What type of silicone is known for its ability to work well in moist environments for impressions?

Addition silicone is the correct choice due to its excellent hydrophilic properties, which allow it to perform effectively in moist environments. This type of silicone is known for its precision and dimensional stability, making it ideal for capturing intricate details in dental impressions, even when there is some moisture present. The unique chemical composition of addition silicones also contributes to their resistance to water, enhancing the quality of the impressions compared to other materials.

In contrast, condensation silicone is typically more limited in its ability to handle moisture, as it can be less stable in wet conditions. Polysulfide, while a resilient material, does not have the same level of moisture compatibility and can present challenges related to its working time in damp environments. Reversible hydrocolloid is another material used for impressions, but it is largely reliant on water and is less stable than addition silicone in moist conditions, making it less favorable for precise impressions when there is significant moisture.
