Impacted teeth are a common clinical finding in orthodontic practice and can significantly affect dental aesthetics, occlusal function, periodontal health, and overall treatment outcomes. The most frequently impacted teeth include third molars, maxillary canines, premolars, and supernumerary teeth. Successful management of impacted teeth requires accurate diagnosis, interdisciplinary treatment planning, and appropriate orthodontic and surgical interventions. Recent advances in diagnostic imaging, cone beam computed tomography (CBCT), digital treatment planning, temporary anchorage devices (TADs), and surgical exposure techniques have improved treatment predictability and outcomes. This review examines the etiology, diagnosis, classification, treatment options, biomechanics, complications, and future directions in the orthodontic management of impacted teeth. The study highlights the importance of individualized treatment planning and multidisciplinary collaboration in achieving optimal functional and aesthetic results.
