Alginate Materials and Dental Impression Technique: A Current State of the Art and Application to Dental Practice. Detail reproduction was minimally affected by the variation in powder/water ratio.ĭetail reproduction polymeric alginate impressions powder/water ratio tear strength viscosity.Ĭervino G., Fiorillo L., Herford A.S., Laino L., Troiano G., Amoroso G., Crimi S., Matarese M., D’Amico C., Siniscalchi E.N., et al. On the other hand, no clear clinical difference was detected when examining dental impressions mixed with a different powder/water ratio.Īlthough increasing the powder/water ratio of mixed alginate raised the resultant viscosity and tear strength by an in vitro test, clinically, no clear difference in tearing was detected. Both alginate mixtures reproduced two scribed lines in a detail reproduction test. The alginate specimens mixed with a higher powder/water ratio showed a higher viscosity and tear strength compared to those with a lower powder/water ratio. Clinical dental impressions were examined by stereomicroscope. For detail reproduction, a die with three scribed lines was used. For the tear strength test, V-shaped specimens were used. Two commercial alginate products were mixed in different viscosities. To evaluate this variation's effect on patients' impressions. To analyze the effect of alginate powder/water ratio variation on viscosity, tear strength and detail reproduction by in vitro tests, and 2. Alginate impression is a common dental polymeric material, presented as powder to be mixed with water.ġ.
