Orthodontic Camouflage Treatment for Skeletal Class III Patient

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.
