We report a case in which a right mandibular incisor was impacted beneath an odontoma in the anterior mandible. An odontoma at the symphyseal region was removed under general anesthesia, and bone was grafted. Tooth #41, which was beneath the lesion, was extracted and transplanted to its original site. It was splinted with resin for 2 weeks and was checked at intervals during that time. After 4 months, it was filled endodontically with calcium hydroxide.
