3D printed occlusal & condylian guide

DESCRIPTION

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.

APPLICATIONS

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.

BENEFITS

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;
