Extractions provided space relief and coil springs and posterior bite turbos allowed the blocked-in lateral incisors to align. Intermaxillary elastics were effective in midline correction. 這是一個上顎雙側暴牙的案例，透過拔牙和自鎖式矯正器，達到良好的治療成果。拔除上下四顆小臼齒來創造牙齒移動空間，再利用後牙bite turbo和coil springs將blocked-in lateral incisors排齊，最後利用intermaxillary elastics來矯正中線。
