Class II with Deep Bite |【Chris Chang Ortho】CC862

This case presents a low-angle Class II deep bite patient with retroclined lower incisors. The treatment was completed without extractions, using bite turbos to open the deep bite and Class II elastics to correct the overjet. Open-coil springs were applied to establish a favorable arch form within seven months. With the precise torque control of the Damon Ultima system, significant improvement has already been achieved by month 25. 這是一個low angle合併下前牙retroclination的Class II deep bite案例。治療採用不拔牙方式，運用Bite Turbo打開Deep bite，以及Class II elastic改善overjet。特別的是，光使用open coil spring在7個月就獲得很好的牙弓曲線，加上Damon Ultima對於torque精準的控制能力，在第25個月就已經有顯著改善。
