The anterior guidance is one of the important factors in prosthodontic treatment of anterior teeth. The lingual surface shape of anterior restorations is so critical that small errors of treatment procedure can cause discomfort of the patient and disharmony of the dentition. If the anterior restorations are achieved harmonious anterior guidance through the fabrication and adjustment of provisional restorations, it is important to accurately reproduce the lingual surface shape of provisional restorations as the final prosthesis. In this case report, it was used the modified Dahl principle and copy-milled technique of computer-aided design/computer-aided manufacturing (CAD/CAM) system for systematic diagnosis and treatment. Therefore, we tried to reconstruct the restoration shape more precisely by setting the appropriate anterior guidance and superimposing the digital image of the abutment teeth and the provisional restorations. Thus, by promoting functional and esthetic recovery, this case report demonstrates satisfying results to both the patients and dentist.

South Korea has recently emerged as one of the leading countries conducting clinical trials. Seoul, for instance, is now ranked at the top of the list among the cities in the world. This paper examines the rapid growth of research involving human subjects in Korea, not just from the economic perspective (e.g., the growth of global pharmaceutical markets and the subsequent increase in the demand for clinical trials), but from the policy perspective (e.g., the government?s drive to support and promote this field as a new industry). The industrialization of clinical trials in Korea has manifested itself in the rise of international Contract Research Organizations (CRO) doing their business in Korea. They are, figuratively speaking, invited to Korea by the government. This paper intends to uncover and discuss the bioethical issues concerning research on human subjects, the issues that tend to be set aside merely as procedural ones like ??workable documents??. To this end, it investigates the practice of clinical trials by collecting hitherto unherad voices from patient-volunteers, physician-researchers, CRO employees, and government officials. This paper also explores the themes of ??ethical variability?? and ??biocapital?? in order to compare and constrast the case in Korea with those in other countries.

Deep blocking of consciousness alone does not prevent a reaction to severe stimuli, and copious amounts of pain medication do not guarantee unconsciousness. Therefore, anesthesia must satisfy both: the loss of consciousness as well as muscle relaxation. Muscle relaxants improve the intra-bronchial intubation, surgical field of vision, and operating conditions, while simultaneously reducing the dose of inhalation or intravenous anesthesia. Muscle relaxants are also very important for breathing management during controlled mechanical ventilation during surgery. Excessive dosage of such muscle relaxants may therefore affect neurological examinations during surgery, but an insufficient dosage will result in movement of the patient during the procedure. Hence, muscle relaxation anesthesia depth and neurophysiological monitoring during surgery are closely related. Using excessive muscle relaxants is disadvantageous, since neurophysiological examinations during surgery could be hindered, and eliminating the effects of complete muscle relaxation after surgery is challenging. In the operation of neurophysiological monitoring during the operation, the anesthesiologist administers muscle relaxant based on what standard, it is hoped that the examination will be performed more smoothly by examining the trends in the world as well as domestic and global trends in maintaining muscle relaxant.

As the increased certainty of osseointegration, new parameters are now being used to assess implant success. Accordingly, patients' and clinicians' high demands and expectation for esthetics have expanded and implant-supported restorations show better esthetic outcomes. The pre-implant treatment planning process, the implant surgical steps and the post-surgery prosthetic process can affect all esthetic outcomes. Prevention of esthetic implant failures can be achieved by appropriate treatment at each stage, considering the 3 factors of alveolar bone, soft tissue, and implants. It is necessary to achieve the esthetic implant prostheses followings: minimal invasive surgery, bone augmentation, ideal 3-dimensional implant position, peri-implant soft tissue management, and provisional restorations to optimize peri-implant soft tissue architecture.

Objectives: The purpose of this study was to evaluate learners' satisfaction with operating Problem-Based Learning (PBL), competency level for dental hygiene, and learners' opinions through a reflection journal by developing a PBL class module and applying it to clinical dental hygiene classes. Methods: The subjects of the study were 31 students in the Clinical Dental Hygiene (oral health management for special patients) course in the second semester of the fourth grade. This study was conducted over the first semester from September to December 2020. The developed PBL learning module was applied for the 15 weeks class, and after all PBL classes were over, the overall satisfaction with the class and the change in student competency level was evaluated. Results: The overall satisfaction of learners with PBL was high, and the level of self-competence also increased compared to before class. In addition, the top three topics (Competencies learned through PBL, humanistic and sociological elements learned through PBL, and obstacles in the PBL) were derived through the reflection journal after PBL learning activities. Conclusions: It was confirmed that the PBL learning module developed in this study is a class that enables students to identify problems and solve them integrally and drives the improvement of humanities and sociological competencies.

This case report introduces a 74-year-old male patient who visited retention deficiency of the mandibular implant overdenture, which was fabricated 20 years ago. When the existing dentures were used, the vertical dimension was reduced, the maxillary complete denture lacked lip support and retention, and the mandibular overdenture lacked clip retention due to damage to the bar attachment. After removing the damaged bar attachment, it was replaced with a ball attachment, and impressions were taken using the DENTCA^TM Tray and then the vertical dimension was measured. The gothic arch tracing was performed to record the centric relation. Obtained impressions were scanned and the shape of final dentures was designed using software and try-in dentures were fabricated using 3D printer. After evaluating the occlusal plane, occlusal relationship, facial shape, and pronunciation using the try-in dentures, the bite registration was recorded, and the final denture was manufactured based on this. The inner surface of the denture was adjusted and bilateral balanced occlusion was formed, and the housing was connected to the mandibular denture by a direct method. This case reports have shown satisfactory resultin recovering improved retention and esthetic outcome by increasing the vertical dimension and the lip support using CAD-CAM technique and the ball attachment.

For a full-mouth fixed prosthetic treatment of the edentulous patient, it is essential to confirm the proper tooth position and thorough evaluation of the remaining alveolar bone and soft tissue before surgery. CAD-CAM dentistry and guided implant surgery have such advantages of providing simultaneous planning of surgery and prosthetic treatment to ensure pre-knowledge of the treatment. In this clinical case, using the digital technology, digital temporary denture fabrication, esthetic evaluation before fixed prostheses treatment, and guided surgery planning was possible. After the surgery, previously obtained data was used for fabricating fixed temporary prostheses. Definitive zirconia prostheses transferred from the provisional prostheses were fabricated and functionally and esthetically satisfying results were obtained.

The aim of this study was to examine the impacts of pre-briefing using structured video simulations in the pre-hospital trauma care simulation-based education on simulation immersion, simulation confidence, and simulation satisfaction. For both the experimental group and the control group, orientations were conducted on the simulation environment. Subsequently, the experimental group watched a video of about 8 minutes, similar to the scenario situation, in which the goal and result of the training were presented. The control group, on the other hand, conducted a classical way of orientation related to the scenario during the same time period. In addition, the experimental group and the control group underwent simulation practice in the same situation for 12 minutes, and debriefing was performed for 40 minutes by the same research assistant. Afterwards, we measured the simulation immersion, confidence, and satisfaction of the participants. Data were analyzed using χ² and independent t-test using the SPSS 22.0 program. It was found that the experimental group that conducted the pre-briefing using video had higher immersion and confidence than the control group. On the other hand, satisfaction was not significantly different between the two groups. The results indicate that pre-briefing using structured video was an effective educational method to increase simulation immersion and simulation confidence.
