Highlights

Tooth eruption is a multifactorial, individualized, and unpredictable process; comparison with the contralateral tooth is essential due  to expected bilateral symmetry.

Central incisor impaction was successfully managed through early
intervention and ongoing  adjustments during growth.

Regular orthodontic monitoring enables early correction of abnormalities, supporting proper growth and successful treatment outcomes.

Abstract

Delayed diagnosis of tooth eruption disturbances may result in the impaction of permanent teeth. This case report describes the clinical management of an impacted maxillary permanent central incisor in an 8-year-old boy with good general health, skeletal Class I relationship (ANB = 2°), posterior crossbite, and transverse maxillary deficiency. The patient underwent rapid palatal expansion, followed by orthodontic traction of the impacted incisor. Eruption was achieved within six months, and by the end of the mixed dentition stage, the patient exhibited a stable occlusion with successful alignment of the incisor. This case highlights the importance of early orthodontic assessment and continuous follow-up from the primary to permanent dentition. Timely diagnosis and treatment planning during growth can facilitate favorable outcomes and  reduce the risk of future occlusal  complications.
