Method and apparatus for 3 - dimensional movement analysis of tooth surfaces of the upper jaw in relation to the lower jaw

摘要

A method for 3 - dimensional movement analysis of tooth surfaces of the upper jaw (ok) in relation to the lower jaw (uk) with a measuring system for the determination of all degrees of freedom of movement of two solid body by means of electronic measuring sensors, in which for this purpose a measuring sensor is rigidly with respect to the ok and a measuring sensor is mounted rigidly with respect to the uk and the positions of the measuring sensors continuously during the execution of uk - movements are recorded, characterized in that, in relation of the ok - sensor at least three ok - relative to points are determined, the directly on the tooth surfaces of the ok - teeth or which are located on or to a device, which is connected with the ok - teeth, or by a fixed geometry for ok - sensor and the ok - teeth that in relation of the uk - sensor at least three uk - relative to points are determined, the directly on the tooth surfaces of the uk - teeth or which are located on or to a device with the uk - teeth is connected, or by a fixed geometry to the uk - sensor and the uk - teeth are distinguished,..
