Issues:

?Profile: Concave facial profile with maxillary retrusion and mandibular protrusion.

?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.

?Transverse: Narrow upper arch.

?Vertical: Deep bite.

?Sagittal: Bilateral posterior crossbite in full intercuspation, anterior overbite.

Diagnosis:

?Skeletal Class III.

?Angle Class III.

?Anterior crossbite.

?Open bite.

?High-angle.

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.
