Treatment of an ankylosed central incisor by single-tooth dento-osseous osteotomy

This article presents a case of an ankylosed upper central incisor that did not respond to orthodontic mechanics alone or to surgical luxation followed by orthodontic traction. We performed an osteotomy involving the dento-osseous segment in one surgical stage to allow its inferior displacement. The patient was followed for 18 months and the result was considered satisfactory from both the occlusal and periodontal standpoints.
