This paper presents a self-organized correction algorithm for the distorted measurements of the displacement pattern of the mandible recorded by the mandibular kinesiograph(MKG) based on the group method of data handling(GMDH) concept. A heuristic self-organization method aims to design the correction models characterized by the property that the corrected estimates of the mandibular measurements are the outputs of the nonlinear polynomial functions the input of which are the measurements correspondonding to the neighbouring nominal coordinates. The proposed method for building a correction algorithm was applied to the distorted trajectories of the measurements determined for the simulated mandibular incisor-point displacement performed on the stereotaxic device. The GMDH modeling yielded a mean estimation error for 45 coordinate variables of 0.27 mm. with a standard deviation of ± 0.31mm., thus suggesting a possible application of this method to the signal correction of the MKG.
