A scanning electron microscope and heating microscope are used to visualize the microstructure of dental porcelain during fabrication and demonstrate the relationships of the porcelain firing conditions to the translucency and hue of the completed restoration. The firing cycle, temperature, rate of temperature rise, holding time, and cooling time influence the distribution of the sintering, glass, and crystal phases in the microstructure of the porcelain. Observing the changes of fritted porcelain and opacifiers as they progress through the firing cycle demonstrates how the quality of the final ceramic restoration is largely dependent on the firing conditions chosen.
扫描电子显微镜和加热显微镜用于观察牙科陶瓷在制作过程中的微观结构，并展示陶瓷烧制条件与最终修复体的半透明度和色调之间的关系。烧制周期、温度、升温速率、保温时间和冷却时间会影响陶瓷微观结构中烧结相、玻璃相和晶相的分布。观察预熔瓷和遮光剂在烧制周期中的变化，可以看出最终陶瓷修复体的质量在很大程度上取决于所选择的烧制条件。
