Aesthetic Restoration of Teeth: Advantages of Metal-Free Ceramic Crowns
Until recently, when a molar tooth suffered damage from cavities and subsequent degradation, a dentist could propose restoring the tooth with a resin filling if the nerve was removed and the tooth was extensively damaged. In more severe cases, a porcelain and metal crown was recommended. Over time, resin fillings could chip, leading to the development of secondary cavities, and the junction between the filling and the tooth's tissue was marked by pigments, giving the tooth an unattractive appearance. Porcelain and metal crowns often differed in appearance from adjacent teeth, caused changes in the color of the surrounding gums, and could even trigger allergic reactions in patients due to the metal.
Modern Dental Restoration
In modern dentistry, advanced techniques are used for the aesthetic restoration of molar teeth, including the restoration of a portion of the tooth with ceramic inlays, and if the damage to the tooth is more than 50%, metal-free crowns are used.
Ceramic Inlays for Dental Restoration
Ceramic inlays allow for the restoration of the tooth's original appearance, function, and color. During the ceramic inlay restoration procedure, minimally invasive methods are applied to the tooth's tissue, preserving the healthy portion of the tooth and avoiding pulp removal. The precise fit of the inlay to the tooth's tissue prevents the development of secondary cavities.
Technological advancements in dental restoration allow for the creation of a virtual image of the tooth on a computer and the modeling of a digital restoration on it. The obtained information is then transmitted to a milling block, which carves the restoration from ceramic based on the computer's specified parameters. The milled inlay is polished and fixed onto the tooth.
Advantages of Metal-Free Ceramic Crowns
At the Dental Clinic in Barcelona, metal-free ceramic crowns are offered as a high-quality alternative to porcelain and metal crowns. This is particularly relevant for patients with allergies to the metals used in the framework of porcelain and metal constructions. Metal-free ceramics are characterized by their high strength, long lifespan, hypoallergenic properties, and biocompatibility with the tissues of the oral cavity. These arguments play a decisive role in choosing the material for dental prosthetics at the Dental Clinic in Barcelona.
Metal-Free Ceramics Based on Zirconium Oxide and Zirconium Dioxide
Among the various types of metal-free ceramics used for making crowns, ceramic based on zirconium oxide and zirconium dioxide holds a special place. Zirconium is a metal, but when it chemically reacts with oxygen, zirconium oxide is formed, which is a ceramic material. Zirconium dioxide is a high-tech ceramic that has proven to be excellent in dentistry.
For a durable, aesthetic, and safe dental restoration, metal-free ceramic crowns are the ideal choice in modern dentistry.
