Summary
This study explores orthodontic treatments for dental and skeletal asymmetries, including mandibular deviations. Effective management requires tailored mechanics, sometimes involving extractions, and multidisciplinary approaches for optimal outcomes.
Area of Science:
- Dentistry
- Orthodontics
- Craniofacial Biology
Background:
- Dental and skeletal asymmetries present significant clinical challenges in orthodontics.
- These asymmetries are categorized into mandibular lateral deviations, dental asymmetries without skeletal involvement, and skeletal asymmetries.
Observation:
- Vertical non-surgical asymmetry often lacks an evident origin, but occlusal slippage in severe malformations is a suspected cause.
- Diagnosis is frequently delayed until after growth completion, necessitating specialized asymmetric mechanics and sometimes unilateral mixed extractions.
- Adult patients with severe dentofacial asymmetries benefit from multidisciplinary treatments focusing on facial aesthetics and functional anomalies like TMJ disorders and dental wear.
Findings:
- The study presents various orthodontic means for treating asymmetries, illustrated by four clinical case reports.
- Asymmetric mechanics and careful finishing steps are crucial for stable post-treatment occlusion.
- Multidisciplinary treatments are highly effective for complex cases, including transverse anomalies, crossbites, and midline deviations.
Implications:
- Tailored orthodontic mechanics and multidisciplinary collaboration are essential for successful management of diverse asymmetries.
- Addressing dental and skeletal asymmetries improves both facial aesthetics and functional outcomes in patients of all ages.
- Early diagnosis and intervention, where possible, can optimize treatment results and long-term stability.
