Alginate Materials and Dental Impression Technique: A Current State of the Art and Application to Dental Practice. [PDF]

Mar Drugs, 2018
Hydrocolloids were the first elastic materials to be used in the dental field. Elastic impression materials include reversible (agar-agar), irreversible (alginate) hydrocolloids and synthetic elastomers (polysulfides, polyethers, silicones). They reproduce an imprint faithfully, providing details of a high definition despite the presence of undercuts ...
