Alginate is one of the most frequently used dental impression materials.

Sodium / Potassium Alginate forms elastic, irreversible hydrocolloid impression material.

When mixed with water containing a calcium source, it makes a smooth gel-like consistency that sets firmly enough to mold.

Alginate impression material produces accurate dental impressions even in the presence of saliva.

Further Alginate is a hypoallergenic (unlikely to cause an allergic reaction) material making it well suited for dental molds.
