Abstract

Dimensional steadiness and exactness of vinyl polysiloxane (VPS) elastomeric impression materials have resulted into their wide spread usage in restorative dentistry. They are excessively popular because of their best elastic recovery, no by-product during polymerization, allowing second pour, applauding handling attributes, clean, odorless and being tasteless. However, they are significantly hydrophobic in nature and a minimal surface energy which renders them intractable to moisten with gypsum slurries. Therefore, surfactants are incorporated to improve wetting and reduce hydrophobicity. This narrative review highlights the research done on refinement of wettability and reduced hydrophobicity of the VPS impression material.
