Porcelain-fused-to-metal crowns have broad applications. They can correct misaligned teeth unsuitable for other orthodontic treatments, address tooth discoloration, restore damaged teeth, and repair cavities. This restoration method minimizes porcelain chipping, offers lifelike color and natural form, and delivers excellent aesthetic results.
What is Porcelain-Fused-to-Metal Restoration?
Porcelain-fused-to-metal restoration is a dental restoration technique and one of the most commonly used methods today. It involves creating a restoration using porcelain-fused-to-metal crowns. For missing or damaged teeth, a cast precious metal core is used as the inner support structure. Porcelain is then fused to the exterior to achieve a restoration that closely matches the color and function of natural teeth.
Excellent Marginal Seal of Porcelain Crowns
Porcelain crowns offer superior marginal seal. Their fabrication requires precise marginal adaptation, with a 1mm subgingival margin. Combined with specialized non-water-soluble bonding materials, this ensures a secure seal.
Porcelain Crowns Protect Teeth
They safeguard tooth structure and pulp. Teeth requiring crowns are often discolored or decayed. Once the porcelain crown is placed, the entire natural tooth is encased within the crown. Chewing forces are directed onto the crown, preventing fractures or chips. The bonding agent and porcelain layer used to attach the crown also providepossess excellent insulation properties, shielding the pulp from external irritants. Porcelain-Fused-to-Metal Crowns Offer Superior Biocompatibility They exhibit excellent biocompatibility, particularly crowns made from biocompatible precious metals or all-ceramic materials. Their electrochemical inertness provides corrosion resistance and prevents tissue allergies. In contrast, standard stainless steel crowns may develop a dark gray margin visible at the gum line after prolonged wear.
High hardness of porcelain crowns
Exceptional strength. After gold alloy and ceramic powder fuse at high temperatures, the resulting structure can withstand oral chewing forces. The bond between precious metals and ceramic crowns is exceptionally strong.
