Open bite, dental alveolar protrusion, class I malocclusion: A successful treatment result.

This case report describes the treatment of a dentoalveolar protrusion, Class I malocclusion with an anterior open bite. The 21-year-old woman presented with a significant anteroposterior and vertical skeletal discrepancy. Her face was convex with procumbent lips. Intraorally, she had an anterior open bite of 4 mm, mild crowding, and an overjet of 4.5 mm. First premolar extractions in conjunction with tongue therapy and high pull headgear were used to reduce protrusion and close anterior open bite. Modification of a tongue thrust habit allowed conventional orthodontic treatment to correct this significant malocclusion and provide stability over the last 4 years.
