Abstract

Jaw motion tracking, which is introduced in recent case reports, is a method which records the patient’s individualized pathway of the mandibular movements along with facebow transfer, and reproduces the information in the virtual space of computer-aided-design/computer-aided-manufacturing (CAD-CAM) software. In this present case, a collapse of the occlusal plane was observed, due the loss of posterior teeth for a long period. Full-mouth rehabilitation with an increase in the occlusal vertical dimension was planned. First, the patient’s mandibular movements were recorded on the newly established jaw relation by jaw tracking, and this information was assembled with the patient’s intraoral data to create a virtual patient. Implant planning and diagnostic wax-up was done on the virtual patient, leading the fabrication of the provisional prosthesis. On the newly established jaw relation with an increase in the occlusal vertical dimension, canine guidance of the provisional prosthesis was checked. Finally, the provisional prosthesis was carried out to the definitive prosthesis. Using the advantages of the technologies in the digital dentistry, the patient was satisfied with the function and the esthetics after the treatment.
