Which materials are commonly used for direct restorations?

The selection of materials for direct restorations is crucial for achieving good clinical outcomes in dentistry. Amalgam, composite resins, and glass ionomer are commonly used materials in this context due to their specific properties and benefits.

Amalgam is a durable material made from a mixture of metals that is commonly used for posterior teeth due to its strength and longevity. It is particularly effective in bearing the forces of chewing.

Composite resins are favored for their aesthetic qualities, as they can be closely matched to the color of natural teeth. They are versatile and can be used for both anterior and posterior restorations, allowing for aesthetic restorations that blend seamlessly with the surrounding tooth structure.

Glass ionomer is notable for its ability to release fluoride, which can help provide some degree of protection against further decay. It also adheres well to tooth structure and can be used in various clinical situations, including as a liner or base in deeper cavities.

In contrast, while materials such as silicone and plaster might serve specific functions in dentistry, such as impression materials or models, they are not utilized for direct restorations. Temporary and permanent cements play roles in the cementation of crowns or other indirect restorations but do not fit the definition of direct restorations themselves. Therefore
