Definitions

  • Dental prosthesis supports of the implantable kind generally consist of metalic pins sunk into the jawbone. The pressure exerted on the bone by these rigid elements brings about a local lysis of the bone tissue which does not allow the desired adherence.
  • an implantable support for dental prosthesis comprising an implantable body portion, an elastomer envelope at least partly enclosing said body portion, and an outer surface to said envelope colonizable by living tissue.
  • Such a support does not cause bone lysis and permits efficient securing by colonization and interpenetration.
  • a further advantage of the invention is that the support can take up a well defined position but is sufficiently resilient to deaden and distribute the forces to which it is subjected.
  • the support can be implanted into the jawbone. after drilling the latter; it can also be postioned in the socket after extraction of a tooth.
  • its external configuration may vary in accordance with the manner of use.
  • the support is, of course, necessary to maintain the support in suitable position until it has consolidated, for example by means of a fixing device of conventional kind which has been prepared and adjusted beforehand.
  • the evelope may also br wholly implanted and enclosed by gingival suture during the colonization period (3 to 5 weeks). This last technique is'particuarly suitable for simple or split pins.
  • the colonizable envelope contains a simple filling, e.g., a filament of nylon, fluorinated resin or polyolefin which slides with gentle friction in the jacket. After colonization of the jacket the filling is withdrawn and the final support is forcibly inserted.
  • the prosthesis is provided with a soft and resilient base enabling the pressure of chewing on the gum to be absorbed, the weak movements transmitted to the support being in turn absorbed by the resilient envelope.
  • the pin or grid forming the body portion may be of platinum, tatalum, stainless steel or other material employed in the dental art;
  • the envelope may be of an elastomer (preferably silicone), its surface may-be rendered colonizable by adhesively affixing a textile sheath such as a tubular tricot or a velvet of polyester fibre (polyglycol terephthalate).
  • FIG. 1 is a schematic cross-sectional elevation of one embodiment of implantable support according to the invention, shown positioned in a jawbone;
  • FIG. 2 is a transverse section through the support of FIG. 1.
  • the construction illustrated in the drawing includes an implantable-body portion in the form of a stainless steel pin 1, which, for example, may be 1.5 mm in diameter.
  • An elastomer enveloper 2 partly encloses the pin and is itself surround by a glued textile sleeve 3 of crimped polyester velvet.
  • the envelope 2 is closed by a base or stopper 4, the envelope and stopper being formed of silicone elastomer, with the stopper being vulcanised in place.
  • the gum of the patient is indicated by the reference numeral 5.
  • a dental endosseous root implant having a tube able to receive an artificial tooth/supporting pin, said tube being provided with an external surface colonisable by surrounding tissues, the improvement comprising forming said implant as a tubular member closed at one end and formed of a resilient elastomer the external surface of which is covered by a textile sleeve.
