What Is Vertical Maxillary Excess<\/strong><\/strong>?<\/h2><\/div>\n\n\n\n
\n

Understanding Vertical Maxillary Excess<\/strong><\/strong><\/strong><\/h3><\/div>\n\n\n\n

Vertical maxillary excess is a skeletal condition characterized by excessive downward growth of the upper jaw, resulting in increased vertical facial height. This disproportionate vertical development can affect dental exposure, lip posture, and facial balance, often leading to a “long face” appearance and a “gummy smile”. Treatment commonly involves orthognathic surgery to reposition the upper jaw and, when necessary, the lower jaw, restoring facial height, correcting bite alignment, and improving overall facial balance.<\/p>\n<\/div>

Vertical Maxillary Excess<\/p>

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

Eating<\/h3><\/div>

Excess vertical growth can reduce effective bite force, making chewing less efficient and sometimes tiring.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

Speech<\/h3><\/div>

Speech is typically unaffected but may be influenced by excessive tooth or gum display, especially if an open bite is present.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

TMJ<\/h3><\/div>

Increased vertical dimensions can alter joint mechanics, occasionally leading to muscle fatigue or discomfort.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

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

This pattern is often associated with mouth breathing, which can contribute to ongoing facial growth changes.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

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

Nasal airway function may be compromised, contributing to inefficient breathing or snoring.<\/p><\/div><\/div>\n\n\n\n

\"\"<\/div>

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

Excessive gum display and elongated facial proportions can affect smile confidence and self-image.<\/p><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

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

Orthognathic surgery corrects vertical maxillary excess by repositioning the upper jaw to reduce excessive facial height, improve facial balance, and establish a more functional bite. Most commonly, a Le Fort I impaction is performed, sometimes combined with lower jaw surgery to optimize the result.<\/p><\/div><\/div>\n\n\n\n
