It is said that a first impression is everything, and this is especially true in the field of dentistry. This article will discuss the 3 most common classifications of impression materials: polyether (PE), vinyl polysiloxane (VPS), and a hybrid material called vinyl polyether siloxane (VPES).Why is alginate irreversible?
Agar is a reversible hydrocolloid because it can pass repeatedly between highly viscous gel and low viscosity sol simply through heating and cooling. However, alginate once converted to the gel form cannot be converted back into the sol, and is therefore said to be irreversible hydrocolloid material (4).What is a PVS impression?
