    • Abstract:
      Alveolar Distraction is a method for reconstructing a deficient or atrophic alveolar bone. Alveolar ridge reconstruction may be indicated for the atrophic alveolar process resulting from maxillofacial trauma, periodontal disease, or post aggressive large cyst or tumor resection. The aim of this paper is to demonstrate the method of reconstruction of the alveolar ridge by Distraction Osteogenesis. A total of 32 patients were treated. An alveolar segmental osteotomy was carried out and the distraction device was mounted. In patients with an extensive alveolar defect two distraction devices were placed in order to better control the vector of elongation in both bone edges. The distraction was started on the fourth post-operative day at a rate of 0.5 mm/day as necessary and according to the length of the distraction device, followed by a consolidation period of 90 days. Subsequently, the devices were removed, and dental implants were placed for osteointegration. The amount of elevation was 8-15mm. All the patients had panoramic x ray before the distraction, during the lengthening, at the end of distraction and after removal of the device. Early mineralization in the distracted area was seen radiographically during the consolidation period that increased after device removal. As a result of alveolar distraction, a segment of mature bone was transported vertically in order to lengthen the crest for better implant anchorage, either for esthetic purposes or for functional prosthetic requirements. A total of 68 implants were introduced. In follow-up at 24 months, failure of only one implant was noted, due to inadequate transported bone stability. In conclusion, distraction osteogenesis is an alternative treatment in moderate to severe alveolar deficiencies for an ideal three-dimensional reconstruction with no need for bone harvesting. This method offers the possibility to place dental implants in a correct position to obtain proper prosthetic results.
