What Is Jaw Misalignment or Jaw Irregularity?

Jaw irregularities, also known as skeletal jaw discrepancies, occur when the upper and lower jaws are not properly aligned. This can lead to an unbalanced facial profile, an asymmetrical appearance, and functional problems like difficulty chewing, speaking, or breathing.

Common jaw concerns include:

• Underbite (protruding lower jaw)
• Overbite (receding lower jaw)
• Open bite (teeth don’t meet when the mouth is closed)
• Facial asymmetry
• A long or short lower face
• Jaw joint pain (TMJ issues)

These issues are often skeletal, meaning they cannot be corrected by braces or fillers alone.

What Is Jaw Surgery (Orthognathic Surgery)?

Jaw Surgery is a bone repositioning procedure that corrects the alignment and shape of the upper jaw (maxilla), lower jaw (mandible), or both, to achieve a harmonious facial profile and balanced bite.

At Seoul Cheil Plastic Surgery, jaw surgery is meticulously planned and performed by experienced surgeons using advanced 3D imaging for precision. Types of jaw surgery include:

• Two-Jaw Surgery (Bimaxillary Osteotomy): Corrects both the upper and lower jaws
• Mandibular Setback Surgery: Moves the lower jaw backward for an underbite
• Le Fort I Osteotomy: Moves the upper jaw for a gummy smile or open bite
• Sliding Genioplasty: Refines the chin for profile harmony
• Surgery time: 3–5 hours under general anesthesia

Why Combine Jaw Surgery With Other Procedures?

For a complete facial transformation, jaw surgery is often combined with:

• Chin reshaping (genioplasty) for profile balance
• Cheekbone reduction for facial width harmony
• Forehead or temporal augmentation for a softer upper face
• Fat grafting to restore volume and create smooth contours

This holistic approach ensures a balanced, natural-looking result.

Key Characteristics of a Face That May Benefit From Jaw Surgery

• Underbite or overbite (misaligned bite)
• A long, short, or asymmetrical face
• A weak chin or protruding jaw
• Difficulty chewing or closing lips naturally
• Jaw joint discomfort or TMJ pain
• A bulky or undefined lower face

Can Braces or Fillers Fix Jaw Irregularities?

For mild alignment issues, braces can help adjust teeth, but they:

• Cannot reposition the jawbone
• Cannot correct chin shape, facial proportions, or asymmetry

Fillers can add temporary volume, but they cannot address skeletal structure.

For true skeletal issues, jaw surgery is the only permanent solution for both functional and aesthetic improvement.
