Dilaceration is most common in maxillary central incisor. Impaction by dilacerated tooth cause orthodontic problem such as tilting of adjacent tooth, midline deviation.

Dilaceration is caused by trauma, cyst, other origin and tooth shape, degree of root curvature, location in the alveolar bone, ability of spontaneous eruption should be considered whether treat or not.

Labially and lingually dilacerated tooth is difficult to spontaneous eruption. Thus, Prosthetic treatment alternative with extraction, auto transplantation, orthodontic traction with surgical exposure is included within the treatment alternative.

These cases are about impacted central incisor with dilacerated root. We use closed eruption technique and guide impacted tooth into normal position by orthodontic traction.
