the abutment, wherein the requirement is that the head screw can not accidentally come loose and allows a tight connection to the abutment, so that no bacteria can reach the implant body.
  • the invention is therefore the object of a dental prosthesis of the type described in such a way that a secure screw connection between the abutment and the implant body in each rotational position of the cap screw can be ensured over longer periods of time.
  • the invention achieves the stated object in that the head of the cap screw is positively connected to a rotatable only together with the cap screw rotation, which is glued to the tooth structure
  • the cap screw By providing a form-locking connected to the head screw head rotation lock the cap screw can only be rotated together with the anti-rotation, so given a rotationally fixed holding the anti-rotation security that the cap screw can not relax.
  • the non-rotatable mounting of the rotation lock takes place in a simple manner via an adhesive connection of the rotation lock with the tooth structure, which must be kept so twist-proof on the abutment, usually via an adhesive layer. With the non-rotatable support of the anti-rotation against the tooth structure thus loosening the cap screw is effectively prevented.
  • this security against rotation of the cap screw can Abutment be changed if necessary, because after removal of the tooth structure by releasing the adhesive connection and removing the anti-rotation of the head screw is freely accessible again.
  • cap screws for the connection of the abutment with the implant body generally have a plug-in receptacle for an operating tool in the form of a hexagon socket of the head, particularly simple construction conditions arise when this plug-in receptacle is used for the positive connection of the screw head with the anti-rotation device, because in this case the rotation lock can be designed as a simple insert, which engages positively in the provided for an operating tool plug-in receptacle of the head of the cap screw.
  • the anti-rotation device closes flush with the abutment, then advantageous adhesive conditions result, since no consideration has to be given to the gluing of the anti-rotation device with the tooth structure in the design of the tooth structure.
  • the anti-rotation device forms an adhesive surface which largely closes the through-opening of the abutment, so that no bacteria can reach the implant body between the tooth structure and the anti-rotation device with an adhesive layer bridging the annular gap between the anti-rotation device and the abutment.
  • an inventive dental prosthesis is shown in a schematic longitudinal section.
  • the dental prosthesis according to the exemplary embodiment has, in a conventional manner, an implant body 1 that can be inserted into the jawbone for receiving a Nes abutment 2, which serves as a carrier for a tooth structure 3, which consists in the embodiment of an implant crown.
  • a Nes abutment 2 which serves as a carrier for a tooth structure 3, which consists in the embodiment of an implant crown.
  • the connection between the abutment 2 and the implant body 1 via a cap screw 4, which is inserted into a through hole 5 of the abutment 2 and engages in a female thread 6 of the implant body 1.
  • the head 7 of the cap screw 4 is supported on an annular shoulder 8 of the abutment 2, so that the abutment 2 can be connected to the implant body 1 in a tensile-resistant manner via the cap screw 4.
  • a rotation lock 9 is provided for the cap screw 4, which is positively connected to the head 7 of the cap screw 4.
  • This anti-rotation device 9 is advantageously formed as an insert 10 which engages positively with a plug-in projection 1 1 in the plug-in receptacle 12 of the head 7 for an actuating tool.
  • This plug-in receptacle 12 is usually shaped as a hexagon socket, so that the plug-in approach 1 1 has a corresponding hexagonal cross-section.
  • the rotation lock 9 can be held in a simple manner against the abutment 2 rotatably, the rotation lock 9 is glued to the front side with the tooth structure 3, which in turn is glued to the abutment 2.
  • the adhesive layer 13 is indicated by dash-dotted lines schematically. Since the front side of the rotation lock 9 is flush with the abutment 2, there is a through the opening 5 of the abutment 2 substantially continuous adhesive surface between the tooth structure 3 and the rotation lock 9, so on the adhesive layer 13, the rotation lock 10 rotatably held against the abutment 2 becomes.

Abstract

La présente invention concerne une prothèse dentaire comprenant un corps d'implant (1) et un pilier (2) qui peut être inséré dans une partie de réception du corps d'implant (1), forme une ouverture de passage (5) destinée à recevoir une vis à tête (4) qui vient en prise dans un filetage d'écrou (6) du corps d'implant (1) et porte de manière anti-rotative une superstructure de dent (3). Pour garantir des conditions de réalisation simples, la tête (7) de la vis à tête (4) est selon l'invention reliée par complémentarité de forme à un élément de blocage en rotation (9) qui ne peut tourner qu'avec la vis à tête (4) et qui est collé à la superstructure de dent (3).
