Bi-maxillary advancement surgery: Technique, indications and results

Area of Science:

• Maxillofacial surgery
• Orthodontics
• Facial aesthetics

Background:

• Dental Class II malocclusions can present esthetic concerns requiring surgical intervention.
• Mandibular advancement alone may resolve occlusal issues but lead to unsatisfactory facial results.

Observation:

• Esthetic analysis in Class II patients sometimes indicates a need for maxillo-mandibular advancement.
• Facial analysis reveals that isolated mandibular advancement can be esthetically displeasing.

Findings:

• Bi-maxillary advancement surgery effectively reduces the impact on nasal volume and corrects the nasolabial relationship.
• This technique increases sub-mandibular length, creating a more defined cervico-mental angle.
• A staged approach, starting with mandibular advancement, restores occlusion and optimizes facial esthetics.

Implications:

• Bi-maxillary advancement offers a comprehensive solution for Class II malocclusions, addressing both functional and esthetic deficits.
• This surgical strategy enhances patient outcomes by improving facial harmony and dental occlusion.
• The findings support the use of bi-maxillary advancement for optimizing esthetic and occlusal results in select patients.
