• The crowding is removed first. The upper and lower incisors should be depressed, after the front teeth are aligned, and then adduction should be completed.
• During the adduction, the gap between the canines and incisors should be kept at 1mm to enhance the wrapping control of the incisors.
• The right lower molars are distributed in mesial movement, one by one, and adjusted to a neutral relationship
• Maxillary wisdom teeth have been retained during the orthodontic process. Maxillary wisdom teeth are included in treatment, but not designed to move, only to enhance maxillary anchorage.
