Embodiment Construction

[0055] In a very schematic illustration, Figure 1a and Figure 1b The maxilla OK is shown separately in top view ( Figure 1a ) or Mandible UK ( Figure 1b ). For each of the jaws, sixteen teeth are drawn, with maxilla OK teeth starting from incisors with O1 and O2, via premolars O4 and O5, via molars to wisdom teeth with O8 numbered consecutively. In the same way, the teeth of the mandible UK are numbered consecutively from the incisor with U1 through the molar to the wisdom tooth U8.

[0056] Sensor OS1 is arranged on the upper jaw OK. Optionally, other sensors can also be provided. The maxillary sensor OS1 is fastened at one or both of the premolars O4 and / or O5. In a similar manner, the mandible sensor US1 is arranged on the mandible UK. The mandibular sensor US1 is arranged on the premolars U4 and / or U5. Optionally, further sensors can be provided on the maxilla and / or mandible.

[0057] As can be inferred from the top view, sensor OS1 or US1 is arranged directly...

Abstract

The invention relates to a device (1) for measuring a relative position and/or movement of a mandible (UK) relative to a maxilla of a patient, comprising an emitting coil (8) for emitting an electromagnetic measuring field (5), at least one mandible sensor (US1), said mandible sensor (US1) being placed and/or can be placed on teeth in the mouth (U1-U8) or in the mouth on a mandible device (UK). The mandible sensor (US1) is designed as a sensor at least for determining a position in a measuring field (5) and/or relative to the emitting coil (8), also comprising an evaluation device (3) for determining the relative position and/or relative movement of the mandible (UK) relative to the maxilla (OK) based on positions determined by the sensor (US1). The sensor coil (8) is placed and/or can beplaced outside of the mouth on the side or above the maxilla (OK). The invention also relates to a method for determining a relative position and/or movement of the mandible (UK) relative to a maxilla(OK) of a patient with a device (1), a device (X) for simulating and transferring a measured relative movement from the method and a holding device for at least one maxilla sensor (OS1) and/or at least one mandible sensor (US1).

Description

technical field [0001] The invention relates to a device for measuring the relative position and / or relative movement of a patient's mandible relative to the maxilla. The device has a transmitter coil for emitting an electromagnetic measuring field and at least one sensor, the sensor being connected at least to the mandible. Furthermore, the device comprises an evaluation device which determines a relative position and / or a relative movement of the mandible relative to the maxilla on the basis of the sensor signal. The invention also relates to a corresponding method using the device as well as a device for simulating and transmitting the measured relative movement resulting from the method and a holding device for at least one maxillary sensor and / or at least one mandibular sensor . [0002] In dental technology, digital or physical impressions of the patient's mandible and maxilla are required for various purposes. A typical way of making a solid impression is, for exampl...
