Tracing device and method for recording mandibular movement

摘要

A tracing device for mandibular movement comprises mainly an upper jaw plate, a lower jaw plate and a coupling device, and the device is able to be mounted in the oral cavity of a patient regardless of whatever the patient is dentulous or edentulous. A recording method therewith can be carried out without elevation of the occlusal vertical dimension of a patient. An accurate recordiing of the jaw relation is taken by recording on the device an occlusal vertical dimension and an incisal guide angle which are settled in a prosthesis, and recording the mandibular position three dimensionally. Another feature of the device is to enable the reproduction of the record on the articulator. By recording the mandibular position and the mandibular movement with the device, the occlusal reconstruction based on the full mouth rehabilitation which has been regarded conventionally a most difficult prothesis method is carried out accurately.
