Abstract
A girl, aged 8-years and 10-months old, was brought to our hospital for treatment of the maxillary impacted supernumerary teeth. A radiographic examination revealed that the right maxillary central incisor was impacted, and two supernumerary teeth were located palatal to the left maxillary central incisor and nasally to the impacted right maxillary central incisor.
The right maxillary central incisor was planned to be preserved in this patient. The left supernumerary tooth was first extracted, and through the extraction space, the right supernumerary tooth was exposed and removed. Orthodontic therapy was then performed using a maxilla fixing device and sectional arch to gradually bring the right maxillary central incisor to its proper position. Since the patient's family was planning to move in one year, multibrackets were used during this period to achieve favorable tooth position and occlusion.
In this patient, it was difficult to bring the inverted and impacted central incisor to the proper position orthodontically. Thorough examination and good clinical skills were required to perform the or thodontic therapy, while preserving the dental pulp without damaging the root apex of the central incisor. The impacted supernumerary teeth had to be carefully removed to prevent damage to the central incisor.
The patient and her parents were satisfied with the treatment outcome. In addition to promoting oral development, we were able to gain knowledge and improve our clinical skills.
