Abstract
A method for determining the optimum relative position of at least one sensor and/or at least one imaging source of an imaging device for at least one intraoral imaging, and for the non-overlapping imaging of at least two tooth root canals. The disclosure also relates to a sensor holder (1) for intraoral imaging including at least one biting device (2) that is insertable into the mouth of a patient, at least one holding device (3) at least indirectly engaged with the biting device (2) for fixing at least one sensor, and at least one centering device (4) for aligning at least one imaging device. The centering device (4) is at least indirectly in operative connection with the biting device (2) via at least one centering device holding portion (5).
Claims19
A computer-implemented method for determining the optimum relative position of at least one sensor and/Or at leaSt one imaging source of an imaging device for at least one intraoral imaging, and for the non-overlapping imaging of at least two tooth root canals, the method comprises:
- a) evaluating at least one digital image of a patient;
- and
- b) computing an optimum position of the sensor and the imaging source based on the evaluation mentioned under a),
- wherein the evaluating comprises an evaluation of a digital recording, namely a volumetric tomography (DVT) imaging, which comprises the simulation of a projection of at least one virtual sensor and/or at least one virtual imaging source from at least two different angles and/or positions for the imaging, or DVT imaging of the intraoral anatomy of the patient,
- wherein, the simulation is carried out several times;
- and wherein an optimum angle and/or the optimum position is computed so that overlapping of the root canals is minimized, and largely avoided.

The sensor holder according to claim 14, further comprising:
- at least one triggering prevention facility for the imaging device, and/or
- at least one display unit, which indicates when the positioning of the holding device relative to the centering means is not optimally adjusted,
- wherein, the display unit is so designed that instructions for a correct, manual positioning, are displayed.
The sensor holder according to claim 14, wherein irradiation by the imaging device is directed to an active and/or sensitive region of the sensor, wherein radiation of the imaging device is at least partially stopped or attenuated by the centering means.
A sensor holder comprising
- at least one biting device insertable into the mouth of a patient,
- at least one holding device, which is at least indirectly operatively connected with the biting device, for fixing at least one sensor, and
- at least one centering means for aligning at least one imaging device, wherein the centering means is at least indirectly operatively connected with the biting device via at least one centering means holding portion,
- wherein the centering means holding portion is designed such that positioning of the holding device relative to the centering means with respect to angle and/or distance is continuously variable.
