An anterior open bite is a type of malocclusion where the upper and lower front teeth do not touch when the back teeth are together, leaving a vertical gap between them.
🦷 Types of Anterior Open Bite
1. Dental open bite
-Caused primarily by the position of teeth.
-Teeth fail to erupt properly in the anterior region.
-Often linked to habits like thumb sucking or tongue thrusting.
2. Skeletal open bite
-Caused by jaw growth discrepancies.
-The upper and/or lower jaw grows in a way that prevents front teeth from contacting.
-Often associated with long face syndrome.
⚠ Causes
-Oral habits: thumb sucking, pacifier use, tongue thrusting.
-Skeletal growth problems: excessive vertical growth of the jaw.
-Genetic factors.
-Airway issues: mouth breathing leading to altered jaw posture.
-Temporomandibular joint problems or trauma.
🔍 Clinical Features
-Visible gap between upper and lower front teeth when back teeth are together.
-Difficulty biting into foods like sandwiches or apples.
-Speech problems (lisping or improper tongue placement).
-Aesthetic concerns (long facial appearance or “gummy” smile)
