J Bacteriol 178:17931799, PubMed The Japan Prosthodontic Society has recommended the alginate impression in either 0.1-1% Naocl solution for 15-30 min or 2-3.5% gluteraldehyde solution for 30-60 minutes. The main industrial applications of alginate as a natural polymeric material are linked to its stabilizing, viscosifying, and gelling properties and its ability to retain water. For patients with overactive gag reflex do the following: instruct patient to breathe deeply through the nose and focus on an object about 23ft away or raise one leg and lower up and down as if exercising. All rights reserved. Improper mixing over or under mixing with unset powder left in the improession, Prolonged mixing mixing beyond the mixing time will lead to lack of bond formation leading to tearing of material, Inadequate bulk thin segments tend to tear, in placed without adequate material tearing is common, Premature removal from mouth: Removal before completion of setting time will lead to tearing of the impression. 2014).
