Abstract
In cases where anterior open bite is accompanied by maxillary posterior extrusion, it is necessary to apply orthodontic force for maxillary posterior intrusion during non-surgical treatment. Utilizing skeletal anchorage for maxillary posterior intrusion allows for non-surgical correction of anterior open bite, providing an aesthetically pleasing outcome without side effects such as unwanted extrusion of other teeth. This case report presents the non-surgical treatment of a skeletal anterior open bite patient, a 22-year-old woman, by applying maxillary posterior intrusion using mini-implants and incorporating the use of a Multi-Loop Edgewise Arch Wire (MEAW). The report also includes a two-year follow-up after treatment. The patient presented with anterior open bite, which was successfully corrected through maxillary posterior intrusion. Additionally, tongue exercises were performed during and after orthodontic treatment to correct tongue thrusting habits. During a follow-up visit two years after treatment, although there was a slight decrease in overbite, the occlusion remained stable, indicating a still successful and stable outcome.
