Definitions

  • the inventive alignment of the channel-shaped recesses 9 ensures that the implant 1 can not loosen in the unlocking, but is additionally fixed, and that the recesses 9 when screwing the implant 1 into the bone no Represent obstacles that could complicate the insertion of the implant 1.
  • the inventive alignment of the recesses 9 is further ensured that the openings 10 do not clog when screwing the implant 1 and thus can fulfill their purpose as access to the surrounding bone tissue.
  • an internal thread 11 is arranged as a fastening element 12 in the bore 4.
  • a conduit, an access tube, a screw, a mandrel and / or a plug may be attached to the fastener 12.
  • a screw or a screw mandrel can be screwed into the internal thread 11, so that the apical end 8 can either be closed or provided, for example, with an access line for introducing substances and / or cells into the periapical space.
  • the bore 4 has in the vicinity of the apical end 8 as an additional fastening element 12, a further internal thread 15 on which also a conduit, an access tube, a screw, a mandrel and / or a plug can be attached.
  • the shaft region 2 or the bore 4 can be subdivided into different compartments 16, 17, 18.
  • the individual compartments 16, 17, 18 are sealed against each other so that a targeted application to different levels of the surrounding tissue on the respective perforations 9 is made possible.

Abstract

L'invention concerne un implant (1) et/ou une vis à os présentant au moins une partie tige (2) et au moins une partie filetée destinée à être vissée dans une structure osseuse, la partie tige (2) et/ou la partie filetée présentant au moins un évidement (9) et/ou au moins une saillie. Selon l'invention, les évidements (9) sont orientés vers l'extrémité distale (6), contre le sens de vissage. L'axe longitudinal des évidements (9) est environ parallèle au pas du filetage du filet extérieur non représenté. Cette orientation des évidements (9) permet de garantir que l'implant (1) ne se libère pas dans le sens de dévissage, mais qu'il peut être fixé de façon supplémentaire, et que la matière osseuse n'est pas comprimée dans les évidements (9) lors du vissage.
