Definitions

  • the invention relates to a device for treating a bone recess formed in the connecting region of the two legs of a tooth bifurcation, with a flat covering device which has a cell-clipping covering membrane for temporarily covering the bone recess with respect to the surrounding soft tissue, which after passing between the legs of the bifurcation in the direction of the distal end of the tooth can be bent up and, after being placed on the two tooth surfaces which are essentially parallel to the connecting line of the longitudinal central axes of the two legs, can be fastened to the tooth in the border area between dental cement and tooth enamel, the covering device on both of them the border area between tooth cement and tooth enamel corresponding spacing transverse edges has a fixing aid, characterized in that the fixing aid has a fastening device for positive and / or non-positive fixing of the covering device on tooth a uf utilizat.
  • Devices of the generic type such as those used there, generally for treating bone recesses in teeth without expressly addressing the problem of treating bifurcations, in implantology 1995; 1; Pages 21-37, are particularly difficult when they are used to treat bone recesses in the root region of bifurcal teeth, insofar as a reliable application of the covering membrane to the "inner legs" of the bifurcation cannot be easily guaranteed, whereby, especially after the gums are folded up again to the bifurcation, the covering membrane often slips, which leads to a partial opening of the bone recess. As a result, soft tissue can get into the bone recess, so that it will no longer grow through bones properly.
  • such a covering membrane which has an essentially rectangular cross-section, has been used in bifurcation treatments in such a way that the upper transverse edges of the covering membrane are held there by means of a thread or the like wrapped around the tooth, without reliably penetrating it of soft tissue in the bone recess in the connection area of the legs of the bifurcation.
  • the invention has for its object to provide a device of the generic type, which flawlessly filling the bone recess exclusively in the connection area of the legs of a tooth bifurcation guaranteed.
  • the fixing aid has a fastening device for positive and / or non-positive fixing of the covering device on the tooth.
  • the fastening device has a binding screw for passing a binding thread which is firmly connected to the covering device in at least one position.
  • the invention also proposes that the covering device has at least one of its transverse edges a form-locking projection for engaging in a depression which is present or can be provided in the border area between dental cement and tooth enamel.
  • the form-locking projection has the shape of a shoulder which projects essentially in an L-shape from the plane of the covering device in the direction of the tooth.

Abstract

L'invention concerne un dispositif permettant de traiter une cavité osseuse (20) formée dans la zone de jonction (10) des deux branches d'une fourche dentaire, qui comprend un dispositif plan de recouvrement comportant une membrane de recouvrement (18) à action cellulo-occlusive et servant à recouvrir temporairement la cavité osseuse (20) vis-à-vis du tissu mou environnant, ledit dispositif pouvant être plié vers le haut en direction de l'extrémité distale de la dent, après son introduction entre les branches (12, 14) de la fourche. Après avoir été appliqué sur les deux surfaces dentaires sensiblement parallèles à la ligne de jonction des axes médians longitudinaux des deux branches, ledit dispositif peut être fixé à la dent (16), dans la zone d'interface (22) entre le cément (24) et l'émail (26) de la dent. Sur ses deux bords transversaux distaux correspondant à la zone d'interface (22) entre le cément (24) et l'émail (26) de la dent, le dispositif de recouvrement (18) comporte un élément auxiliaire de montage. Ce dispositif se caractérise en ce que l'auxiliaire de montage comporte un dispositif de fixation (28, 30, 34) qui permet de monter, par liaison de forme et/ou de force, le dispositif de recouvrement (18) sur la dent (16).
