Herein, we described the multidisciplinary treatment of a mixed dentition patient with impacted maxillary right central incisor and adjacent compound odontoma. In contrast to conventional treatment procedures, orthodontic traction was first performed for the affected tooth in this case, followed by resection of the odontoma. The odontoma did not shift after eruption of the incisor and was safely removed after alignment of the impacted tooth. No root resorption, gingival recession or bone defect occurred in this case. These results demonstrated that the orthodontic force can break the connection between the impacted tooth and the odontoma. The increased distance between the impacted tooth and odontoma may facilitate removal of the odontoma. Adhesion between the soft tissue capsule of odontoma and the dental follicle, rather than blocking the tooth, may play a role in tooth impaction.
