What is a common attribute of addition silicone materials?

Addition silicone materials, also known as polyvinyl siloxanes (PVS), are known for their exceptional dimensional stability after curing. This means that once these materials harden or set, they maintain their shape and dimensions effectively, even in the presence of temperature fluctuations or other environmental factors. This stability is crucial in dental applications, such as for making impressions, where accuracy is paramount to ensuring a proper fit for restorations and prosthetics.

The chemical process of addition polymerization that these silicones undergo contributes to their stable volume characteristics, contrasting with some other types of materials that may undergo shrinkage or distortion over time. Therefore, the intrinsic properties of addition silicones make them highly reliable for situations requiring high precision and consistency. This stability component is especially vital in prosthetic dentistry, where the exact replication of a dental structure is essential for patient satisfaction and treatment success.
