J Soc Chem Ind Jpn 29:509517, Benegas JC, Di Blas A, Paoletti S, Cesro A (1992) Some aspects of the enthalpy of dilution of biological polyelectrolytes. Is stiffness among the ideal requirements of a dental impression material? 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. The characteristics of the polysaccharide in solution are tackled looking both at the equilibrium properties (thermodynamic properties) and at the nonequilibrium ones (viscosity in dilute and semidilute solution). The Ca2+ crosslinks bridging the alginate chains in the network appear to be labile. 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 non-toxic and non-irritant biomaterial available in a paste form, preserving its elasticity under heat, which is used as a printing material for measuring teeth in dental. 2012 Jul 1 ; 13 ( 4 ):221-5. doi: 10.3390/ijms22052485 G.
