A surgery to correct protruding upper and lower jaw by performing anterior segmental osteotomy (ASO) or orthognathic surgery.
Overview
Protruding mouth (bimaxillary protrusion) is a condition where the alveolar bone (the bone supporting the teeth) protrudes forward, making the mouth appear prominent in profile. Anterior segmental osteotomy (extracting premolars and moving the anterior alveolar bone backward) is the representative technique. If the entire skeletal structure is involved, orthognathic surgery may be required instead.
Mechanism
Anterior segmental osteotomy (ASO) extracts premolars, then cuts and repositions the anterior alveolar bone segment backward to reduce protrusion. If the entire jaw is involved, full orthognathic surgery (Le Fort I or BSSO) may be required. The bone segment is fixed with titanium plates in the retracted position.
Effects
Reduced mouth protrusion in profile, improved lip posture and competence, more balanced facial proportions, improved smile aesthetics, and correction of dental protrusion.
Duration
Permanent. Bone healing at 6-8 weeks. Orthodontic finishing may take 6-12 months. Final soft tissue change at 3-6 months.
Recovery
Swelling for 2-3 weeks. Liquid to soft diet for 2-4 weeks. Numbness around chin and lower lip for weeks to months. Return to work at 1-2 weeks. Full recovery at 2-3 months.
Side Effects
Numbness of chin and lower lip (temporary or rarely permanent), infection, tooth root damage, bone non-union, relapse, and gingival recession. Extraction gaps require orthodontic closure.
Price Range
5,000,000-12,000,000 KRW depending on surgical approach.
Target Audience
Those with bimaxillary protrusion (protruding mouth), those with dental protrusion affecting facial profile, and those seeking correction of mouth prominence.
