Ectodermal dysplasia is a rare genetic condition characterized by abnormal development of skin, hair, nails, teeth and sweat glands. A young girl suffering from this condition came to our hospital seeking a fixed replacement of her missing teeth and to correct the shape of her chin which gave her an aged appearance. A 3D CT scan was taken to gauge the amount of residual bone. Due to the multiple missing teeth over a long period of time, the lower jaw bone was severely resorbed and the vertical height was insufficient to place implants. Maxillofacial Surgeon Dr. S.M. Balaji planned for a surgical reconstruction using alveolar distraction osteogenesis technique. The anterior region of the lower jaw bone was cut and alveolar distractor device was fixed. When the screw attached to the device is gradually turned 0.6 mm daily, the cut segments of bone move apart and new bone is formed in the resultant gap ultimately increasing the bone height which enhances her appearance.
