In this case report, immediate loading of an implant-supported single-tooth prosthesis through complete digital workflow. A patient presented for restoration of missing a single tooth in the mandibular first molar. The digital impression was made with intraoral scanner and implant was placed using surgical guide pre-fabricated with pre-operative computed tomography (CT) and scan data. After 1 week later, prefabricated customized abutment and provisional restoration were connected for immediate loading. After 8 weeks later, abutment level impression was taken by intraoral scanner. At 3 months later from implant installation, monolithic zirconia crown were fabricated. This clinical report presents satisfying result in accuracy and patient satisfaction. A completely modeless digital procedure met expectations regarding precision, esthetics, and functionality.

It is essential to record maxillomandibular relationship accurately for the harmony of esthetic and function in complete denture. Gothic arch tracing visually demonstrates the movement of the mandible, and is useful to establish accurate and reproducible centric relation. Proper retention and stability of complete denture in patients with severe alveolar bone resorption is difficult to attain. In such case, the closed mouth impression technique might be recommended. The denture border and impression are determined by patient's physiologic movement in the closed mouth impression technique. And, denture peripheral border is entirely closed with oral mucous membrane. This report presents satisfactory complete denture restoration using closed mouth impression technique and gothic arch tracing in patients with mandibular condyle fracture and severe absorption of mandibular alveolar ridge.

In patients with myasthenia gravis, it is difficult to manufacture and maintain dentures because the muscles and nervous system in the oral cavity are not properly adjusted. In addition, excessively extended or thick dentures may cause muscle weakness by stimulating the muscles, so dentures should be manufactured in consideration of this. In this case, a denture was fabricated using the closed mouth technique in a patient with myasthenia gravis with mouth opening limitation. Using the closed mouth technique, the patient's masticatory pressure and muscle movements were reproduced and denture with good retention were manufactured.

It is very difficult to achieve denture support, stability and retention in single-maxillary complete denture patients with flabby tissue. A 57-year-old male patient was uncomfortable with the existing denture and wanted treatment. The reduction of flabby tissue was confirmed using the treatment denture. Non-pressure impression was obtained using an intraoral scanner during the definitive denture process. This is reported because the resulting denture improved when observing the retention, support and stability of the denture during occlusion.

인터넷 환경의 변화와 관련 제반 기술의 발달로 인하여, 이전과는 달리 콘텐츠의 제작, 활용에 있어서 높은 사용자 참여도를 보여주고 있다. 이러한 변화는 여가 활동의 증가와 엔터테인먼트를 추구하는 인터넷 사용자의 목적과 맞물려 UCC(User Created Contents)가 중요한 요소로 부각되게 되었다. 이미 온라인과 오프라인상에서 사용자가 UCC를 제작할 수 있는 장비들과 다양한 도구들이 보편화 되어있다. 그러나 UCC와 관련된 프로그램 및 장비들의 기능과 플랫폼이 복잡해짐에 따라 사용자가 콘텐츠 제작에 있어 어려움을 겪고 있는 실정이다. 따라서 콘텐츠의 제작과 활용 측면에서 기능과 서비스를 자연스럽게 사용할 수 있도록 하는 통합적인 환경 제안과 발전 방향을 모색하는 것을 연구의 목적으로 삼는다. 본 연구의 방법으로는 콘텐츠를 제작하는 사용자를 대상으로 한 환경 조사 그리고 포커스 그룹 정성 조사를 통하여 현재 UCC제작 환경의 문제점을 도출하였다. 이를 기반으로 사용자의 니즈를 충족시키면서도 사용자 중심적인 통합적 UCC 제작 도구와 개발을 위한 가이드 라인을 제시한다.

멀티미디어의 정보 전달 기능과 인상에 의한 교육 기능이 강력함에 따라 많은 멀티미디어 교육용 시스템이 개발되었으나 대부분의 경우 내용이 빈약하거나 시나리오가 고정되어 있어서 다양한 상황을 연출하지 못하고 단편적인 내용 전개에만 그치고 있으며 학생의 참여가 미흡한 일방적인 지식 전달에 머무르고 있는 설정이다. 이것은 멀티미디어 데이터는 많으나 데이터를 상연할 시나리오가 제작자의 의도대로만 전개되고 사용자의 행동에 따라 다양한 상황으로 전개할 수 있는 여건이 마련되지 않았기 때문이다. 따라서 본 논문에서는 데이터베이스와 멀티미디어 스크립트를 이용하여 필요한 데이터만 갖추어진 제작자의 창의력에 따라 다양한 교육 내용을 저작할 수 있고, 실행 중에 사용자가 다른 상황으로 전개할 수 있는 스크립트와 시뮬레이터를 제안한다.

소금은 공기나 물과 마찬가지로 사람이 생명을 유지하는 데에 없어서는 안 될 중요한 물질이다. 즉 체액의 삼투압의 균형유지, 신경이나 근육의 활동조절 등을 통하여 생명유지에 중요한 역할을 수행한다. 즉 영양분을 운반하거나 신진 대사를 하거나 노폐물 등 물질이 이동될 때에는 삼투압이 근 구실을 하게 되는데 소금은 이와 같은 체액의 삼투압이 균형을 유지할 수 있도록 하는 것이다. 이외에 소금은 위액의 염산이 되어 살균 작용이나 소화작용을 도와준다. 또한 소금은 간접적으로 적혈구의 생성을 도우며 발한 작용을 통하여 체온의 적절한 유지 기능도 가지고 있다. 이외에 최근 여러 사람이 이용하고 있는 죽염의 기능성 여부에 대하여도 과학적인 규명이 필요한 것으로 보인다.

When full denture is being fabricated, pronounciation, recovery of aesthetics of function and mastificatory function should be satisfies for patients. To satisfy for the function of denture, following is the difference between this new way of fabricating and formerly one of it. 1. The size of fabricating tooth which is harmony of original oral structure for patients is deaded by manufacturing labial index and artificial tongue. 2. By the use of artificial tongue and labial index, the arranges of artificial tooth is to become harmony of oral structure. 3. Formation of gingival decided functional impression which is used by impression paste, is harmony of oral structure. Therefore, this full denture can be satisfied with pronouncing oral function of recovery of aesthetics as well as mastificatory through physiological movement of oral tissue not disturbed with anything but cooperated drastically. In manufacturing of this full denture, both dentist and dental technician under cooperation need to proceed the work on the base of importance of communication.

In order to produce a stable denture for severe alveolar bone loss area, it is not only important that .0a suitable occlusion is established but also to consider compatibility with the surrounding muscle to form a suitable polished surfaces. Neutral zone is defined as a potential area where the neuromuscular system of the tongue, cheeks and lips is balanced can be determined through the neutral zone impression technique. And if artificial teeth are aligned within the neutral zone and the polished surface follows the anatomical form of the dynamic muscle, higher stability and retention of the denture may be obtained through coordination with the surrounding muscle tissue. This case is being reported since the concept of the neutral zone was applied to a patient with severely atrophic residual alveolar ridge and the result was clinically satisfactory in both function and aesthetics.

Recently with the advance in digital dentistry, the fabrication of dentures using computer-aided design and computer-aided manufacturing (CAD-CAM) is on the rise. The denture designed through a CAD software can be produced in a 3-dimensional manufacturing process. This process includes a subtractive processing method such as milling and an additive processing method such as 3D printing and in which it can be applied efficiently in more complex structures. In this case, complete dentures were fabricated using Stereolithography (SLA)-based 3D printing to shorten the production time and interval of visits in patient with physical disabilities due to cerebral infarction. For definitive impression, the existing interim denture was digitally replicated and used as an individual tray. The definitive impression obtained with polyvinyl siloxane impression material was including information about the inclination and length of the maxillary anterior teeth, vertical dimension, and centric relation. In addition, facial scan data with interim denture was obtained so that it can be used as a reference in determination of the occlusal plane and in arrangement of artificial teeth during laboratory work. Artificial teeth were arranged through a CAD program, and a gingival festooning was performed. The definitive dentures were printed by SLA-based 3D printer using a FDA-approved liquid photocurable resin. The denture showed adequate retention, support, and stability, and results were satisfied functionally and aesthetically.
