목적: 연구의 목적은 동일한 지대치에서 각각 모델스캔 방법과 구강 내 스캔 방법으로 제작된 지르코니아 보철물의 변연 및 내면적합도를 비교하는 것이다. 재료 및 방법: 발거된 사람의 하악 제1대구치 20개에 대해 지르코니아 보철물을 위한 지대치 형성이 이루어졌다. 첫 번째 그룹에서는 모델 스캔법으로 10개의 지대치를 스캔하였고, 두 번째 그룹에서는 나머지 10개에 대해 구강 내 스캔법을 사용하였다. 각각의 데이터들은 소프트웨어 시스템으로 전송되었고 Ceramill CAD/CAM system을 이용하여 20개의 지르코니아 보철물을 제작하였다. 먼저 weight technique을 사용하여 내면 적합도를 평가하였다. 다음으로 replica technique에서는 광학현미경을 통해 변연 적합도를 평가하였다. 통계처리는 일원배치분산분석을 이용하였다. 결과: 먼저 weight technique에서 모델 스캔법으로 제작한 그룹에서 구강 내 스캔법으로 제작한 그룹에 비해 평균적인 무게 값이 낮게 나타났고, 이는 유의성이 있었다(P < .05). 또한, replica technique에서도 측정된 5개의 영역 모두에서 구강 내 스캔법으로 제작한 그룹에 비해 모델 스캔법으로 제작한 그룹에서 변연 및 내면의 gap에 대한 거리 값이 유의하게 낮게 나타났다(P < .05). 결론: 두 그룹의 방법으로 제작한 지르코니아 보철물은 모두 임상적으로 받아들여질 만한 변연 및 내면 적합성을 보였다. 하지만 모델 스캔법으로 제작한 그룹에서 구강 내 스캔법으로 제작한 그룹에 비해 높은 변연 및 내면 적합성을 보였다. Purpose: This research was conducted to compare the marginal and internal fit of zirconia prostheses fabricated with the model scan method and the intraoral scan method. Materials and methods: In this study, 20 extracted human mandibular first molar was used in the preparation of abutment tooth for the fabrication of zirconia prostheses. In the first group, the model scan method was applied on 10 prepared teeth. In the other group, the intraoral scan method was used on other 10 prepared teeth. Datum of both groups were transmitted to the software system. Afterwards, 20 zirconia prostheses were fabricated using the Ceramill system. Weight technique was used to evaluate the internal gap of the zirconia prostheses. In the Replica technique, marginal gap of the zirconia prostheses were analyzed by optical microscopy. Statistical analysis was based on one-way ANOVA. Results: Model scan group showed lower average weight than intraoral scan group when weight technique was applied, which has significance (P < .05). Also, model scan group showed significantly lower figures in all 5 measurements of replica technique than intraoral scan group (P < .05). Conclusion: Zirconia prostheses of both groups demonstrated clinically acceptable margin and internal fit. However, model scanned zirconia prostheses showed higher marginal and internal fit than intraoral scanned crowns.

구강암의 발생 시, 구순의 결손과 방사선치료에 의한 치주조직과 치경부우식증 등의 문제가 발생할 수 있다. ADI (Association of dental implantology)에 의하면 상 하악골에 대한 방사선치료가 최근에 시행되었을 경우 임플란트를 식립하는 것은 상대적 비적응증이 된다. 대부분의 경우 임플란트를 이용한 보철물의 제작이 어렵고 의치를 사용한 수복이 이루어지게 된다. 특히, 구강암 수술로 인한 구순결손은 의치의 유지에 심각한 영향을 주게 된다. 본 증례는 상순암을 가진 환자로 일차적으로 절제술을 시행하고, 이차적으로 방사선 치료가 정기적으로 이루어진 결과, 환자의 상악 치아들은 순차적으로 자연 발치되었고, 하악은 매우 불량한 치주상태를 나타내었다. 상악은 총의치에 의치접착제를 적용하여 구순결손에 의한 의치의 유지력 저하를 극복하였고, 하악에서는friction pin을 이용한 하악이중관의치가 2년 동안 성공적으로 사용되었다. When oral cancer is occured, one may experience problems such as lip defect, necrosis of periodontal tissue and cervical caries caused by radiotherapy. According to ADI (Association of dental implantology), recent radiotherapy on jaw bone could be a relative contraindication of implant treatment. Due to this controversy, in most cases, treatment is done with removable dentures rather than implants. Especially, lip defect caused by an oral cancer operation have a serious repercussion on the retention of the denture. In this case report, patient with upper lip cancer had undergone resection primarily and secondary radiotherapy was done periodically. As a result, upper teeth of patient were extracted gradually and lower teeth showed very poor periodontal status. Therefore, Polident$^{(R)}$ denture adhesive cream (GlaxoSmithKline, London, England) was applied on maxillary complete denture to overcome reduced retention due to the lip defect and double crown RPD with friction pin was applied on the mandible successfully for two years.

This study was conducted as a research study to find out the relationship between elementary school teachers’ perception of non-disabled students’ experience of contact with students with disabilities and providing emotional distance on negative attitude changes toward students with disabilities. 6 questions of contact experience, 6 questions of emotional distance, and 6 questions of negative attitude change were developed. The data of 336 elementary school teachers were analyzed. The research results are as follows. First, it was found that non-disabled students’ experiences of contact with students with disabilities did not affect the change in their negative attitude toward students with disabilities. Second, it was found that elementary school students’ experiences of contact with students with disabilities had a positive effect on emotional distance. Third, it was found that when elementary school students’ experiences of contact with students with disabilities mediate emotional distance, they have a statistical effect on changes in their negative attitude toward students with disabilities. In conclusion, this study suggests that the experience of contacting students with disabilities in elementary school students should be considered as a condition to provide a positive effect on the change of negative attitude toward students with disabilities, and a way to feel the joy and reward of experience should be considered together. 본 연구는 초등학교 교사가 인식하는 비장애학생의 장애학생과의 접촉 경험 및 정서적 거리감 제공이 부정적 태도 변화에 미치는 관계를 알아보기 위하여 조사연구로 수행되었다. 접촉 경험 6문항, 정서적 거리감 6문항, 그리고 부정적 태도 변화 6문항을 개발하였다. 초등학교 교사 336명의 자료를 분석하였다. 연구 결과는 다음과 같다. 첫째, 비장애학생의 장애학생에 대한 접촉 경험은 장애학생에 대한 부정적 태도 변화에 영향을 미치지 않는 것으로 나타났다. 둘째, 초등학생의 장애학생과의 접촉 경험은 정서적 거리감에 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 초등학생의 장애학생에 대한 접촉 경험이 정서적 거리감을 매개할 때, 장애학생에 대한 부정적 태도 변화에 통계적으로 영향을 미치는 것으로 나타났다. 결론적으로 본 연구에서는 초등학생의 장애학생에 대한 접촉 경험은 장애학생에 대한 부정적 태도 변화에 긍정적 영향을 제공하기 위한 조건으로 경험의 즐거움과 보람을 느낄 방안이 함께 고려되어야 함을 제안하고 있다.
