/Length1 16148 Reference groups were also created mesiodistally on the distolingual cusp of the left and right first molars. Impressions are used in the dental surgery to produce accurate (varying degrees of accuracy) negative reproductions of the patients’ teeth, surrounding tissues and dental arches. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract: The aim of the present study was to investigate the effect of various alginate impression materials compositions on the recovery from deformation property. �z3����PB��e�� ����ā`R�B! In order to better comprehend the inventive alginate impression alginate composition, the following examples are provided. The stone casts were allowed to set for about 45 minutes before removal and left to dry for 24 hours before any statistical measurements were taken, in accordance with standard statistical practice. All other materials that were studied were similar statistically. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT. The inorganic composition of the alginate materials is described in Figures 1–5.In the past, lead salts were used to replace calcium to enhance the gel through the formation of lead alginate [].However, lead is not essential to the formulation of high-quality alginates. 1 - IDENTIFICATION Like agar, it is a natural Hydrophillic Colloidal Polysaccheride extracted from brown seaweed. Alginate impression material is considered one of the groups often referred to as "elastic impression materials". © 2004-2021 FreePatentsOnline.com. What Is Alginate Made Of? The resulting saline coated alginate composition was then recovered (24.68 grams)--weight recovery was 98.72 percent. DeTrey Zelgan®2002 is a dust-free alginate impression material complying with ISO 1563 and EN 21563, respectively. What is claimed is: 1. – Alginate Impression materials set by a chemical reaction that cross-links a carbohydrate polymer. In order to determine if the alginate composition was hydrophilic, a test sample was used by placing a drop of water thereon to determine if absorption took place. SAFETY DATA SHEET . Alginate - Impression - Henry Schein Australian dental ... ... Alginate >> Different types of impression materials are available. Several modifica-tions were made in the composition of conventional alginates to address their shortcomings. Calcium sulfate To react with potassium alginate to form an insoluble calcium alginate gel. �E9��J�ti�����O�zR4���._�Vܨ4Zl��^�X� Alginate imp. ; 5th ed. The preferred filler is diatomaceous earth. Alginate Impression Materials 06/19/19. Specifically, the filler enhances the stiffness of the alginate gel, produces a smooth body texture, and ensures a firm gel surface. All mixtures were performed at room temperatures in a stock water solution which was also stored at room temperature.

In accordance with the invention, either the entire alginate mixture is treated with the silane coating, or the filler ingredient is separately treated with the silane coating, depending upon the composition that the practitioner desires.

This is because a greater quantity of water is required in order to facilitate manipulation of the impression material.

In order to prepare the filler composition, 13.0 grams of diatomaceous earth were placed into a screw-cap vial. The silane is selected from the group of triaminofunctional silane, gamma-methacryloxypropyltrimethoxysilane, gamma-glycidoxypropyltrimethoxysilane, gamma-aminopropyltrimethoxysilane, and N-beta-(aminoethyl)-gamma-aminopropyltrimethoxysilane.
