The most frequently impacted teeth are the lower third molars, followed by the upper canines, the two-thirds of which are positioned pallatinaly, then the lower second premolars, and the upper central incisors. It is very important that the right diagnosis is established early by a clinical examination and a radiological diagnostics. Also, it is recommended to utilize CBCT for determining the position of the impacted tooth in all three dimensions. The usage of the interceptive therapy makes it possible to prevent the occurrence of impaction and allow a spontaneous tooth eruption. If interceptive therapy can't be conducted or if it is not effective, the possible therapy choices are surgical-orthodontic treatment, autotransplantation, or extraction of the impacted tooth. Surgical-orthodontic treatment begins with an orthodontic space-making in order to position the impacted tooth in the dental arch if necessary, followed by the surgical procedure of exposing the crown of the impacted tooth, and ultimately by the orthodontic traction and the placement of the impacted tooth in the correct position. There are four main techniques of surgical exposure of the impacted teeth: gingivectomy, apically positioned flap, closed eruption technique, and pre-orthodontic surgical teeth exposure. The position of the impacted tooth is the main factor which influences the choice of the appropriate surgical exposure technique. Additionally, there are also other factors such as the age of the patient and the presence of the sufficiently attached gingiva. Although numerous complications can occur while treating the impacted teeth, they can be avoided by establishing an accurate and early diagnosis and by using the suitable surgical procedure and orthodontic biomechanics. For a successful surgical-orthodontic therapy which ensures optimal aesthetics and function, it is crucial to use both individual and interdisciplinary approaches and to establish diagnostics early.
