maxillofacial surgeons have attempted to achieve anatomic reduction through the open approach and extracorporeal reduction and fixation. However, when using this method, there is some risk of resorption of the fractured mandibular condylar head. Therefore, we designed a modified extracorporeal reduction technique, without detaching the lateral pterygoid muscle in order to maintain the blood supply to the fractured mandibular condylar head. We believe that this minor modification may minimize the risk of resorption of the fractured mandibular condylar head. In this article, we introduce this technique in detail, and report on two cases.]]>

maxillofacial regions.METHODS: A retrospective observational study was conducted on 164 patients who had been diagnosed with cyst of the jaw, from the database of 168 histopathological diagnoses at the Department of Oral and Maxillofacial Surgery of Busan Paik Hospital at Inje University, from January 2009 to December 2011. The subjects were treated and the following variables were recorded: gender, age, clinical signs and symptoms, histopathological distribution, treatment methods, and complications. A descriptive analysis of the study variables was performed using a chi-square test.RESULTS: Among the 164 patients, there were more male than female patients (male-female ratio: 1.7:1). The most predominant ages were the 20s and 40s. Among the classes of pathological cysts, radicular cysts and dentigerous cysts were the most common, with incidences of 56.0% and 35.1%. Thirty-six percent of the patients had no symptoms; and of those who had symptoms, the main signs and symptoms were swelling (24.4%) and pain (17.1%). The most frequent management method was the combination operation, such as enucleation with or without extraction and apicoectomy of the causative teeth. Of the 164 patients, 13 had complications; and one patient who had been treated with enucleation with apicoectomy had a recurrent cyst.CONCLUSION: Using a chi-square test, no significant differences in prevalence were observed in relation to gender according to age. Comparative analysis of radicular and dentigerous cysts showed a significant difference in their prevalence according to their anatomical location, however, no significant differences in were observed in their incidence rates according to age.]]>

maxillofacial area, bone defects are created by various reasons and demand for bone grafts, while dental implant implantation has been increased consistently. To solve these problems, there has been development of autogenous tooth-bone graft material (AutoBT(R), Korea Tooth Bank Co., Korea), and we have collected ground reasons to substitute free autobone graft with this material in clinical use. This autogenous tooth-bone graft material is produced in powder type and block type. Block type is useful in esthetic reconstruction of the defect site and vertical and horizontal augmentation of alveolar bone because this type has high strength value, well maintained shape and is less absorbed. Therefore, the author of this study gained favorable result by grafting the block type autogenous tooth-bone graft material after dental implant implantation on the bone defects of the mandibular molar extraction site. Moreover, the author represents this case with literature review after confirming bone remodeling on the computed tomography image and by histological analysis.]]>
