| 摘要 |
The present invention relates to an apparatus to register the movements of the lower jaw with reference to the skull, substantially comprising an adjustable upper registering yoke anchored to the bridge of the nose and the cheeks with a nasion profile roller for the record plates and the reference indicator on the one hand and the lower registering yoke which is attached by plastering through the intermediary of a spoon to the movable lower jaw on the other hand. The apparatus according to the invention is characterized in that the lower registering yoke exhibits on both side arms which are attached to the cross-bar, holes, into which a recording and measuring device is inserted which is in contact by its registering stylus in the previously determined hinge axis points of the lower jaw either against the left-hand or the right-hand record plate which are attached to the upper registering yoke and permits a continual registration of the movements in all three planes, i.e., a recording of the vertical and horizontal movements and simultaneously the measurement by mechanical, electronic, acoustic or optical means and/or the recording through an auxiliary instrument of the axial displacement of the horizontal movement. |
