Hydrophilic vinyl polysiloxane impression materials.
VPS impression materials that contain a surfactant cannot be considered as hydrophilic, rather they are probably less hydrophobic. More VPS products that contain surfactants are expected to be introduced to the market. It is yet to be proven that surfactant-containing VPS materials have a better wettability than polyether-based impression materials. The current data still indicates that polyethers are more hydrophilic. The less hydrophobic behavior of the surfactant-containing VPS may provide a significant advantage in clinical practice. Due to this advantage, the author suggests that clinicians using VPS as their preferred elastomeric impression material should consider switching to surfactant-containing VPS impression materials.
