Dental porcelain has found an increased number of applications in recent years with the development of new methods for the construction of porcelain veneers and intracoronal restorations. In addition, it is used in metal-ceramic and all-porcelain crowns and bridges for the restoration of anterior and posterior teeth.
This paper presents a review of a number of studies that have examined the visual and microscopic appearance and roughness of glazed, unglazed and polished porcelain surfaces using techniques such as, scanning electron microscopy and surface profilometry.
All have agreed that glazed porcelain provides a smooth and dense surface. Many have shown that polishing can produce an equally smooth surface, which may even be esthetically better. Some studies supported the use of polishing as an alternative to glazing. However, reports have shown that unglazed porcelain is more abrasive than glazed.
This paper aims to guide general practitioners in the proper polishing of adjusted porcelain in the dental office. The recommendations of various authors are summarized in Table I.
近年来，随着用于制作瓷贴面和冠内修复体的新方法的发展，牙科用瓷的应用越来越多。此外，它还用于金属烤瓷和全瓷冠桥，以修复前牙和后牙。
本文综述了多项研究，这些研究使用扫描电子显微镜和表面轮廓仪等技术，检查了上釉、未上釉和抛光瓷表面的视觉和微观外观及粗糙度。
所有人都认为上釉瓷提供了光滑致密的表面。许多研究表明，抛光可以产生同样光滑的表面，甚至在美学上可能更好。一些研究支持将抛光作为上釉的替代方法。然而，报告显示未上釉瓷比上釉瓷的磨损性更强。
本文旨在指导全科医生在牙科诊所对调整后的瓷进行正确抛光。各位作者的建议总结在表I中。
