Abstract:
In patients with unstable mandibular movements who are accompanied by involuntary facial muscle movements and asymmetrical changes in the facial features, many difficulties exist in determining the vertical dimension of occlusion, recording centric relation, and transferring information about the occlusal plane. In this case, for a patient with unilateral facial nerve palsy who was edentulous for a long period of time, a CAD-CAM provisional prosthesis was fabricated using a 3D printing customized gothic arch tracer and a prefabricated occlusal plane recorder, the POP bow system, to achieve a stable interarch relationship. Afterwards, a full mouth implant fixed prosthesis was fabricated by delivering an appropriate vertical dimension of occlusion, a reproducible centric relation, and a correct three-dimensional occlusal plane, and continuous maintenance was performed to restore functional and aesthetic oral health to the patient.
