What Is Mandibular Retrognathia?<\/h2><\/div>\n\n\n\n
\n

Understanding Mandibular Retrognathia<\/h3><\/div>\n\n\n\n

Treatment often involves orthognathic surgery to advance the lower jaw and, when necessary, reposition the upper jaw to correct the underlying skeletal imbalance, restoring proper function, improving facial proportions, and relieving strain on the jaw joints and surrounding structures.<\/p>\n<\/div>

Frontal View<\/span>

Frontal Analysis<\/h3><\/div>

In mandibular retrognathia, the lower jaw is positioned behind the upper jaw, often affecting the balance of the lower face. The chin may appear less prominent, with reduced definition in the lower third.<\/p><\/div><\/div>\n\n\n\n

Profile Analysis<\/h3><\/div>

From the side, mandibular retrognathia is characterized by a retruded lower jaw, creating a convex facial profile. The chin appears recessed relative to the upper jaw and midface.<\/p><\/div><\/div>\n\n\n\n

Mandibular Retrognathia<\/p>

Common Functional Issues<\/h2><\/div>\n\n\n\n
\n
\"\"<\/div>

Eating<\/h3><\/div>

Reduced lower jaw projection can make biting into foods difficult and may shift chewing function toward the back teeth.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

Speech<\/h3><\/div>

Speech clarity may be affected, particularly with sounds requiring precise tongue-to-tooth contact.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

TMJ<\/h3><\/div>

A retruded jaw position can strain the joint and surrounding muscles, sometimes leading to pain, clicking, or limited opening.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

Mouth Breathing<\/h3><\/div>

A smaller lower jaw can reduce airway space, increasing the likelihood of mouth breathing, especially during sleep.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

Nasal Congestion<\/h3><\/div>

Restricted nasal airway dimensions may contribute to inefficient nasal breathing and potential sleep-disordered breathing.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

Psychosocial Effects<\/h3><\/div>

A recessed chin and profile can affect facial harmony, sometimes leading to concerns about appearance or confidence.<\/p><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

Mandibular Retrognathia<\/span>

Jaw Surgery Procedures<\/h2><\/div>

Orthognathic surgery corrects retrognathia by advancing an underdeveloped lower jaw and, when needed, repositioning the upper jaw to restore proper bite and facial balance. Most commonly, double jaw surgery is performed, combining BSSO (mandibular advancement) and Le Fort I osteotomy to create a more balanced, harmonious result.<\/p><\/div><\/div>\n\n\n\n
