?Skeletal: Class III malocclusion.
?Dental: Upper incisors inclined labially, lower incisors inclined lingually, anterior crossbite, open bite, upper arch with 1° crowding, lower arch with 3° crowding.

Treatment Approach and Plan:
Option 1: Initial orthodontic-orthognathic combined treatment.
Option 2: Orthodontic camouflage treatment.
①Expand the upper arch with a fixed helical expander.
②Extract 34 and 44 in the lower arch to address anterior crowding and relieve anterior crossbite/open bite.
Summary---Successful details in orthodontic camouflage treatment:
?Vertical Control: Helical expander controls molar height, preventing extrusion, and increasing the subapical third length.
?Transverse Control: Matching the width of upper and lower dental arches.
?Sagittal Control: Strategic extraction of a single tooth, achieving full intercuspation in the molar relationship with clear treatment goals.
