Purpose:
To evaluate the influence of pretreatment radiographic features (angle, distance, and location) on the duration of active orthodontic traction.
Methods:
Sixty maxillary unilateral impacted canines were selected to analyze the panoramic features(angle, line spacing, and location) in pre-treatment patients, the results were evaluated using SPSS19.0 software package for multivariate regression analysis.
Results:
Pretreatment radiographic variables (angle, line spacing, and location) were significantly associated with the duration of orthodontic traction. The sex and site of impaction did not significantly affect the duration of traction.
Conclusions:
Impacted canine angle, distance and position can predict the orthodontic traction time.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
