This gives the possibility to subsequently differentiate root canals, but requires more than one image
[0005] However, none of the above methods describe reliable positioning of sensors and imaging devices to ensure non-overlapping imaging of all root canals without necessarily producing an undesired number of images

Embodiment Construction
[0051] According to the first embodiment of the present invention, figure 1 A sensor holder ( 1 ) according to the invention is shown having a snapping device ( 2 ) on which a holding device ( 3 ) for a sensor (not shown) is arranged. After insertion of the corresponding sensor into the holding device (3), the part of the sensor holder (1) is inserted into the patient's mouth, wherein the patient holds the sensor holder (1) by biting on the occlusal device (2). in the proper location. In this case, the positioning of the holding device (3) and the centering device (4) can be adjusted before insertion into the oral cavity or even after the sensor holder (1) is positioned in the patient's mouth and held by the patient. on the basis of figure 1 In the embodiment of The ball joint can be set to the desired position data. To this end, the ball joint 6 comprises at least an operatively connected actuator (not shown), wherein data is received from a radio receiver, not shown, for...

The invention relates to a computer-implemented method for determining an optimal 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 non-overlapping imaging of at least two tooth root canals. The invention also relates to a sensor holder (1) for intraoral imaging, comprising at least one bite device (2) insertable into the oral cavity of a patient, at least one holding device (3) at least indirectly engaging with the bite device (2) for securing 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 operatively connected to the bite device (2) by means of at least one centering device holding portion (5), characterized in that the centering device holding portion (5) is designed such that the positioning of the holding device (3) relative to the centering device (4) is continuously variable in angle and / or distance, and to a method for optimizing and performing intraoral imaging.
Description
technical field [0001] The present invention relates to a sensor holder for intraoral imaging, its use in intraoral imaging methods, a method for determining optimal positioning in intraoral imaging, and a method for producing such imaging method. Background technique [0002] After endodontic treatment, an intraoral control scan is usually performed to verify that all root canals have been successfully treated. To do this, each root canal must be captured without overlapping other root canals. However, due to anatomical conditions, it is often difficult to align imaging devices and sensors (eg, detectors such as film or fluorescent plates) at the correct angle so that all root canals are imaged without overlapping and with a single image. [0003] Usually, one tries to avoid the problem of overlapping root canals by means of so-called eccentric X-rays to estimate the angle. Alternatively, multiple images can be taken from different angles in order to capture each root ca...
