Odontogenic myxoma, a rare tumour that occurs in the jaws, locally invasive, destructive tumors that do not metastasize to lymph nodes. Large odontogenic myxoma on mandible is treated by mandibulectomy, defected mandible is reconstructed by bone graft. Reconstructed mandible is difficult to reconstruct dentition using implant because of deficiency of bone amount. So it is necessary to additional bone graft. But a poor aspect of soft tissue lead to unsatisfactory result. Because of distraction osteogenesis is possible to reconstruction of an amount of bone and soft tissue, that is advantage to reconstruction of alveolar bone on reconstructed mandible. We report with review of literatures the 25 years old male patient who had odontogenic myxoma in left mandible, was undergone mandibulectomy and successfully implant installation and prosthetic restoration after distraction osteogenesis(Track $Plus^{(R)}$, KLS Martin, Germany) on the reconstructed mandible with a free iliac bone graft, and we have conservative and successful result.

Introduction: Bone regeneration of cystic defects of the jaws after a cyst treatment requires lengthy healing periods. Generally, the bony changes are observed periodically through a visual radiographic reading as well as by the clinical opinion and radiographic images (panorama, periapical view), but it is difficult to compare the objective bony changes using only the radiographic density. In addition, it is difficult to observe minute bony changes through a visual radiographic reading, which can lead to a subjective judgment. This study exmined the bone density after the enucleation of a jaw cyst by fractal analysis. Materials and Methods: Eighteen patients with a cystic lesion on the jaw were assessed. Panoramic radiographs were taken preoperatively, immediately postoperatively, and 1, 3, 6 and 12 months after cyst enucleation. The images were analyzed by fractal analysis. Results: The mean fractal dimensions increased immediately after surgery and 3, 6 and 12 months postoperatively. The postoperative 6 and 12 months fractal dimension was similar to the controls. Conclusion: Fractal analysis was used to overcome the limit of a subjective reading during an assessment of bone regeneration after cyst enucleation.

Introduction: Mandibular third molar extraction is one of the most common procedures performed in oral and maxillofacial surgery units. Although the overall complication rate is low with most complications being minor, mandibular third molar removal is so common that the population morbidity of complications might be significant 1,2 . Therefore, efforts to limit intraoperative or postoperative complications might have a significant impact in terms of enhancing the patient outcome. The aims of this study were to identify the position and angulation associated complications after mandibular third molar extractions. Materials and Methods: This study surveyed 568 patients who had a mandibular third molar extracted, showed clinical complications and underwent a radiographic measurement of the available space, depth and spatial relationship. Results: The results obtained were as follows: 1. The complications were a dry socket, nerve injury, root rest, infection, bleeding, hamatoma, and adjacent teeth injury. 2. There were no significant differences between the complication and ramus relationship (available space) of the mandibular third molar. 3. There were no significant differences between the complications and depth of the mandibular third molar. 4. There were no significant differences between the complications and spatial relationship of the mandibular third molar. Conclusion: There were no significant differences in the complication rate, ramus relationship, depth and spatial relationship of the mandibular third molar. This suggests that the position and angulation of the mandibular third molar may not have an impact on the complications. The relationship between the position and angulation of the mandibular third molar, and complications deserves a further study using longitudinal data.

Cystic lesions in pediatric jaws can cause eruption disorders by displacing the erupting permanent teeth, and in the case of secondary infection, can cause swelling and pain. The treatment modalities for such cysts include cyst enucleation, marsupialization, and decompression. As compared to enucleation, decompression has the advantage of preventing damage to surrounding tissues and inducing spontaneous eruption of permanent teeth. We report a case where decompression was performed using a stent designed for decompression and as a space maintainer in three patients with eruption disorder due to cystic lesion of the jaw. The eruption of the displaced permanent teeth was successfully induced by maintaining the eruption space and removing the cyst.
