Orthodontic treatment was performed with a Roth prescription fixed appliance and alignment and leveling with NiTi wires. Upon reaching the rectangular wire, an interradicular mini-implant was inserted between the maxillary right lateral incisor and the maxillary right canine (teeth 12 and 13) as an anchorage for intrusive mechanics in this region. Also, during this phase, the extrusion of tooth 23 was performed to level the gingival margin in relation to the incisors. After 11 months, the inclination of the occlusal plane in a smiling frontal view was corrected and the finishing phase began. At the end of the treatment, tooth 23 was re-anatomized, transforming it into a lateral incisor, which resulted in an aesthetic and harmonious smile. Through this clinical case, it is concluded that the frontal inclination of the occlusal plane of dentoalveolar origin can be corrected with the help of skeletal anchorage in cases where there is good gingival exposure in the anterior region.
