INTRODUCTION: Prediction of the mesiodistal width of unerupted permanent canines and premolars is of major interest for orthodontic diagnosis and treatment planning.
METHODS: To improve the accuracy of the prediction, we looked for the best combination of independent variables with multiple linear regression.
RESULTS: The most accurate prediction was obtained for the combination of the mandibular right first molar and lateral incisor, and the maxillary left central incisor. Adding to the regression equation 1 erupted canine or premolar improved the accuracy of the prediction considerably. Because of the variable character of the eruption sequence during the second transitional period, a separate regression model for every canine or premolar was necessary. The precision of our new method and other methods from the literature was tested in a separate study group.
CONCLUSIONS: The results of this study show that our prediction method of the mesiodistal crown diameters of unerupted canines and premolars during the dental transition is accurate. A computer program was developed for user-friendly clinical application.
