Impression materials that have mechanical properties permitting considerable elastic deformation but that return to their original form are classified as: A. Alginate is an elastic hydrocolloid dental impression materials to obtain negative reproduction of oral mucosa such as to record soft-tissue and occlusal relationships. From this replica, or impression, a model can be made that is used in the construction of full dentures, partial dentures, crowns, bridges and inlays.

Alginate is a powder material that contains sodium alginate, calcium sulfate, trisodium phosphate, diatomaceous earth, zinc oxide, and potassium titanium fluoride. DPI Chromatex Alginate Impression Material. Filed Under: B.D.S, Dental Materials Tagged With: ideaal impression material, ideal impression, ideal properties of impression material. Most common method of obtaining an impression for space maintainer, an alginate impression with subsequent dental stone model, has disadvantages offending to distort over time as water evaporates from or absorbs into impression thereby causing inaccuracies in impression and subsequent stone casts. [ 1] The oral cavity is a host to many microbial agents, and it is shown that oral fluid could mix into the impressions. However, due to nonconformities in mixing time or proportions of material utilized, certain properties of the gel can be effected and diminish. Carbohydr Res 154:239250, Skjk-Brk G, Smidsrd O, Larsen B (1986b) Tailoring of alginates by enzymatic modification in vitro. 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. Impression materials are used to copy the teeth and surrounding oral structures by creating a dental impression poured with dental plaster to fabricate a dental cast. The setting behavior of calcium alginate impression materials was investigated by monitoring the viscosity, calcium ion activity, and shear modulus during the reaction. Biomacromolecules 6:8898, Donati I, Holtan S, Mrch YA, Borgogna M, Dentini M, Skjk-Brk G (2005b) New hypothesis on the role of alternating sequences in calcium-alginate gels. Next, the mixture should be spatulated against one side of the bowl with the flat portion of the buffalo spatula, turning the spatula over at times to ensure a smooth bubble free mix (Poling et al. Although alginate impression material has dimensional stability problems, it can produce an accurate stone cast if handled properly. Patient should rinse and all alginate should be removed from the patients face. alginate can also be used in a perforated stock metal tray [2-5]. Alginate setting time can be changed by altering the mixing time or water: powder ratio. 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. After the Impression is taken, Dental Stone or Die Stone or Plaster of Paris is poured into the Impression replica to create a patient model which will be removed from impression once it is set or hardened to be used. 2009. Flashcards. Correlation between chemical and physical properties of alginate gel beads. 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).
