The aim of this case re- port is to describe a method to treat an- kylosed teeth, as an alternative to avul- sion and replantation procedures.
MATERIALS AND METHODS.
The case of a 13-year-old patient is presented, who was subjected to a single tooth den- to-osseous osteotomy for the treatment of an ankylosed and infraoccluded max- illary right central incisor.
RESULTS
Short term evaluation re- vealed a good soft tissue healing. After 6 months, there was no evidence of relapse in the tooth position.
The post-treatment panoramic radio- graph showed good bone regeneration around the segmental osteotomies.
CONCLUSIONS
Single-tooth osteotomy to reposition an ankylosed tooth, in con- junction with orthodontic treatment, is a predictable and successful procedure. This technique enables the repositioning of the ankylosed tooth, while preserving the alveolar bone.
