This technology is based on functional analysis of TMJ and an innovative concept which makes it possible to prepare the implant more systematically.

Its ergonomic design and the highly-simplified connection of the implant to the bone considerably reduce side-effects and restore natural mobility. The trauma associated with surgery is considerably reduced, leading to a significant reduction in the cost to society of treating this pathology.


This innovative system offers many advantages :

  • Direct integration into the lower jaw,
  • Natural distribution of the forces exerted on the lower jaw,
  • Less stress on the bony tissues,
  • Restoration of natural mobility,
  • Easier to implant, thus reducing operating time.

The key innovation of this prosthesis is that it establishes an intraosseous connection, thus ensuring a physiological transmission of actions, respect for natural movement, and a reduction in the need for resection.
