A tooth emerges into the oral cavity after developing a half or three-quarters of its root. However, various local, systemic, and genetic factors and their interactions can cause tooth impaction. The most frequently impacted teeth in the maxilla are the third molars, followed by canines, second premolars, and central incisors. Since impaction is mostly asymptomatic, it is generally diagnosed late. Diagnosis is established based on clinical examination and radiographic imaging. Treatment involves an interdisciplinary approach that includes general dentists, orthodontists, surgeons, and sometimes periodontists. Depending on the patient's age and the position of the impacted tooth, orthodontists and surgeons choose an interceptive treatment approach, orthodontic therapy, or surgical exposure of the tooth. If the diagnosis is made at an early stage, an interceptive approach to treatment is possible. However, sometimes this is not sufficient, thus surgical exposure of the impacted tooth is necessary. Orthodontic-surgical therapy of impacted teeth involves surgical exposure of the tooth followed by orthodontic traction, correction of the root and crown inclination, and alignment of the teeth in the dental arch. There are three methods of surgical tooth exposure: closed eruption method, open eruption method, or apically repositioned flap. Choosing an inappropriate method of surgical exposure or applying inadequate orthodontic forces can result in undesirable outcomes such as bone loss, tooth loss, root resorption, gingival recession, or differences in the length of the tooth crowns. With an individualized and interdisciplinary approach, collaboration among general dentists, orthodontists, surgeons, and periodontists, an selecting appropriate therapy based on the patient's age and tooth position, as well as recognizing potential complications, impacted teeth can be successfully treated.
