Tooth ankylosis can lead to chewing function abnormality and a bad bite, resulting in an esthetically unappealing smile line. The dentoalveolar distraction osteogenesis method is a good option for the treatment of an ankylosed tooth, as it facilitates both hard and soft formation and repositioning of the tooth. Successful repositioning of an ankylosed tooth improves both function and esthetics. In this clinical case report, we describe the treatment of an ankylosed maxillary central incisor in a 21-year-old female using a simple tooth-derived intraoral distractor. An expansion screw and stainless-steel wire were used in the construction of the distractor. This intraoral apparatus provided ease of movement of the dentoalveolar segment after the osteotomy. After repositioning the central incisor by distraction osteogenesis procedure improvement of chewing function and smile esthetics achieved. The dentoalveolar distraction osteogenesis method using a tooth-borne distraction device can yield good results in patients with tooth ankylosis.
