Abstract: The jaw of a person and a model thereof is represented with a series of steps. A device for positional determination, which has marking points, is inserted into the oral cavity of the person, at least one picture of the jaw of the person is taken with an imaging process, such as X-ray, CT, MRI or the like, including the marking points in the picture. The picture is stored as a data set and the marking points are identified. After an impression is taken of the jaw, a model is created. The representation itself includes the following steps: a further 3D sensor is brought to the model of the jaw. Next, the device for positional determination is reinserted into the model of the jaw in the same position as when the picture was taken. The positional relationship is determined between a 3D sensor on the device and the 3D sensor on the model of the jaw. After the device has been removed, a further 3D sensor is brought to the model of the jaw and inserted in the same position as when the picture was taken.

Abstract: A system and method including a transparent display positioned between an object and an observer on which displays a superimposed data image transformed from structural data by calculating the parameters of a three dimensional matrix with information collected from position sensors. The mathematical parameters of the three dimensional matrix are defined in order to transform the structural image data into the perspective display data. Once the parameters of the three dimensional matrix are established, any points of the structural image can be shown on the display as a virtual image corresponding to the points on the object in real time.

Abstract: The invention relates to a method for displaying moveable bodies, in which an optical representation of the body and a data field attributed to this body are displayed simultaneously or alternately from the same perspective and on the same scale in real time. The method includes the following steps:providing the optical image-reproduction system comprising a camera and a monitor;allocating a 3D - data field to the body having a certain position;continuously recording of the 3D - position of the body;continuously calculating of a display of the data field equivalent to the body's momentary position;simultaneously or alternately representing the optical image and the data field on the monitor.An apparatus for carrying out this method is also provided.
