3D printed occlusal & condylian guide


The technology addresses two major threats of orthognathic surgery that is heavy both in its operative continuations and its possible complications:

  • Restoration of functional equilibrium of the manducatory system;
  • Optimisation of the dental occlusion at the end of the medical procedure.

It can be used for both functional & aesthetic purposes.

Fully based on 3D approach, the technology implements a four steps method from virtual planning of an orthognathic mandibular osteotomy to the production of a simple and reliable device to conduct surgery, including:

  • Acquisition and surface extraction;
  • Virtual planning;
  • Modelling & printing;
  • OCPD evaluation.


Usually carried out from plaster models, the planning and production of surgical occlusal guides suffer from imprecision that may cause temporomandibular functional disorders, in response the technology offers :

  • Non invasive approach optimising the surgery duration;
  • No more need of classical CPD (Condylar Positioning Device);
  • 3D personalised fitting design;
  • Anatomic locking clips onto the bones;
