Prediction of Impacted Maxillary Canine Eruption using Warford Method

Impaction most commonly involves lower third molars, followed by permanent upper canines. Warford et al11 used a bi-condylar line as a horizontal reference line to predict the maxillary canine impaction in mixed dentition. The measurement was taken of the mesial angle formed by using the constructed horizontal and the long axis of the maxillary canine. In this study, a modified Warford method was used for young adults and results after orthodontic treatments were discussed. 4 patients with impacted canines were examined using the Warford method. When evaluating the impacted canine cases, the modified Warford method must be applied carefully and local conditions, like root anatomy, should also be evaluated.
