Accurate impression is very important to achieve desirable prosthesis and there are many factors in taking a good impression. For example, types of impression material, types of impression tray, impression taking methods and so on. Recently individual tooth tray technique is accepted as obtaining good impression that can be applied to multiple abutment impression, heavy salivated patient, to minimize the effect of natural teeth' s undercuts and to reduce pain during cord packing procedures. The purpose of this study was to compare the accuracy according to materials and forms of the individual tooth tray which is clinically applied nowadays. Used materials in experiment were divided into 3 types (acrylic resin, Futar' occlusion, Blu-mousse) and forms were divided into 2 types (forming occlusal vent hole or not and forming marginal vent space or not). Stone master model from impression body and metal master model were measured by X-PLAN360d to compare occlusal surface discrepancy and marginal discrepancy. The results were as follows 1. In comparison of occlusal surface discrepancy and marginal discrepancy according to materials, groups with three materials showed no statistical difference. 2. In comparison of occlusal surface discrepancy and marginal discrepancy according to occlusal vent hole, groups with occlusal vent hole showed significantly less marginal discrepancy than groups with no occlusal vent hole(p<0.05). 3. In comparison of occlusal surface discrepancy and marginal discrepancy according to 0.5mm marginal-vent-space, groups with no 0.5mm-marginal-vent-space showed significantly less mar ginal discrepancy than groups with 0.5mm-marginal-vent-space(p<0.05). In summary, these results suggest that individual tooth tray made of 3 types of materials with occlusal vent hole and individual tooth tray made of acrylic resin with no marginal vent space showed good accuracy of impression. In addition, individual tooth tray which is made of bite registration materials may be more useful because of advantage in facility and timesaving aspect of fabrication.

PURPOSE: This study was conducted to compare the rates of industrial accidents in workplaces that adopted the 2011 Workplace Health Promotion Subsidy Scheme before and after the implementation. METHODS: The study analyzed the raw data of industrial accidents of 304 workplaces which received subsidies for health promotion activities in 2011. The raw data covered the period from February 2010 to July 2012, based on the dates of industrial accidents. RESULTS: Workplaces subsidized for health promotion activities reported fewer occurrences in staff injuries and illnesses than before the subsidization, as the total number of industrial accident victims dropped from 0.35 to 0.24. The rate of industrial accidents also dropped from 0.49 to 0.35, with the number of working days decreased from 35,433 to 23.867, about 33%. CONCLUSION: The study showed that financial support for health-promoting activities contributed to the decease in industrial accidents, which is an important indication advocating the need for corporate and government investment on workers health promotion programs. Furthermore, this study is also significant as it is the first research conducted in Korea to examine the impact of a workers health promotion project using a direct indicator, the rate of industrial accidents.

The first metacarpal base fracture is classified as extra-articular fracture, intra-articular fracture and epiphyseal injury. Intra-articular fracture was firstly described in 1882 by Bennett and Rolando described about Y shape comminuted fracture in the first metacarpal base in 1910. In 1938, Robert wrote about oblique fracture injured by first metacarpal base fracture. First metacarpal base fracture can be adjusted easily by C/R, but it is difficult to maintain the good axis. In case of fail of reduction, malunion, joint stiffness and traumatic arthritis can be shown as complications and finally some problems in grasping and pinching are resulted. Therefore, firstly the most accurate reduction, secondarily effective method to maintain the condition and thirdly the protection of limitation of motion are goal of treatment. Authors reviewed 17 cases treated by 0/R & C/R for the past 5 years from 1975 to 1980 at National Medical Center, especially reviewed the cases of which observation more than 1 year was possible. The results were as followings: 1. The incidence of first metacarpal base fracture was 1.0% of all fractures & dislocations. 2. Out of 17 cases, there were 14 male and right side 9 cases and left side was 8 cases. 3. The most common case of fracture was injury at work and traffic accident, sports injury, slipping down and falling down. 4. The method of treatment were C/R & percutaneous pinning in 10 cases and 0/R & K-wire fixation were 7 cases. 5. The result of treatment showed 8 excellent, 1 good, 1 fair, out of 10 cases of C/R and percutaneous pinning. In 0/R and K-wire fixation, 4 excellent, 2 good, and 1 fair showed out of 7 cases. 6. Soft tissue infection was appeared from 1 case of open fracture which accompanied second metacarpal fracture as complication and it caused adduction contracture in first web space.
