Purpose: The purpose of this study was to evaluate the possible factors that affected the duration of forced eruption of impacted upper incisors. Methods: 24 patients (mean age eight years and nine months old ), 25 upper impacted incisors were included in this study. Factors analysed included the age, the distance from impacted incisor edge to the occlusal plane, presence of odontoma or supernumerary tooth, the crown orientation,eruption space loss and root dilaceration. Standardized panoramic radiograph was used as measurement tool.Results: The treatment duration is positively correlated to the distance from the incisor ledge to the occlusal plane (R2 =0.21; p=0.02) . No significant correlation was found between the treatment duration and age.The presence of the other variables increased the treatment duration, however, the results are not statistically significant. Conclusion: The distance from impacted incisor edge to the occlusal plane can be used as an estimate of time needed to complete the forced eruption technique.
