[Dynamic correction of occlusal surfaces by means of the CAD-CAM methods. II].
A method of computer aided dynamic correction of digitised occlusal surfaces has been described. A mathematically simulated fully adjustable software articulator has been designed and used in place of a mechanical dental articulator. An optical impression of plaster models is performed using a laser scan device. The digitised models are oriented automatically to each other and to the coordinate-system of the software articulator. A correction algorythmus is supervising the two occlusal surfaces during basic articulator movements and correcting them at places of interference according to a pre-set scheme. An electronic face-boe is being constructed to enhance the preciseness of the model orientation. After completion the method can be used as an integrated part of a foreign dental CAD/CAM system to dynamize static occlusal surfaces, or as a separate system for computer aided functional analysis and correction of natural and artificial occlusal surfaces.
