General Description
Dental porcelain is a type of ceramic material commonly used in dentistry to create prosthetic crowns, bridges, and veneers. It is composed of a mixture of various ceramic powders, such as feldspar, silica, and alumina, that are heated and fused together at high temperatures to form a durable and aesthetically pleasing material. Dental porcelain is known for its natural-looking color, translucency, and biocompatibility, making it an excellent choice for restorations that can closely mimic the appearance and function of natural teeth. It also has the advantage of being resistant to staining, providing long-lasting results for patients seeking dental cosmetic enhancements.
