Abstract
A device for recording an image in the oral cavity has a sensor with a housing having two main surfaces. The sensor includes an image recording layer positioned in the housing parallel and adjacent to one of the two main surfaces. A signal line is connected to the housing at one of the two main surfaces remote from the image recording layer. The signal line transmits signals of the image recording layer to a separate image processing and memory unit. A holder with a bite section and a receiving channel in which the sensor is received is provided. The holder has an abutment surface extending parallel to the two main surfaces. The abutment surface has guide means for aligning the holder and the sensor relative to one another. A hose is slipped over abutment surface and sensor for fastening the sensor at the holder.
