Prostho vs Materials — Key differences for NEET MDS
Most accurate = Addition silicone PVS. Alginate = irreversible hydrocolloid. Agar = reversible hydrocolloid. Elastomeric ranking: Polysulfide least accurate. Condensation silicone releases alcohol. Polyether stiffest hydrophilic. Addition silicone most accurate. ZOE = mucostatic impression. Working time affected by temperature.

Polysulfide = longest setting time messiest = lead dioxide accelerator. Polyether = stiffest most hydrophilic = initial rigidity. Alginate = irreversible hydrocolloid = snap set. Agar = reversible hydrocolloid = high detail low strength. Impression plaster = most rigid.
