How sensitive are polysulfide rubber impression materials to temperature when curing?

Polysulfide rubber impression materials are quite sensitive to temperature during the curing process because variations in temperature can significantly affect the chemical reactions involved in their setting. Higher temperatures can accelerate curing, potentially leading to a faster, uncontrolled setting which may compromise the quality and dimensional accuracy of the impression. Conversely, lower temperatures can slow down the curing, making it difficult for the material to set properly within the desired time frame, which could also affect the final impression's accuracy.

This sensitivity emphasizes the importance of maintaining a consistent and appropriate temperature environment when using polysulfide materials for dental impressions. Understanding this characteristic is crucial for dental practitioners, as it helps ensure successful outcomes in various clinical scenarios involving impression-taking.
