Porcelain is fired under vacuum for several reasons. The primary reason is to prevent undesirable opacity in the porcelain. When porcelain is fired in a vacuum, it allows for the removal of air and other gases from the firing chamber. This helps to eliminate any impurities or bubbles that may be trapped within the porcelain, resulting in a more translucent and aesthetically pleasing final product.
Another reason for firing porcelain under vacuum is to ensure consistent and predictable firing conditions. By creating a vacuum environment, the firing process can be tightly controlled and monitored. This allows for precise temperature and heat rate control, which is crucial for achieving optimal levels of maturity in the porcelain. It also helps to maintain important features of the restoration, such as surface texture, translucency, value, hue, and chroma.
Furthermore, firing porcelain under vacuum helps to improve the overall quality and longevity of the restoration. The vacuum environment helps to reduce the risk of thermal shock or distortion during the firing process. It also helps to eliminate any potential contaminants that may be present in the firing chamber, ensuring a clean and pure firing environment for the porcelain.
In summary, firing porcelain under vacuum is essential for achieving optimal aesthetics, maintaining consistent firing conditions, and ensuring the highest quality and longevity of dental restorations. The vacuum environment helps to eliminate impurities, control the firing process, and prevent undesirable opacity in the porcelain.
