Abstract :

The purpose of this cephalometric study was to compare the maxillary incisor inclination and position after completion of the orthodontic treatment treated with lingual and labial fixed orthodontic appliance. Post–treatment lateral cephalometric radiographs were traced using standard acetate mate paper. Landmarks were marked and measured the incisor inclination and position using parameters of Steiner analysis, UI–NA0 and UI–NAmm. The final positions of maxillary incisors achieved after using both the systems were assessed and compared. Results: Lingual appliance torqued the maxillary incisors to normal positions in non–extraction cases as compared with labial appliance. But, lingual appliance uprighted the maxillary incisors after retraction in extraction cases as compared to labial appliance. Conclusion: Lingual appliance has better torque control and positioning of maxillary incisors than labial appliance in non–extraction cases. And with increasing the torque values , we can expect better torque control and positioning of maxillary incisors in extraction.
