What Is Anterior Open Bite<\/strong><\/h2><\/div>\n\n\n\n
\n

Understanding Anterior Open Bite<\/h3><\/div>\n\n\n\n

Anterior open bite is a condition where the upper and lower front teeth do not touch when the mouth is closed, leaving a visible gap. This can affect chewing, speech, and overall bite function, and may also influence facial balance. Management may include orthodontics, jaw surgery, or a combination of both depending on the cause.<\/p>\n<\/div>

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

\"Icon<\/div>

Eating<\/h3><\/div>

Lack of contact between the front teeth makes biting into foods difficult, shifting function to the back teeth.<\/p><\/div><\/div>\n\n\n\n

Speech<\/h3><\/div>

Speech may be affected for sounds that require tongue\u2013incisor contact, such as \u201cs\u201d and \u201cz,\u201d resulting in a lisp.<\/p><\/div><\/div>\n\n\n\n

TMJ<\/h3><\/div>

Altered bite relationships can place abnormal forces on the joints, especially if compensatory movements are present.<\/p><\/div><\/div>\n\n\n\n

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

Often associated with tongue posture or habits that promote mouth breathing and affect bite development.<\/p><\/div><\/div>\n\n\n\n

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

Nasal airway patterns may be altered, especially if habits or skeletal factors contribute to the open bite.<\/p><\/div><\/div>\n\n\n\n

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

Orthognathic surgery corrects anterior open bite by impacting the posterior maxilla to allow the front teeth to come together properly, often combined with lower jaw repositioning. Most commonly, double jaw surgery is performed, combining Le Fort I osteotomy and BSSO to improve bite, function, and facial balance.<\/p><\/div><\/div>\n\n\n\n
