Whole arch distalization has been tried by using headgears, pendulum appliances, and removable appliances in the literature, above methods either count on patient's cooperation or too complicate and the amount of distalization usually is limited. On the lower arch due to dense cortical bone around the lower molar region, distalization of the whole arch almost impossible. The author found out that using the mini-screw only, most of the whole arch distalization movement could be done. The author is going to present different clinical cases including Class II and Class III treated with whole arch distalization by using mini-screws only. 2D cephalometrics, panorex, and 3D cone beam CT will used to illustrate the details.
