title: Patient with nonsyndromic bilateral and multiple impacted teeth and dentigerous cysts.
abstract: This article reports the successful treatment of a patient with the unusual occurrence of bilateral and multiple dentigerous cysts of the premolars. One impacted mandibular premolar was moved by traction orthodontically. On the opposite side, the impacted premolar was autotransplanted after space was created through mesial movement and hemi-sectioning of the neighboring molars. The impacted maxillary premolar was extracted. Miniscrews were additionally used for anchorage reinforcement to prevent unintended counteractions and solve the problem of space management after autotransplantation. We also reviewed the clinical implications of the diagnosis, planning, and treatment of cyst-associated impacted teeth in young adult patients.
