This retrospective clinical study was aimed at evaluating the nature of maxillary first molar movement after distalization with the distal jet and its effects on incisor position and facial soft-tissues. Materials and Methods The study sample consisted of 22 subjects (10 boys, 12 girls) having an average age of 13.04 years at the time of obtaining pre-treatment diagnostic records. The distal jet was the only appliance used during the distalization phase of treatment. All patients were treated by a single clinician with strict adherence to a standardized treatment protocol. The average duration of molar distalization was 6.09 months. Pre-treatment and postdistalization lateral cephalograms were obtained to analyze dentoalveolar and soft-tissue changes. Results This study revealed that the maxillary first molars were distalized by an average of 4.29 mm into a class I molar relationship. In the process, the molars exhibited distal molar tipping (6.66°) and extrusion (1.45 mm). The maxillary incisors were displaced and tipped labially by 1.89 mm and 2.84° respectively, leading to an increase in overjet by 0.86 mm and decrease in overbite by 0.98 mm. The soft-tissue changes involved upper and lower lip protrusion by 0.84 mm and 1.45 mm respectively, with an increase in lower facial height by 1.36 mm. Conclusion This study confirmed the reliable and effective distalization of maxillary first molars with the distal jet, with certain undesirable and reciprocal effects on incisor position and minimal impact on the facial soft-tissues.
