Abstract
A facebow for use in measuring the positions of the temporomandibular joints of a patient relative to the maxillary teeth of the patient so that such positions may be transferred to an articulator may be constructed so as to utilize two normally spaced side arms which are connected by a mechanical structure permitting the arms to be moved linearly toward and away from one another. A mechanical structure is provided for accomplishing such movement in such a manner that when either of the arms is moved the other arm is concurrently moved in a corresponding manner. The connecting structure carries a frame including a bite fork or equivalent adapted to be positioned in the mouth of a patient along or adjacent to the maxillary teeth in making an impression of these teeth. The frame carrying the bite fork is capable of being adjusted relative to the connecting structure and thus relative to the arms.
