lasiionomeeritäytteitä

Lasiionomeeritäytteitä, commonly known as glass ionomers, are restorative dental materials used to fill cavities and treat tooth decay. They are a type of dental cement that chemically bonds to tooth structure, providing a durable restoration. Glass ionomers are distinguished by their ability to release fluoride ions, which helps to prevent secondary decay and strengthen the remaining tooth enamel. This makes them particularly useful in areas prone to cavities or for patients with a high risk of developing them.

The composition of glass ionomers typically includes fluoroaluminosilicate glass powder and an aqueous solution of polyalkenoic acid. When mixed, these components react to form a hardened matrix. They are available in various formulations, some of which are designed for aesthetic purposes and can be matched to the natural color of teeth, while others are primarily used for their therapeutic properties.

Glass ionomer restorations are often chosen for primary teeth, as well as for non-load-bearing restorations in adults, such as those on the root surfaces of teeth. They are also frequently used as a base material under other restorative materials like composite resins. The setting time and physical properties can vary depending on the specific product. While generally considered safe and effective, like all dental materials, they can have limitations and are subject to wear over time.
