  • 현재 악안면 보철 제작에 있어 재료로 실리콘이 제일 많이 사용되고 있으나 이 재료는 시간이 지남에 따라 점차 굳어져 가고 탄력성을 잃으며 원래의 색도 노랗게 변색되어 간다는 단점이 있다. 이러한 재료의 화학적 구성 단점 때문에 보철 생명력을 유지하기 위하여 환자들은 매 3년마다 새로운 보철물을 재 제작하여야 한다. 그렇다면 복잡했던 악안면 기공 과정을 다시 반복해야 하는 시간적, 물질적 손실을 감수해야 했다. 이러한 단점들을 보완하고 환자 피부색과 적합이 잘 되는 다양한 색의 실리콘 개발과 아울러 눈동자를 깜빡일 수 있는 인공 눈동자의 개발 등이 필요하며, 눈동자를 만드는데 사용되는 인공 수정체의 발전이 향후 악안면 보철 분야의 큰 과제라 할 수 있다.

  • Ameloblastomas are generally considered to be benign tumors of odontogenic epithelial origin with high local recurrence. Rarely ameloblastomas exhibit malignant behavior with development of metastases. In this report, we present a 19-year-old woman with ameloblastoma in the right ascending ramus and multiple recurrences. Eleven years after first therapy, ameloblastoma metastasized to ipsilateral submandibular lymph node. We also review literature about cause, treatment and work-up of malignant ameloblastoma.

  • Purpose: Craniofacial structure form results from the adaptation to morphologic and functional changes in their neighboring structures for a mutual balance. The purpose of this study is classification of maxillomandibular complex growth pattern follow by cranial base growth pattern. And this study is identifying the correlation between maxilla-mandibular complex growth pattern and orthodontic criteria. Methods: 142 Class III malocclusion patients had orthognathic surgery at Wonkwang University Dental Hospital during April 2004 to October 2010. Patients were divided into 4 groups and the correlation between cranial base and maxillomandibular growth patterns were evaluated. Results: There was a correlation between cranial base and maxillomandibular growth patterns. Positive relationships were found between the occlusal plane, Incisor mandibular plane angle, mandibular plane, positioning of pogonion and the saddle angle, indicating maxillary growth patterns. Negative relationships were found between SNA, SNB, maxillary incisor angle and saddle angle. Positive relationships were found between the ratio of the anterior and posterior cranium, positioning of pogonion and the percentage of cranial depth indicating mandibular growth patterns. Negative relationships were found between the occlusal plane, maxillary incisor angle, mandibular plane, mandibular angle and cranial depth. Conclusion: Cranial base and maxillofacial growth patterns were correlated and the classification should be adjusted before orthognathic surgery.

  • The purpose of this study is to report on five cases treated with bone graft using recombinant human bone morphogenetic protein-2 (rhBMP-2) on jaw defects after cyst enucleation. We performed bone graft with BMP (rhBMP-2+${\beta}$-tricalcium phosphate/hydroxyapatite) wrapped with a collagen sponge on jaw defects after cyst enucleation. Postoperative panoramic radiographs were taken periodically. After 1 to 12 months, bone remodeling was observed in the jaw defect area. In our cases, there were few signs or symptoms of recurrence of the cyst during the follow-up period.

  • Objectives: The mandible and other parts of the maxillofacial region suffer significant morbid injuries following road traffic accidents. Our study gives epidemiological description of mandibular fractures in Ghana and also evaluates the relevance of closed reduction and indirect fixation for managing mandibular fractures in low-resource health facilities in low-income countries like Ghana. Patients and Methods: This is a retrospective study involving 268 patients who reported to the Department of Oral and Maxillofacial Surgery of the Sunyani Regional Hospital with mandibular fractures from January 2010 to December 2019. Patient medical records were assessed for information on age, sex, fracture etiology, anatomic location of fracture, time of day of road traffic accident, and other associated injuries. Results: A total of 268 patients were included in this study (males, 216 [80.6%]; females, 52 [19.4%]). Motor vehicular accident (MVA) was the leading cause of mandibular fractures (202 injuries, 75.4%). Other etiologies included assault (39, 14.6%), gunshot (13, 4.9%), falls (12, 4.5%), and industrial accidents (2, 0.7%). Of the 161 male cases caused by MVA, 121 (75.2%) occurred at night and in the evening while the remaining 40 (24.8%) occurred in the morning and afternoon. Among all managed 222 patients, 212 (79.1%) were treated with closed reduction and indirect fixation technique while 10 (3.7%) were treated with open reduction and direct fixation. Conclusion: Closed reduction with indirect fixation could successfully be used to manage mandibular fractures in low resourced health facilities, especially in low-income countries. The poor lightening system on roads in Ghana is a major contributory factor to motor vehicular accidents.

  • This case report presents a case that underwent three-piece segmental maxillary osteotomy and sagittal split ramus osteotomy on a patient with severe facial asymmetry accompanied by maxillary prognathism, severe left scissor bite, and chin point deviation. The resulting facial appearance and occlusion were improved, thereby three-piece segmental maxillary osteotomy is regarded effective methed in treating severe facial asymmetry.

  • Osteoblastoma is a rare tumor of bone representing less than 1% of all tumors of the maxillofacial region. This is a neoplasm of bone characterized by a proliferation of osteoblasts forming bone trabeculae. Because the clinical feature of benign osteoblastoma is nonspecific and osteoblastoma has a pleomorphic histologic appearance, the differential diagnosis is difficult problem. We studies the case records 3 new patients with osteoblastoma. We discussed the case from clinical, radiologic, and histologic feature for differential diagnosis. Three cases from our clinic is reported and analized with previously described cases.

  • Keratocystic odontogenic tumor (KCOT) is a benign cystic intraosseous tumor of odontogenic origin. An infection of a KCOT is not common because KCOT is a benign developmental neoplasm. Moreover, a severe deep neck space infection with compromised airway caused by infected KCOT is rare. This report presents a 60-year-old male patient with a severe deep neck space infection related to an infected KCOT due to cortical bone perforation and rupture of the exudate. Treatment of the deep neck space infection and KCOT are reported.
