Rubber impression materials are designed to maintain their elastic properties over time, which is crucial for accurate dental impressions. As these materials undergo setting and curing, they typically reach their optimal elasticity shortly after the process is complete. Over time, they are generally stable in their rubber-like characteristics, allowing for continued accurate reproduction of oral structures.

The improvement in elastic properties typically occurs due to the complete curing of the material, which enhances the strength and elasticity of the impression. This means that while some materials may experience minor changes, they do not usually deteriorate significantly, and often, their elasticity can stabilize or improve as they fully set.

In contrast, other considerations such as exposure to extreme temperatures may negatively impact their elasticity, which reinforces the notion of maintaining proper storage conditions to preserve their properties. This contrast highlights the importance of environmental factors on material performance over time.
