项目摘要

Preceding the final clinical test, various basic evaluation tests are being performed on dental metals regarding biological and chemical factors which are especially important among the other criteria. Since 1985, observation and analysis by EPMA have been performed in our research, on the metals used in immersion tests or subcutaneous implant tests, and restorations removed from oral environment, to study the changes in their surface condition or quantity of the constituent elements. As a result, basic idea of the fine changes in dental metals which have gone through basic evaluation tests or long terms of intra-oral usage, is becoming clear. The next step was to periodically evaluate the changes in the intra-oral restorations fabricated by different standardized alloys. Observation and analysis of the specimen is performed at the same site before and after the tests for comparison, and thus, accurate reproduction of the analyzing area is essential. Furthermore, due to increase in number of the specimen, much efficient analysis was being required. Since the former EPMA system did not meet our expectations, automatic quantitative analysis system was developed in this project to improve the accuracy and efficiency for observation and analysis. This is a system which enables the computer to memorize a large number of analyzing areas by coordinate memory device. It is connected to the stage control unit which already has been programmed for automatic analysis. Moreover, analyzing accuracy was much improved by the development of light sensed encoder, direct current motor, and the program that eliminates backlash during its gear operation. Consequently, even under high magnification (>5000X), it showed an excellent reproduction in recalling the analysis area from the memorized coordinates, and much higher analysis efficiency was achieved.

在最后的临床试验之前,正在对牙科金属进行关于生物和化学因素的各种基本评价试验,这些因素在其他标准中尤为重要。自1985年以来,我们在研究中对浸入试验或皮下种植试验中使用的金属以及从口腔环境中取出的修复体进行了EPMA观察和分析,研究其表面状态或组成元素数量的变化。因此,经过基本评估测试或长期口腔内使用的牙科金属的细微变化的基本概念变得清晰起来。下一步是定期评估不同标准化合金制作的口腔内修复体的变化。在试验前后在同一地点对试样进行观察和分析,以便进行比较,因此,准确再现分析区域是必不可少的。此外,由于标本数量的增加,需要更有效的分析。由于之前的EPMA系统没有达到我们的预期,为了提高观测分析的准确性和效率,本项目开发了自动定量分析系统。这是一种通过坐标存储装置使计算机能够记忆大量分析区域的系统。它连接到已经被编程为自动分析的阶段控制单元。此外,通过开发光感编码器、直流电机和消除齿轮运行间隙的程序,大大提高了分析精度。因此,即使在高倍率(>5000X)下,它也能很好地从记忆的坐标中提取分析区域,并获得更高的分析效率。(第55届口腔学会年会上报告)
