What characterizes elastomeric materials in dental applications?

Elastomeric materials in dental applications are primarily characterized by their ability to be self-curing. This means that these materials can undergo a chemical reaction that allows them to set or harden without the need for external heat or light sources. In dental practices, self-curing elastomers are commonly used for making impressions, as their elasticity allows for the capture of fine details while maintaining dimensional stability.

Self-curing elastomeric materials provide efficiency in dental procedures because when they are mixed, they start the curing process automatically, facilitating better workflow. This property is especially beneficial in creating impressions for crowns, bridges, and other restorations.

While elastomeric materials are often used for impressions, they are not limited to this single application (which would make that characterization inaccurate). Additionally, they can be mixed; proper mixing is essential for optimal performance but does not disqualify them from being considered elastomeric. Finally, elastomeric materials are available in both liquid and solid forms, allowing for versatility in their use. Thus, the defining characteristic of being self-curing accurately reflects a significant aspect of elastomeric materials in dental applications.
