Which impression material provides the best fine detail, elastic recovery, and dimensional stability?

Vinyl polysiloxane (VPS) is widely recognized as the gold standard impression material for high precision due to: Excellent elastic recovery Superior dimensional stability Ability to capture fine detail It is ideal for procedures requiring high accuracy, such as crown and bridge impressions. Other materials: Alginate is economical but lacks dimensional stability and detail accuracy. Polysulfide has good elasticity but inferior detail capture and stability. Polyether has good detail and stability but is less elastic than VPS.
