Which of the following statements about setting times of impression materials is true?

Polysulfide impression materials are known for their relatively long setting times compared to other types of impression materials. This characteristic allows for greater flexibility in their use, as they provide adequate working time for the dentist to manipulate and adapt the material before it begins to set.

In the context of clinical practice, the long setting time of polysulfides can be advantageous, particularly in situations where detailed impressions are needed, as it allows for careful placement and reduces the risk of distortion during the impression-making process. While other materials like silicones and polyethers may offer shorter setting times, polysulfides are distinct for their extended working period, which is essential for capturing fine detail in the impression.

Understanding the different setting times of impression materials aids dental professionals in choosing the appropriate material for specific procedures, ensuring optimal results in patient treatment.
