In anterior maxilla edentulous cases, sufficient bone is important to succeed both in consolidation of a fixture and aesthetic form. Therefore, alveolar ridge augmentation is performed to obtain sufficient bone for implant treatment. However, the augmentation, performed in the vertical dimension, has been difficult compared with other augmentations, because of frequent complications, such as infection, bone resorption, etc. Distraction osteogenesis has been produced for jaw bone lengthening. Continuously, alveolar bone lengthening which was used distraction osetogenesis was reported with good results. This method is able to obtain any direction and volume as bone augmentation. As such, we performed vertical augmentation in an anterior maxilla edentulous case using this method. Osteotomy and placement of distraction device were performed to the patient who was contracted vertical bone resorption. After 10 days, the device was activated once or twice daily for 8 days (total lengthening was 7.0 mm). After 8 weeks, the device was removed, and after 4 weeks, implant fixtures were inserted. Local infection occurred during lengthening, but a sufficient bone volume was obtained. Our result suggested that distraction osteogenesis was useful for alveolar bone augmentation in the anterior maxilla.
