Sedation is often indicated for the relief of anxiety for outpatient oral surgery. In combination with local anesthesia, it is safe and effective method of treatment. However, it is not always effective in allowing the physician to complete the planned oral surgery procedure. On occasion, a procedure is left unfinished due to patient combativeness and discomfort and hypertension in spite of increase in sedative doses. Episodic increases in blood pressure were most commonly caused by light anesthesia or sedation and by the patient's experience of pain during treatment. Female patient was 42 years old. blood pressure is 150/90 mmHg. Extraction and implant surgery was done under IV sedation. During seadtion, her blood pressure was increased (200/100 mmHg). Surgery was stopped. She was done monitoring blood pressure. The blood pressure was decreased to 130/90 mmHg. Sedation was failed due to significant hypertension. Blood pressure is seldom increased during sedation but we should evaluate the patient's medical history and know guideline for hypertension crisis.

본 연구의 목적은 정부의 주도하에 진행되고 있는 시니어 대상 창업교육과정 참가자들의 교육 전‧후 사회네트워크 분석을 통해 네트워크 활성화를 위한 창업교육 프로그램의 필요성을 제시함에 있다. 본 연구는 경남 G대학에서 주관한 시니어기술창업교육을 수료한 대상자 60명을 선발하여 교육 전‧후 친밀도를 분석하고, 참여자들간의 전략적 제휴 정도를 포함하는 관계변화를 분석하였다. 경남 G대학의 시니어기술창업교육은 기술교육과 더불어 참여자 네트워크 형성에 초점을 두어 액션러닝을 기반한 교육을 기획, 진행한 특징을 가지고 있다. 본 연구는 대상자들 간의 관계에 대해 설문(있다/없다)을 진행하고, 데이터를 수집 및 정제하여 사회네트워크 중심성을 분석하였다. 네트워크 중심성은 네트워크 내 영향력을 분석할 수 있는 요소이다. 중심성이 높다는 것은 네트워크 내에서 업무와 관련한 영향력과 명성도가 높다는 것과 의사결정 과정에 중요한 영향을 미친다는 것을 의미한다. 구체적으로 본 연구는 첫째, 사회네트워크 분석을 통해 교육전과 교육후 친밀도 기반 네트워크 변화를 분석하고 통계적으로 그 의미를 해석하였다. 둘째, 창업교육 수료생이라는 대상의 특성을 고려하여 창업단계에서 네트워크 내의 참여자 간에 이루 어질 수 있는 전략적 제휴 정도를 분석하였다. 셋째, 전략적 제휴를 기반으로 분석한 자료에서 네트워크 중심성이 높은 대상자들을 추출하여 인터뷰를 진행하였다. 인터뷰를 통해 추가적으로 확보한 구체적 사례로 서베이 연구를 보완하였다. 연구 결과, 친밀도 기반 네트워크의 변화는 통계적으로 유의미했으며, 인터뷰 결과, 농업기반 창업의 초기단계에서 이루어질 수 있는 전략적 제휴 사례를 확인할 수 있었다. 전략적 제휴 네트워크에서 중심성이 높은 참여자들은 모두 경남 G대학의 시니어기술창업스쿨 교육과정 중 형성된 네트워크를 창업단계에서 절대적으로 필요한 무형자산으로 생각할 뿐만 아니라 네트워크의 중요성을 인지하고 있었다. 본 연구결과는 시니어를 위한 창업교육프로그램 설계와 창업활성화를 위한 전략의 설계 방향으로 유용하게 활용될 것으로 기대한다. 마지막으로 본 연구의 한계점과 향후 연구방향을 논의하였다. The purpose of this study is to present the necessity of entrepreneurship education program for network activation through analyzing pre - and post - social networks of the participants in senior technology start-up education. We selected 60 people who completed the senior technology start-up education which was supervised at Gyeongnam G university, analyzing not only density (intimacy) before and after education but also the change in the relationship including the degree of strategic alliances among the participants. Senior start-up education at Gyeongnam G University is characterized by action learning focusing on the formation of network among participants as well as technical education. We conducted the questionnaires on the relationship with the subjects’ answers of yes or no, gathered and refined the data, analyzing the social network centrality. Network centrality measures the degree of influence in the network. The high centrality means that it has a significant influence on the decision making process, and that the influence and reputation associated with work in the network are also high. Specifically, we first analyzed the change of intimacy-based network before and after education through social network analysis. Secondly, we analyzed the degree of strategic partnership (alliances) that can be carried out among participants in the network at the start-up stage. Thirdly, in the data analyzed on the strategic alliance, we selected to interview the people of high network centrality. We complemented the analyses and results of survey data with the concrete examples of interviews. As the result of survey data analyses, changes in intimacy-based network were statistically significant, while we were able to confirm the cases of strategic alliances that can be done in the early stages of farm foundation by the interviews. All participants of high centrality in the strategic alliances network regarded the network formed in the senior technology start-up education program as an absolutely necessary intangible asset at the inception stage, recognizing the importance of the network. The results would imply the desirable directions for designing the start-up education program for seniors as well as the strategy of activating start-ups. Lastly, we discussed the limitations and future research directions.

Objectives: The aim of the present review was to evaluate survival rate and various factors associated with survival of osseointegrated implants. Patients and methods: The clinical comparisons were performed to evaluate survival rate of 794 endosseous implants that had been inserted between 2004 through 2008 in relation to sex and age of patients, position of implant, implant system and surface characteristics, length and diameter of implant, and bone graft technique. Results: The survival rate of implant was 94.3% in posterior area of maxilla and 98.6% in posterior area of mandible by position of implant, a statistically significant difference. As to diameter of implant, survival rate was 98.4% between the 4.0 and 4.5 mm and 75.0% in larger than 5.0 mm, that was statistically significant difference. There was a statistically significant difference regard to bone graft and surgical technique. The implant survival rate was 89.0% in a placement site which performed sinus lifting, and in case of implant placement with guided bone regeneration technique and without bone grafting was 97.6% and 100% each. Conclusion: According to these findings, this study establishes a relationship between survival rate of implant and position, surface characteristics, diameter of implant and bone graft technique.

Epidermoid cyst is a cystic form of teratoma and believed to be derived from trapped embryonic cells along the lines of embryonic closure. A 28-year-old woman presented with a painless swelling over the left mandibular area. On panoramic view, the mandible revealed a $5.5{\times}2.0\;cm^2$ multilocular radiolucent lesion of the left mandibular body and a computed tomography scan showed expansion of both the buccal and lingual plates in the same area. Microscopy found stratified squamous epithelium of the cystic wall and cystic contents of keratinized material. The histological diagnosis wasan epidermoid cyst. The most common location of epidermoid cyst at the head and neck is in the orbit (47%), followed by the mouth floor (23%) and the cervical area (9~24%), but in the jaw bone, it is considered very infrequent. We report the uncommon epidermoid cyst in the mandibular body that had a good healing outcome after treatment with a conservative marsupialization during the 40 months follow-up.

Purpose: The purpose of this study was to evaluate marginal bone loss of the alveolar crest on implants with or without guided bone regeneration and variables that have influenced. Methods: The clinical evaluation were performed for survival rate and marginal bone loss of 161 endosseous implants installed with guided bone regeneration (GBR) in 83 patients from September 2009 to October 2010 in relation to sex and age of patients, position of implant, implant system, length and diameter of implant. Study group (n=42) implant with GBR procedure, control group (n=41) implant without GBR technique. Simultaneous GBR approach using resorbable membranes combined with autogenous bone graft or freeze-dried bone allograft or combination. Radiographic examinations were conducted at healing abutment connection and latest visit. Marginal bone level was measured. Results: Mean marginal bone loss was 0.73 mm in study group, 0.63 mm in control group. Implants in maxillary anterior area (1.21 mm) were statistically significant in study group (P<0.05), maxillary posterior area (0.81 mm) in control group (P<0.05). Mean marginal bone loss 1.47 mm for implants with diameter 3.4 mm, 0.83 mm for implants of control group with diameter 4.0 mm (P<0.05). Some graft materials showed an increased marginal bone loss but no statistically significant influence of sex, implant type or length. Conclusion: According to these findings, this study demonstrated the amount of marginal bone loss around implant has maintained a relative stable during follow-up periods. We conclude that implants with GBR had similar survival rate and crestal bone level compared with implants in native bone.

Objectives: This study was performed to evaluate course of the inferior alveolar canal in the mandibular ramus and to find safety zone when ramal bone is harvested. Patients and Methods: From January, 2009 to February, 2009, the 20 patients who visited in the Department of Oral and Maxillofacial Surgery, Sanbon Dental Hospital. Wonkwang University and the Conebeam CT was taken of various chief complaints, were selected. The patients who had left and right mandibular first molar and incisor missing, jaw fracture and bone pathology were excluded. The R point was defined as the point which occlusal plane was crossed to the mandibular anterior ramus(external oblique ridge). In the cross-sectional coronal and axial views, the inferior alveolar canal position to the R point, buccal bone width(BW), alveolar crest distance(ACD), distance from alveolar crest to occlusal plane(COD) and inferior alveolar canal to sagittal plane(CS) were measured and horizontal distance(HD), vertical distance(VD) and nearest distance(ND) were measured. Results: The inferior alveolar canal is located $6.19{\pm}1.21\;mm$ from the R point. Horizontal distance from the R point were $13.07{\pm}2.45\;mm$, vertical distance from the R point were $14.24{\pm}2.41\;mm$ and nearest distance from the R point were $10.12{\pm}1.76\;mm$. The course of the inferior alveolar canal was positioned within $0.61{\pm}0.68\;mm$. The distance from external buccal bone to the inferior alveolar canal was increased from the R point anteriorly. Conclusions: It is considered that the mandibular ramus from the R point to 10 mm anteriorly can be harvested safely at ramal bone grafting.

Ameloblastoma is the most common aggressive benign odontogenic tumor of the jaws. Because of slow growth and tendency to local invasion of bone and soft tissue, high rates of recurrence are common. The treatment for ameloblastoma is still controversial and poses some special problems in children. Because of growth of the jaw and the different incidence, prognosis of the tumor make the surgical consideration different from adults. Radical resection cause facial deformity, jaw abnormal movement and masticatory disturbance especially to child and adolescents. So conservative treatment as enucleation, curettage is acceptable initial treatment of ameloblastoma in children who can be followed up in a precise, detailed manner. This report describes a case of unilocular plexiform ameloblastoma treated by enucleation and curettage followed by marsupialization.

Uni- or bilateral mandibular hypoplasia can be associated with various syndromes or is acquired after early traumatic or inflammatory disease in the temporomandibular joint(TMJ). Early treatment is necessary to avoid consequent impairment of midfacial growth. The standard treatment of these malformations consists of the application of bone grafts which can lead to unpredictable growth, but the new procedure of bone lengthening which was presented by McCarthy et al. represents a limited surgical intervention and therefore open up a new perspective of treatment, especially in younger children with severe deformities. Patients with hemifacial microsomia and facial asymmetry have a vertically short maxilla, a tilted occlusal plane, and a short mandible. A 14-years-old boy with facial asymmetry, who was fractured on both condyle and mandibular symphysis before 8 years ago, was treated by mandibular ramus lengthening, symphysial widening and surgically assisted rapid palatal expansion with corticotomy. After allowing 1 week for the healing of the periosteum, the distraction was performed at the rate of 0.5-1.0mm per day for 7 days on maxilla and 14 days on mandible. The device was maintained on maxilla and mandible for 12 weeks following distraction. The difference in ramus and mandibular transverse deficiency were corrected and facial asymmetry was improved with complex distraction osteogenesis.
