Three-dimensional registration of real jaw motion tracking data and its therapeutic consequences

When determined by conventional jaw relation recording methods, the real position of the condyle remains largely unclear because the geometric relationship between the reference point and the position of the condyle is unknown. Sicat Function combines cone beam computed tomography (CBCT) data with digital jaw motion tracking (JMT) data and digital intraoral surface data. It is thus capable of measuring and visualizing patient-specific jaw movements. The corresponding patient-specific treatment position can be defined and integrated in various therapeutic appliances, eg, repositioning splints designed to increase the vertical dimension of occlusion (VDO).
