Abstract: A method for producing a computer-aided virtual articulator for dentistry includes recording and collating body-related data from a plurality of persons to provide a data collection, generating a model of a masticatory apparatus from the data collection via statistical methods, and using the model to supplement body-related data recorded from a single patient to provide a simulated individual movement model of the masticatory apparatus of the single patient and to simulate a movement of the masticatory apparatus.

Abstract: Process for manufacturing a treatment template, in particular a drilling template 7, which is used for pinpoint guidance of an instrument in the oral cavity of a patient, whereby the treatment template is secured in a detachable manner during an operative intervention in the jaw area of the patient in defined position, whereby in the jaw area, a holder is anchored especially by implantation for detachable fastening of the treatment template 7, whereby the holder has marker structures 1a that put up a three-dimensional coordinate system and that can be shown by an imaging process together with the anatomy of the patient, whereby a set of three-dimensional image data of the jaw area 2 that is equipped with a holder is recorded, in that based on the image data, the planning of the implants and the planning of the treatment template 7 that is to be secured in a defined manner to the holder is done, whereby the plans relate to the coordinate system that is put up by the marker structures 1a.

Abstract: Disclosed is a method for pictorially representing and determining tissue densities of a body region, especially in the mouth/jaw/face region (1), of a patient. According to said method, a set of three-dimensional image data representing the body region as well as calibration data that is provided as three-dimensional image data and represents a calibration phantom (5, 8, 15) having a previously known density are photographed by generating an image while the tissue densities are derived from a comparison of the calibration data with the image data. The image data and the calibration data are photographed in the framework of the same shot and in an upright position of the patient, particularly during sitting or standing. The calibration phantom (5, 8, 15) is held in the immediate vicinity of the body region (1) that is to be photographed during the shot by means of a fixture (4, 10, 14) which is fixed independently of the patient's body and in a defined relation to the imaging device.
