A comparative analysis of porcelain teeth and Porcelain-fused-to-metal (PFM) teeth: Compared with PFM teeth, all-ceramic teeth have an aesthetic effect that is closer to natural teeth. All-ceramic teeth are made of ceramic blocks and feature excellent transparency, gloss and strength, with a natural and realistic appearance. The metal inner crown of porcelain-fused-to-metal teeth is made of opaque material, and the outer layer is covered with a colored porcelain layer, which causes "black lines" to appear at the edge and affects the appearance. In addition, the metal layer of porcelain-fused-to-metal crowns is prone to oxidation in the oral cavity to form gray oxides, which deposit near the gums, causing them to turn grayish-black. All-ceramic teeth have no metal layer, avoiding this problem and are safer and more reliable. Therefore, all-ceramic teeth are superior to porcelain-fused-to-metal teeth in terms of aesthetics and biocompatibility, making them an ideal choice for those pursuing a high-quality life.
