Conway和Baumhammers 4以及Saltzberg等人5证明了扫描电子显微镜（SEM）在评估牙齿缺损边缘方面的有用性。清晰度和极深的视野使SEM成为观察抛光或精加工前后铸件边缘的理想工具。SEM在此类调查中的优点现在已经得到了很好的确立。本研究的目的是用SEM显微照片来证明传统精加工工艺的效果，并显示金铸件的边缘是否发生任何移动。将在银模具上精加工前后的铸金牙体的适合性和适应性与精加工前后的铸件与预备好的牙齿边缘的适合性和适应性进行比较。
Conway and Baumhammers4 and Saltzberg et al5 demonstrated the usefulness of the scanning electron microscope (SEM) in evaluating margins of dental restorations. The clarity and extreme depth of field of the views make the SEM an ideal tool for observing margins of cast restorations before and after burnishing or finishing. The merit of the SEM in such investigations is now well established. This study was conducted to demonstrate with SEM photomicrographs the effect of conventional finishing procedures and to show if any movement of the margins of gold castings occurs. The fit and adaptation of cast gold restorations before and after finishing on silver dies was compared with the fit and adaptation, before and after finishing, of the castings to the margins of the prepared teeth.
