Electronic register device for recording jaw movements

Electronic register device for recording movements of the lower jaw of a person relative to the upper jaw of the person, the register device comprising:

• a bite fork adapted to record a position of the upper jaw relative to at least one reference point on the head of the person, wherein the bite fork is further adapted to record an impression of the dentition of the upper jaw,
• a lower-jaw attachment for recording movements of the lower jaw relative to the upper jaw;
• and
• a reference body,
• wherein the reference body is adapted to be connected in a fixed position to the bite fork, wherein the bite fork and the reference body connected to it in a fixed position are designed such that both the impression and the reference body are arranged to be recorded by a scanning procedure, the reference body including at least one scan element that protrudes from the reference body.

• a lower-jaw attachment adapted to record movements of the lower jaw relative to the upper jaw,
• wherein the bite fork has a first reference body connected in a fixed position to the rest of the bite fork, and the lower-jaw attachment has a second reference body connected in a fixed position to the rest of the lower-jaw attachment, wherein the bite fork is designed in such a way that both the impression and also the first reference body can be recorded by a scanning procedure,
• wherein one of the first reference body and the second reference body includes at least one scan element that protrudes from the at least one of the first reference body and the second reference body.
