Definitions

  • the bone tissue of the jaw grows into or onto the surface of the implant (so-called osseointegration).
  • the implant should normally remain in the jaw.

  • the object of the invention is to avoid these disadvantages or at least to reduce them.
  • a method preceding the removal of the implant and a corresponding device are to be specified, with which a downstream mechanical removal of the implant can be simplified.
  • This energy source can be coupled with the implant to heat it either mechanically or by other interaction.
  • the energy source may be a sound source, in particular a high or high frequency sound source, in particular an ultrasound source, a heat source, in particular an electric heat source, in particular resistance heating, and / or a heat radiation source, an induction source or a radiation source for electromagnetic radiation, in particular light or Infrared, in particular a laser act. Any combination of these enumerated energy sources can also be used.
  • Advantages and advantageous effects of the device according to the second aspect are particularly evident from the comments on the first aspect of the invention (method).
  • at least the implant is heated at least at its boundary surface or boundary layer to the tissue to at least a predetermined destruction temperature.
  • the targeted incorporation of suitable materials into the implant makes it possible to achieve respectively targeted and, in particular, locally specific, necrosis.
  • the energy is coupled into the implant and distributed in such a way that at least the sites relevant for the detachment of the implant are necrosed, or the corresponding connections are released.
  • the implant is heated by Joule heat, which results from eddy currents and / or magnetic reversals produced by alternating electrical and magnetic fields.
  • induction heating can be used for materials with pronounced ferromagnetic properties.
  • inductive heating is also considered for materials with less pronounced or even missing ferromagnetic properties.
  • eddy currents which are converted into Joule heat in the material, are induced by time-varying magnetic fields as they occur during induction. With suitably selected magnetic fields, it is thus possible, the implant material purely on To heat eddy current losses to the desired destruction temperature. This is all the more so as in biological tissue comparatively low destruction temperatures, eg. B. in the range of 50 ° C, can already lead to success.
