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;
