Background:
Anterior open bite is a kind of malocclusion that can affect the oral function, aesthetics and even mental health of adolescents. Breaking harmful habits plays an important role in the orthodontic treatment of patients during the growth and development period.
Case Presentation:
This case focuses on a 13-year-old adolescent male with anterior open bite of 6 mm, Class II malocclusion, and finger sucking, tongue thrusting habits, and abnormal swallowing pattern. Based on the etiology and the patient's condition, a treatment plan involving extraction of second premolars and use of an adhesive tongue crib was implemented. After 35 months of active treatment and 12 months of retention, results showed improved occlusion, normal overbite and overjet, proper molar relationships, and enhanced facial aesthetics. The study highlights addressing etiological factors and using appropriate treatments. A modified Hawley retainer and a retainer with a welded tongue crib at night helped maintain results due to the patient's history and potential for recurrence.
Conclusions:
For adolescent patients with anterior open bite, clear diagnosis and elimination of causative factors are key to favorable treatment results. Combining multiple mechanisms can effectively restore and establish a good occlusal relationship. Throughout the treatment, it is also necessary to pay attention to patients' growth and development.
