Combine these new advantages with the wellknown benefits of Impregum brand impression material from 3M ESPE and you get unmatched accuracy and initial hydrophilicity in three consistencies: The tray will be firmly placed on the upper or lower teeth (depending on where the dental work is being done) for a couple of minutes. Sodium alginate is used as an impression -making material in dentistry, prosthetics, lifecasting, and for creating positives for small-scale casting . The following are characteristics of an ideal alginate impression material: cost effective, easy to mix, adequate flow properties, nontoxic or irritating, sufficient strength to avoid tearing material upon removal from the mouth, and acceptable working and setting times. Alginate is a hypoallergenic (unlikely to cause an allergic reaction) material that dental professionals use to take accurate teeth impressions for various oral devices and treatments.

Effect of Different Disinfectants on Staphylococcus aureus and Candida albicans Transferred to Alginate and Polyvinylsiloxane Impression Materials. doi: 10.1016/j.heliyon.2020.e04686. The gelation time is primarily controlled by the concentration of Na4P2O7 in solution acting as a retarder, while the level and particle size of the alginate and CaSO4 X 2H2O also affect the kinetics through the dissolution rates and concentration effects. Correlation between chemical and physical properties of alginate gel beads. PHYSICAL PROPERTIES OF ALOINATE . Even if a lot of rubber base impression materials with good physical properties was used to take impressions, the alginate material was able to prove its usefulness and has been a staple of most dental practices the world. Self-disinfecting impression materials would reduce time and energy needed for impression disinfecting process in clinic.
