Abstract
Title: Efficiency of Molar Distalization with the XBow Appliance Related to Second Molar Eruption Stage. Objectives: To make a quantitative evaluation on lateral cephalograms of horizontal, vertical and angular changes in the position of the maxillary first molar when it is distalized with the XBow appliance. Specifically, these changes will be evaluated and compared in the presence and absence of erupted maxillary second molars to determine if there is an optimal time to treat. Methods: Lateral cephalograms were retrospectively obtained at the start and after completion of all active treatment with the XBow appliance. In one group of patients distal movement of the maxillary first molars was performed before the eruption of maxillary second molars; in the other group of patients both first and second maxillary molars were simultaneously moved distally. All cephalograms were superimposed on palatal plane using the method of best-fit. Changes in the position of the maxillary first molar were measured as differences between specific landmarks before and after treatment. Results: A MANOVA revealed that the eruption stage of the maxillary second molar did not have a significant effect on the change in position of the maxillary first molar after treatment with a XBow appliance. Conclusion: When using the XBow appliance in the late-mixed to early-permanent stage of dentition, distalization of the maxillary first molar is likely no more effective before the eruption of the maxillary second molar.
