Figure 8.3.1: Radiographic image teeth #8 and #9. 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. 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. Aquasil Ultra+ is a quadra-functional modified siloxane impression material that has superior hydrophilic properties.
