In oral rehabilitation, the integration into the digital flow of mandibular movements and the patient's individual reference planes optimizes the functional adaptation of prosthetic elements whose design is computer aided. The innovative Modjaw® device allows you to record and then virtually simulate mandibular movements.

This retrospective study aims to: 1) Test the reliability of the Modjaw® device; 2) Measure the condylar displacements of asymptomatic subjects for the arbitrary programming of simulators.

Kinematic recordings of 22 healthy volunteers (15F / 7H; mean age: 22.2 years) were analyzed. Two recording sessions were carried out within one month of each other, by three different operators; each subject was followed by the same operator during the first (E1) and the second (E2) recording. The values of sagittal condylar inclination (SCI) obtained in opening, protrusion, right-left mediotrusion were calculated at 3 and 5 mm of condylar displacement. The transverse condylar inclination (TCI) was calculated at 4mm.
