Cone-beam computed tomography (CBCT) images, clinical photographs, and surgical procedure for our patient with nasally impacted inverted mesiodens. (A) Axial view of CBCT showing a mesiodens slightly to the left of the midline, occupying the nasopalatine duct. (B) Coronal view of CBCT revealing the mesiodens elevating the nasal floor, with a prominent dental follicle space occupying the upper portion of the nasopalatine duct. (C) Sagittal view of CBCT showing the deeply inverted position of the mesiodens crown in the crista nasalis, attached to part of the nasal septum and in close proximity to the adjacent root of the left maxillary central permanent incisor. (D) Surgical marking pen used to outline the curvilinear vestibule incision line at the vestibule bottom from the canine-to-canine region. (E) A mucoperiosteal incision made from the canine-to-canine regions, followed by the use of a vestibular flap to expose the pyriform apertures. (F) A facial slot osteotomy performed to access and expose the mesiodens. (G) Extraction completed with minimal elevation of the nasal mucosa and without dislocating the nasal septum. (H) The mesiodens was removed with crown dissection. (I) An alar cinch was performed through the anterior nasal spine using 4-0 VICRYL before closing the surgical wound with 4–0 chromic gut sutures.
