Abstract
Abstract In place of the conventional axis-orbital plane recording bow normally attached to a mandibular movement recorder to determine a patient''s axis-orbital plane for transfer to a dental articulator, indents are made of the patient''s teeth in reference plates during the recording operation. These indents or impressions are formed in reference plates which are substituted for the conventional clutches normally used to attach and support the recording bows during a recording operation. By then simply transferring the hardened indents or impressions to already available plaster casts of the patient''s teeth, previously mounted on the articulator, the correct axis-orbital plane is automatically established.

Claim 1
Independent Claim
168 words
A method of transferring axis-orbital plane information with a dental mandibular movement recorder to a dental articulator wherein plaster casts of a patient''s Lower and upper teeth have been made and are mounted on the articulator with an axis orbital transferring device and centric relation recording, comprising the steps of: a. providing lower and upper reference plates coupled to the recorder in place of the usual clutches; b. lining the reference plates with impression taking material; c. inserting the reference plates in the patient''s mouth holding his mandible in a centric position; d. adjusting the various recording stylii and recording surfaces of the recorder; e. holding the adjustment until the impression material has hardened; f. making the various recording traces by the recorder; and, g. transferring the hardened indents in the reference plates to the casts on the articulator so that the recorder is positioned on the articulator with correct axis-orbital plane relationship automatically established as a consequence of the casts fitting properly in the hardened impression material.
