Gnathologic instrumentation engraved recordings Dental Equipment Dental Occlusion Jaw Relation Record This film demonstrates two methods for dentists of recording a patient’s jaw movements and reproducing them on an anatomic articulator. Gnathology deals with the correlation between the occlusal surfaces of the teeth and the pattern of jaw movement as dictated by the temporal mandibular joints and incisal guidance. Normally, jaw movement should occur without interference from collisions between opposing teeth. Such interference can cause trauma to the temporal mandibular joint and lead to temporal mandibular pain dysfunction. For diagnostic and corrective procedures, the pattern of jaw movement must be recorded using an articulator. Two ways of doing this, the pantographic technique and the engraving technique, are performed separately and their results compared. Credits: Merrill C. Mensor, Jr. and Ronald H. Roth.
