Bemerkungen
Step 1. Adopt the maxillary maximum molar anchorage design, cooperate with class II elastic, and retract anterior teeth maximum to make the anterior teeth upright in the center of alveolar bone, which can better improve the thickness and valgus of the patient's lip;
Step 2. Adopt the step-by-step method to retract the upper anterior teeth to save the molar anchorage. Firstly the upper canine moves 1 mm distally, and then retract the anterior teeth together to avoid the pendulum during space closing;
Step 3. When moving 34 / 44 half of the distal, retract the anterior teeth to avoid the lingual inclination of the lower anterior teeth and maintain good overbite during space closing;
Step 4. Pull out 35 / 45, make rational use of the extraction space, not only move the molar forward to adjust the molar relationship but also retract the lower anterior teeth, so that the lower anterior teeth stand upright in the center of the alveolar bone and shape a good mental shape;
Step 5. Pull out 35 / 45, move the molars forward step by step, cooperate with class II traction, move the lower molars forward, and adjust the class Ⅰ molar relationship;
Step 6. The 36 / 46 is designed with double rectangular attachments to avoid mesial inclination during space closing.
