REGRESSION METHOD FOR MODELING WIDTHS OF TEETH

摘要

The present invention relates to a regression method for modeling the width of teeth, for use in the absence of pre-extraction records, particularly for rehabilitating edentulous patients or subjects. The method establishes relationships between the widths of the maxillary anterior teeth and certain facial dimensions, with high correlation coefficient. The facial dimensions used are the interpupillary distance (150) and the interalar width (140). The regression method of modeling includes elimination of outliers and correcting non-constant variance by a weighted least square method, from the measured variables used for the regression method.
