ABSTRACT

BACKGROUND: Anterior open bite can negatively impact facial aesthetics, as well as cause functional impairment and social challenges. We present the case of an adolescent patient with a severe anterior open bite.

METHODS: After an initial phase of expansion using an expander on palatal mini-screw implants, the patient was treated with a fixed buccal appliance and intermaxillary elastics. Skeletal anchorage was used to achieve effective posterior control. Finally, minor finishing was performed with aligners, and the case was completed with multiple restorations of the teeth.

RESULTS: The combination of a fixed appliance and intermaxillary elastics resulted in the extrusion and retroclination of the maxillary incisors, leading to bite closure. Successful results were achieved, with good occlusion, improved facial aesthetics, and stability maintained over the 2-year retention period.

CONCLUSIONS: Temporary anchorage devices offer reliable anchorage for posterior vertical control. With appropriate treatment planning -taking into account incisor display, growth potential and biomechanics- this approach can serve as a non-surgical alternative for managing severe open bite cases.
