Abstract: The invention relates to a device which allows to preferably explain and demonstrate three-dimensional objects, such as anatomic models or also models and exhibits for museums and fairs. According to the invention the model 1 is fastened to the adjacencies by at least one multiple-component force-torque measurement device 2, includes an electronic storage and evaluation unit and an optic-visual and/or acoustic indicating device. The force-torque measurement device 2 converts the forces and moments arising when the model 1 is touched into electrical measurement signals to be leaded to the electronic storage and evaluation unit, and in the electronic storage and evaluation unit the contact zone is calculated from the forces and torques detected as a result of the touch, and is communicated to the operator as a signal by means of the optic-visual and/or acoustic indicating device.

Abstract: The invention relates to a method and device for learning and training dental treatment techniques, according to which a force is applied to a tooth (2) preferably by means of tools (4) in order to examine or treat this tooth. A mandible (1) or the tooth (2) is coupled to a force measuring device (3) in a manner that enables the forces applied to the tooth (2) to be represented in the form of electric measurement signals (5) that are fed to a data processing device (6). Said data processing device has a data memory (7) in which a multitude of reference force/time courses of different force/time-determined tooth treatment steps can be stored in a manner that enables them to be retrieved, whereby the forces applied to the tooth (2) and their temporal course are compared with a reference force/time course.

Abstract: The invention relates to an implant layer positioning system comprising a device that can be fixed to a bone section and is used to plan the positioning of implants in order to enable corrective operations to be performed on the bone with optimum bone contact. Said device reproduces the geometry of at least one section of the implant and can be freely oriented by the operator towards accessible parts of the bone. The inventive system also comprises a control unit which virtually evaluates the relevant implant parts, on the basis of the navigation data of the tracked device and the data input of the planned corrective operation, in the form of three-dimensional geometry bodies in fluoroscopy sketches or other referenced image or geometry data.
