The bone integrated dental implants placement and the conventional acrylic estomatological prosthesis is a serious problem in patients with an atrophic alveolar edge. Ostheogenic distraction currently offers a potential solution to the severe loss of alveolar bone tissue. This study had the purpose of evaluate the effectiveness and stability of alveolar ostheogenesis. A Clinical Trial Phase II was conducted. Five patients with an atrophy of the jaw bone or maxillary alveolar edges were treated with intraoral alveolar distracters produced by Walter Lorenz Surgical Inc.(Rott-Nelson-1703-06-04) to induce ostheogenesis. They were all out patients. The latency period was of 1 mm/day and the contention period of 4 weeks. The effectiveness of the applied distraction was of a 76.3% and the stability of a 92.0%. The average of the total distraction obtained was of 7,25 mm. Ostheogenic distraction was an efficacious method to achieve the alveolar dent in patients with previous atrophy.
