The present report aimed to explore the case of an ۸-year-old patient with chief complaint of the lack of eruption of the maxillary right permanent central incisor, referring to the Department of Pediatric Dentistry, Faculty of Dentistry, Hamadan University of Medical Sciences. The corresponding tooth on the contralateral side had fully erupted. The patient’s history revealed that the predecessor deciduous tooth had sustained a trauma, resulting in the partial intrusion of the tooth into the alveolar bone, that is, the relative intrusion of the deciduous central incisor. CBCT examinations were ordered for further evaluation, which showed the upward displacement of the permanent tooth bud in the alveolar bone as a result of the trauma, adhering to the floor of the nasal cavity. Therefore, root formation was halted, making the tooth embedded.
