Abstract: The invention refers to a method, to a computer program and to a data processing machine for the preparatory work of dental treatment. This invention in particular considers technical parameters concerning the order of the individual treatment steps. For one embodiment, it is intended to issue parts of the treatment sequence plan and to input data via handwriting.

Abstract: An intraoral sensing device for producing tooth and jaw images of a patient has a housing with a back. The housing has an interior. An image sensor is positioned in the interior of the housing. A printed circuit board with electrical contacts is positioned in the interior of the housing and connected to the image sensor. An electric cable, for connecting the sensing device to an image processing unit, is provided. It extend into the interior of the housing at a location of entry and has electrical leads. The electrical leads are connected to the electrical contacts of the printed circuit board. The electric cable extends from the location of entry at the housing at an angle of 0.degree. to 10.degree. relative to the back.

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.

Abstract: The invention relates to a process and an apparatus for spreading a moving web of textile material during a treatment by means of fluid streams directed from the middle to the edges of the web. The side edges of the web are probed by sensors which control the fluid streams directed onto the associated edges of the web. In this way, reliable spreading is obtained with minimal outlay, even with different webs of textile material and under varying working conditions.
