Comments

In order to move the molars far away, we used the classic method of class II and classification: the lip tilted to the front teeth, then lowered, and then retracted. In addition, appropriate slice cutting was used to adjust the midline. At the 27th step, the upper anterior teeth were restarted to increase the torque of 10 degrees, so that the root was located in the cancellous bone, By optimizing the attachment to control the molar position, biteramp was not used in the whole process, and the pressure ridge was given by the upper anterior teeth technician to control the root.
