코멘트
- Retract lower anterior teeth to correct crossbite by distalization
- Align upper arch and correct midline by upper right distalization,achieve Class Ⅰ relationship of right canines and first molars
- Extract lingual 25 and close space by mesialization of 26 and 27 to achieve Class Ⅰ relationship of left canines.
- Designed paired attachments and overcorrection to control tipping of posterior teeth
- Improve tight occlusion by bilateral vertical elastic
- Use 5mm horizontal rectangular attachments on 1.6、2.6、2.7 and 4.6 to improve retention.
