Quizplus · Accepted Answer

Alginate is the most commonly used irreversible hydrocolloid material for preliminary impressions due to its ease of use, low cost, and ability to provide accurate detail reproduction. Light-bodied materials are used as a wash material with the alginate for better accuracy. Polysulfide and polyether materials are more expensive and are typically used for final impressions.
