최근 디지털 인상채득 시스템이 개발되면서 이를 기존의 CAD/CAM 시스템과 접목한 인레이, 온레이, 크라운이나 간단한 계속가공의치 등의 고정성 보철물의 제작이 활발히 소개되고 있다. 그러나 임플란트 보철에서는 주로 기존의 아날로그식 인상채득 후 이를 스캔하여 제작하는 방법이 사용되어 왔으나, 구강 내 디지털 스캔한 데이터를 이용하여 나사형 보철물을 제작하는 술식은 아직 활발히 이루어지지 않았다. 이에 본 증례보고에서는 6명의 환자를 대상으로 구강 내 스캐너인 iTero를 사용하여 디지털 스캔을 시행한 후 그중 다섯명은 맞춤형 지대주와 시멘트 합착 후 나사형 임플란트 보철물(screw-retained implant prosthesis after cementation, or SCRP)을 제작하였고, 임상적으로 기능과 심미적인 측면으로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다. Fixed dental prostheses such as inlay, onlay, crown, and bridge fabricated by CAD/CAM technique combined with digital impressions is getting popular due to the recent rapid progress of digital impression taking system. For the scope of implant prosthesis, however, digital intra-oral scan hasn’t been actively utilized for the fabrication of superstructures. In this case report, 6 cases of titanium-milled custom abutment based on the iTero intra-oral scan data were introduced, five of them were restored with screw-type prosthesis after cementation (SCRP) and the clinical results were satisfactory on restoring the function and esthetics.

구강 스캐너와 CAD/CAM 기술로 인해 컴퓨터로 제작하는 방식이 활발히 보급된 고정식 보철 증례와는 달리, 의치를 디지털 방식으로 제작하는 데에는 아직 한계가 많다. 촉각을 느낄 수 있는 입력 장비와 전자 서베잉의 개념, 그리고 쾌속 조형법의 적용으로 인해 국소의치를 디지털로 제작할 수 있는 솔루션이 최근 소개되고 있다. 본 증례보고에서는 이러한 국소의치의 디지털 솔루션을 이용하여 총 다섯 명의 환자에서 서베이드 금관 및 국소의치를 제작하였다. 인상 과정상의 문제로 모형과 실제 치아 사이의 형태적 차이가 있었던 경우를 제외하고는 국소의치의 적합도는 우수했으며, 장착 후 안정성과 착탈 시의 유지력 또한 임상에서 적용하는 데에 문제가 없었다. There are still many limitations on fabricating dentures using digital method while computerized production of fixed prostheses utilizing intraoral scanner and CAD/CAM technology has propagated rapidly. Recently the digital solution of fabricating removable partial denture by applying haptic input device, electronic surveying, and rapid prototyping was introduced. In this case presentation, five patients were treated with surveyed crown and removable partial dentures by this digital solution. Fit of dentures was excellent except for one case which showed morphological difference between the actual teeth and that of master cast by the erroneous impression process. There also was not any problem of stability and retention after adaptation in the clinical setting.

A. The necessity and purpose of the study Since 1960s the number of university and college students has increased due to the rapid industrial development which requires more technical and intellectual persons. Also the upward spreading effects of education with generalization of secondary education have increased the social demands of liberal education, which expedite university students' diversity and heterogeneity. Therefore, the problems of students are no longer those of school authorities, but expand into social and national problems. Recently most of university in Korea have put more emphasis on the rearrangement and reinforcement of Student Guidance System. Especially, in case of Jeju National University, taking into considerations the special geographical conditions far away from the Korean mainland, and transitional stage on which JNU was promoted to national full-university status, along with the unification of campuses, the more careful interests and efforts are required for student guidance. This study was conducted with a view to providing the opportunities of educational and social specialization of student guidance. The following are the purpose of this study: 1) To set up directions for student guidance which can carry out the role and function of the university. 2) To consider, in the aspect of education, the main factors which influence the problems of university students. 3) To find out the difference between the problems of students' demand and abilty and realities of guidance, by comparing and analyzing present guidance realities between universities. 4) To offer improvement directions for efficient student guidances. B. The scope and contents of the study 1) The problem of student guidance in view of the purpose and function of a university. 2) The fundamental viewpoint of guidance in university 3) A theoretical investigation for efficient student guidance 4) A root cause of student problems 5) The present condition and problems of student guidance 6) Improvement directions for guidance C. The method of the study 1) To analyze the domestic data as well as foreign data 2) To analyze the questionnaire 3) To analyze the results of guidance through the actual result reports of student guidance 4) To analyze various data of student guidance 5) To represent by percentage(%) the realities and problems of student guidance D. The problematic factors of student guidance in the light of purpose and function of a university 1) The original purpose and functions of university are the acquisition of knowledge the transmission of knowledge, and application of knowledge. They are based on the wholemen community of intellectuals in which research, education, and service are determined to be prime mission, but hasn't well been fulfilled because of the present special situations of Korea. 2) In the expectations of university's roles, it is becoming important to harmonize the real desire of administrative officials, intellectual desire of professors, and idealistic of students with each other. 3) A university's research function of creating academic atmosphere is very unsatisfactory. 4) The relationship between professors and students, and even among students hasn't well progressed because of excessive solicitude of omission by graduation quota system as well as full classes. And cultural education is not conducting effectively because it is very fragmentary and formal. 5) The chaos is being produced about the establishment of concept of community service given to university education, the ways and limitations of participation in society and actual world. E. The viewpoint of student guidance The contents and methods of student guidance are decided according to the view of students to be the subject of guidance. In the reformative viewpoint of student guidance by educative instruction methods, main method of guidance are authority, blind obediance, cramming, subjectivity, control, rectification. From the educative viewpoint of student guidance, self-direction can be possible by means of students' interest, desire and ability. Future student guidance must be conducted to develop their potentiality and natural ability of growth without external force or blind gramming. F. Following theoretical investigation were enforced in order to establish effective directions for student guidance. 1) The concept and purpose of the orientation for freshmen and its basic policy and contents 2) The necessity and contents of department arrangement guidance 3) The practice of alloted academic adviser system 4) The educational functions, necessity, and meaning of campus extracurricular activity 5) The role and function of student government(SNDC) 6) The welfare and scholarship system for students G. As a result of a selection of root causes of student problems from the introspection, the following were important order of immediate and expected problems 1405 freshmen; 1. Studies Problem(40.3%) 2. Course problem(36.4%) 3. Economic life problem(36.9%) 4. Social fitness Problem(26.7%) 5. Health Problem(16.0%) The investigation consequence for sophomore and junior are following; 1. A course Problem(35.2%) 2. Economic life problem(35.4%) 3. Human relation problem between professor and student(35.2%), and a good use problem of spare time(35.2%) 4. Studies problem(26.4%) H. The problems were revealed by a statistics which were investigated and analyzed realities of student guidance as follows, respectively: 1. In the orientation for fresh, it is emphatic to give only a information, the program of a important purpose in an orientation that are helpful to initiation of university life with a safety emotionally by withdrawing from strain from strange environment is making light of. 2. In the guidance of a department choice, department allocation by a record is making without giving a chance searching for self-characteristic like aptitude or hobbies, the guidance plan and materials of objectivity are not prepared, and the chance choosing carefully comes very short of. 3. In the management of partial charge professors system, the relation position between professor and student is very formal because, as a matter of fact, it is meaningfulness to guide students from a professor is responsible for guidance of so many students, director of professors are in want of the whole recognition about guidance contents. 4. Though the circle activities are very important as an educational function, a director professors of a circle has charge of guidance for so many students, the activities without purpose consciousness are unfolding, the activities with interest and recreation mainly are rich in, and the activities for enlightenment sound activity model which gets a value experience are situation insufficiency itself. 5. In the activities and management of Student Body, he is not accomplishing plan and function by nature, the activities and management individual and new are very lack owing to emphasis of events centre and actual results centre. And the appearance of making heteronomy now that he is not also chose relation to the circles in SNDC is more and more deepening. 6. The lower organization taking charge of students guidance specially in managent of the students guidance institute are in need, the number of specialists are for want of, it is just so formal to run the students guidance institute because the institute's finance is in very poverty, its originally functions are not accomplishing due to the consultation mood in consultation room is stiff. 7. Our university lacks in research facilities and mental incentive with regard to student welfare function. I. I am directing the way of student guidance for withdrawing from and getting rid of the problems revealing, concerning the students guidance to the best of his ability by the realities of students problems as follows; First, the investigation and research activities and assistance understanding and helping students have to provide in the side of prevention of problems by understanding university students' nature consciousness and characteristic regularly. Second, students' spontaneous participation, the development of interesting and useful programmes, and faculty members' active supports & guidance should be given to obtain effective result of fresh's orientation. Third, school authorities should provide freshmen with opportunity to judge their aptitudes from the time of entrance by holding orientation several times, and by offering detailed informations on the department selection. Fourth, The academic & human relations between professors and students should be maintained through proper enforcement of alloted academic professor system. Fifth, every circle and club should established proper and patent objectivities of activity, and try, to create and introduce useful and interesting programmes in order to promote an educational function of each circle and club. Sixth, in order to eleminate the gap between students and Students Government, students should take deep interests in Student Body's activity, while Student Body should develop academic and literary activity to promote students research activities. Seventh, in order to promote the function of Student Guidance Institute, there should be secured expert staff for smooth counselling, investigation and employment guide as well as financial and administrative support of school authorities. Finally, university authorities should organize several institute such as student welfare committee(institute) so that they might grasp what student opinions & desire are and make students lead comfortable campus lives.
