It solidifies into an elastic mass capable of producing a negative reproduction of the oral cavity (an impression) (Poling et al. Once this is done, they will mix the alginate powder with water to create a smooth, spreadable consistency. compressive strength : 5000-8000 gm/cm2. Using digital scanners eliminates these problems; however, digital scanners have their own types of errors that can occur. Alginate mixed with silver nanoparticles showed no inhibitory effect on S. aureus and C. albicans, but the number of E. coli colonies were counted in the group 1000 ppm was significantly lower than 500 ppm (P = 0.001). Results: Due to their low cost and ease of use, alginate impression materials have been widely used for the past sixty years in dentistry.2,3Alginate mixing can be done in three different ways: manual, semi-automatic, and full automatic. To get these impressions, they use a material known as alginate. While there are many systems available, the one thing is common is that they all provide potential for greater accuracy, precision, speed, and patient comfort when compared to traditional impressions.

[ 1] The oral cavity is a host to many microbial agents, and it is shown that oral fluid could mix into the impressions. The material is scooped up and loaded into the tray from the lingual portion of the tray (it should only take twothree portions of material to fill tray). The following are characteristics of an ideal alginate impression material: Patient should be seated in an upright position.
