Summary
This study shows that using temporary anchorage devices (TADs) with facemask therapy effectively corrects skeletal Class III malocclusion in post-pubertal patients, achieving stable results without adverse effects.
Area of Science:
- Orthodontics
- Dentofacial Orthopedics
- Maxillofacial Surgery
Background:
- Skeletal Class III malocclusion treatment is well-established in early growth stages.
- Limited evidence exists for treating adolescents and adults with Class III malocclusion.
Observation:
- A 13-year-5-month-old female presented with skeletal Class III malocclusion, transverse deficiency, high mandibular plane angle, and anterior crossbite.
- Treatment involved a TAD-supported Haas rapid palatal expander for maxillary protraction, vertical control, and molar distalization.
Findings:
- Facemask therapy with TADs achieved significant skeletal and dental correction in a post-pubertal patient.
- Treatment resulted in an improved facial profile and excellent stability over 18 months of retention.
- The approach prevented maxillary molar tipping and maintained vertical dimension control.
Implications:
- TAD-supported maxillary expansion and protraction offer a viable treatment for Class III malocclusion in older patients.
- This method minimizes risks of unfavorable periodontal consequences and uncontrolled vertical changes.
- It provides a stable and effective alternative for complex dentofacial deformities.
