Abstract

Unfavorable growth pattern in vertical direction, heredity, digital habits, tonque function, and habitual mouth breathing
are some abnormal functions that change the craniodentofacial morphology. This condition is also related with intensive
bad habit that is not realized by the anterior open bite patient. Elimination of the ethiology factor and patient motivation
influenced the success of anterior open bite correction. The aethiology of this anterior open bite can affect the treatment
time, result, and stability of treatment. This case report describes orthodontic treatment systematically of a 17.5-year-old
boy with retrognatic profile who had thumb-sucking habit in the past, infantile swallowing, and tongue-thrusting. The
type of anterior open bite was dental and malocclussion consisted of accentuated curve of spee at maxilla and reversed
curve of spee at mandible. The treatment started by correcting curve of spee along with instruction to keep oral muscle
activity in normal occlusal forces during orthodontic treatment. After the correction in vertical direction was achieved,
four-premolar extractions were done. The result after 19-month-treatment showed overcorrection of overbite of +3.5 mm,
overjet of +2 mm and tongue thrusting eliminated. In conclusion, the proper orthodontic treatment concurrently with bad
habit management in growing patient will affect the treatment result and stability.
