Surgical-orthodontic correction of open-bite deformity

Area of Science:

• Oral and Maxillofacial Surgery
• Orthodontics

Background:

• Skeletal open-bite presents complex treatment challenges, often requiring surgical intervention.
• The combined simultaneous anterior and posterior maxillary ostectomy is a surgical technique developed for treating this condition.

Observation:

• The procedure is indicated for patients with lip incompetence, excessive maxillary incisor exposure, long lower face height, and Class II malocclusion.
• Contraindications include Class III skeletal open-bite and lip competence.

Findings:

• Clinical application over five years shows gratifying results with improved facial appearance and stable open-bite correction.
• A recent study of 32 patients followed for 1.5 years demonstrated excellent long-term stability of vertical maxillary repositioning.

Implications:

• This surgical method provides a reliable option for skeletal open-bite correction, enhancing patient outcomes.
• Careful surgical planning and execution, coordinated with orthodontic treatment, are crucial for optimal and stable results.
