For this purpose a plurality of successive bite movements or displacement movements of the lower jaw are recorded in form of electronic signal data and evaluated for the determination of the centric position.

Abstract: An electronic register device for recording movements of the lower jaw of a person relative to the upper jaw of the person, the device having a bite fork for recording a position of the upper jaw relative to reference points on the head of the person, wherein the bite fork is designed to receive a plastic compound for recording an impression of the dentition of the upper jaw. The register device further includes a lower-jaw attachment for recording movements of the lower jaw relative to the upper jaw. In addition, the register device has a reference body, wherein the register device is designed so that the reference body can be connected in a fixed position to the bite fork. The bite fork and the reference body connected thereto in a fixed position are designed in such a way that both the impression and also the reference body can be recorded by a scanning procedure. In this way, it is possible to establish a relationship between the scanned impression and the movement data recorded by the register device.

Abstract: A dental face-bow comprising a base part, two side arms that extend from the base part and two positioning elements, for example ear pieces for positioning the face-bow on the head of the patient. The positioning elements are situated on the side arms and can be displaced in relation to the side arms. The face-bow is also provided with a displacement device which is used to simultaneously displace the two positioning elements in relation to the side arms. To drive the positioning elements, a dial, which is situated on the base part, can be used for example to turn a flexible shaft that is rotatably mounted inside the two side arms. the two ends of the shaft are equipped with gears that co-operate with gear rods on the positioning elements. This arrangement permits the face-bow to be placed on a patient extremely gently, as there is in particular no relative displacement of the side arms.

Abstract: An auxiliary tool for an articulator having a lower part and an upper part which is connected with the lower part pivotally around a pivot axis extending transversely of the longitudinal plane of the articulator, there extending forwardly from the lower part a lower articulator arm and from the upper part an upper articulator arm, the auxiliary tool including a stand which is mountable on the inner side on the one articulator arm and has a head section on the side of which towards the other articulator arm there are arranged feeler elements for the sensing of certain surface parts on a jaw tooth model which is positioned on the other articulator arm. In order to increase the possibilities for use of the auxiliary tool, the head section has on its side towards the other articulator arm a positioning calotte.

Abstract: In a device (51) for holding an in particular plate-like implement (52) serving for forming teeth, in particular a positioning calotte, in an articulator (1), having a holder (55) for the implement (52) which is held on the articulator (1), upon employment of an articulator (1) with a detachable upper part (37) and upon employment of only the lower part (35) of the articulator (1) the holder (55) is mounted on the joint parts (36) of the lower part (35) pivotably about the pivot axis (5) containing the joint parts (36).

Abstract: In a training and practice apparatus (1) for simulating and practising clinical dental processes, with a model bust (6) which has a chest part, a neck (16) and a head (7) and is swivel-mounted on a carrier (4), the head (7) is mounted on a head carrier by means of a joint (17) and can thereby be swivelled into different working positions and fixed in the adopted swivel position, the joint (17) is arranged in the neck (16), the neck (16) has an engagement recess (28) opening approximately coaxially at its bottom end and the head carrier is a bearing rod, engaging in the engagement recess, on which the joint (17) is arranged and which is mounted in the chest part.
