Abstract: | Objective: To evaluate the treatment result of unilateral posterior scissors bite, and to go further into the methods for orthodontic treatment. Methods: 11 patients (4 males and 7 females, aged 13 -26y) with unilateral posterior scissors bite were treated with straight wire appliance. Anterior flat plane or posterior bite plane, as well as the reciprocal elastics were used during the treatment. Pre - treatment and post - treatment eephalometric radiographs were taken and analysed. Results: After treatment, the scissors bite were corrected. Normal anterior overjet and overbite and ideal occlusal relationships were obtained. Lower third facial height increased. Conclusion: Unilateral posterior scissors bite could be effectively corrected by straight wire appliance and proper reciprocal elastics. |
