Orthodontic correction of a mandibular first molar deeply impacted by an odontoma: a case report.

Orthodontic correction was used to a 12-year-old boy with a mandibular first molar deeply impacted by an odontoma. Following surgical removal of the odontoma, the molar was exposed and brought to a proper position by orthodontic traction. The treatment time was 29 months. After a 20-month follow-up, the molar was still in a satisfactory position.
