Definitions

  • the present invention relates to anchoring for insertion into tooth roots for denture abutments, the use thereof for supporting denture abutments with bimetallic contacts, the use thereof for supporting denture abutments with a permanent magnet holder, and a denture abutment.
  • the present invention aims to provide anchoring of the type mentioned at the outset, which prevents the occurrence of contact potential differences at the anchoring base.
  • it is characterized in that at least the part to be let into the root is galvanically insulated from the outside.
  • An inexpensive simple anchoring results from the fact that it consists of insulating material, preferably of kerami.
  • Fig. 1 shows a schematic ' longitudinal section through a
  • FIG. 3 shows a schematic longitudinal section through a tooth root with anchoring and a permanent magnet-retained prosthesis attached to it.
  • FIG. 1 schematically shows a tooth root 1 whose end protruding from the gum 3 has been prepared by appropriate grinding for the reception of a denture structure, be it a bar or directly a prosthesis.
  • a denture structure be it a bar or directly a prosthesis.
  • an anchoring channel 5 is drilled into the tooth root by means of a standard drill, in which case the actual anchoring 7 is then inserted and fastened.
  • the denture structure is then attached to this anchor 7.
  • the anchoring 7 is now designed in such a way that it is galvanically insulated from the outside at least on its part 7a to be inserted into the root.
  • FIG. 2a in a first embodiment ⁇ variant it comprises an entirely insulating material, preferably anchoring body 9 consisting of a ceramic material, which is at least almost cylindrical in form for anchoring into an anchoring channel 5 of FIG. 1.
  • anchoring body 9 consisting of a ceramic material, which is at least almost cylindrical in form for anchoring into an anchoring channel 5 of FIG. 1.
  • the body 9 has, for example, a smooth or threaded fastening bore 11, or else a fastening part 13, for example an external thread, on its outer wall.
  • the essential thing can be seen in the fact that the body 9 is galvanically insulated from the outside, according to the embodiment in FIG. 2a, consists entirely of insulation material.
  • the body 9 consists of a metallic tube 15, which at the part 9a which is intended to be let into the tooth root, with an insulating coating 17, for example a plastic coating, but preferably with a ceramic coating, is provided.
  • an insulating coating 17 for example a plastic coating, but preferably with a ceramic coating.
  • a dental prosthesis structure with the aid of permanent magnets directly or indirectly on the anchorages described in FIG. 3, generally designated 9.
  • a first metal cap 19 is attached to the anchoring 9, which acts as a permanent magnet with poles N. and S. At a protest
  • a further metallic insert 23 is attached, also as a permanent magnet with the poles S 2 and N_.
  • the prosthesis 21 can be placed on the anchoring 9 provided with the magnetic attachment 19 and held by the magnetic effect of the parts 19 and 23.
  • Such a connection of the denture abutment with the anchoring is on the one hand sufficiently stable according to the intended magnetic force, and also enables the abutment to be removed by the patient 10 himself, so that an optimal also on the tooth root neck Cleaning can be done.

Abstract

L'ancrage (9) destine a etre introduit dans les racines des dents est isole galvaniquement vers l'exterieur au moins sur sa partie introduite dans la racine (1) pour eviter que des tensions au contact galvanique ne se forment dans le milieu electrolytique. Ainsi, des courants entre l'ancrage et le tissu environnant sont supprimes de facon qu'aucune destruction de tissus n'ait lieu et qu'aucune formation d'agents toxiques ne se manifeste. Par consequent, lors du choix de materiaux pour la dent artificielle, il est au moins important de tenir compte de la presence d'autres differences du potentiel de contact. Il est donc possible de monter une dent artificielle (21) sur un ancrage (9), qui tous deux sont solidarises au moyen de deux aimants permanents (19, 23).
