In this skeletal CIII case, first extract L8s to create spaces and applied BS screws, posterior bite turbos and CIII elastics to raise the bite and retract the mandibular dentition. Then use anterior bite turbos and early light short elastics to correct anterior crossbite.
這個骨性 CIII的案例中，首先利用拔牙來增加空間，再透過BS screws，後牙區bite turbos和CIII elastics打開咬合並將下排收進來。再來利用前牙區bite turbos和橡皮筋改善前牙錯咬。
