Tooth impactions are rarely found in the maxillary second premolars. The common treatment modalities are as following: tooth extraction, surgical exposure, surgical exposure with orthodontic tracing, tooth extraction with autotransplantation of the supernumerary tooth or the other tooth, and surgical reposition. This article presents a 13-year-old female patient with an impacted maxillary second premolar which is incomplete root formation. The impacted tooth was surgically repositioned to normal occlusion. After more than 1 year follow-up, the pulp vitality test of the tooth was positive and the root was continued to develop.
