What is the setting time for polysulfide impression material?

Polysulfide impression materials are known for their time-dependent setting characteristics, and a setting time of approximately 12-14 minutes is typical for this type of material. This extended setting time allows the polysulfide to adequately undergo its polymerization process, resulting in an accurate impression. The setting process involves the cross-linking of polymers, which is crucial for achieving the desired dimensional stability and detail reproduction in dental impressions.

In comparison to other impression materials such as alginate or polyvinyl siloxane, which typically have shorter setting times, polysulfide's longer setting period can be advantageous in certain clinical situations where more time is needed for complex impressions or for capturing fine details. Additionally, understanding the properties of polysulfide, including its working time and setting time, is important for clinicians to manage their workflow effectively during procedures that require accurate impressions.
