Dentsply Jeltrate Alginate Impression Material Chemwatch: 4993-56 Version No: 5.1.1.1 Safety Data Sheet according to WHS and ADG requirements Issue Date: 27/06/2017 Print Date: 04/01/2018 S.GHS.AUS.EN SECTION 1 IDENTIFICATION OF THE SUBSTANCE / MIXTURE AND OF THE COMPANY / UNDERTAKING Product Identifier The immediate method (measured buccolingually and diagonally) produced more accurate casts. After thorough mixing, a homogenous material is obtained, which is used to make the desired impression. In dentistry, alginate impression materials are used to take impressions of teeth in orthodontics, prosthodontics, and other dental practices. Dimensional accuracy is one of the most important characteristics for a dental impression material. endobj The composition also includes a silane coating that is added to either the filler or to the alginate material as a whole. << A dental or medical alginate impression composition is provided. >> Preparation of the alginate composition is achieved in the same manner as Example 1.

Calcium sulfate(16%) Reacts with the potassium alginate to form the gel. Furthermore, when water is added to the alginate powder, since the material is hydrophobic, it becomes much more difficult for the practitioner to achieve complete incorporation or absorption of the water into the material. Grant and Hackh's Chemical Dictionary; Grant, ed. The inventive alginate impression composition is advantageous since it does not require use in a dry condition. 2. When the powder is mixed with water, the alginate powder dissolves, as does the calcium sulfate and sodium phosphate. However, alginate does have poor dimensional stability and will distort if left to dry or left in water for too long. ��jsFB��X��g�����R�5�=�|�W��VCZz�77��t�.���7�E��ڢZs��TS�>����y��,&�j��h�~��x. – In dentistry, we take impressions of teeth and their supporting structur es.

The resulting silane coated alginate composition was recovered (24.50 grams)--weight recovery was 98 percent. Like agar, it is a natural Hydrophillic Colloidal Polysaccheride extracted from brown seaweed. You will find that all of our alginate impression material has been chosen with great consideration for character of the material. Dental Material 1. A master cast was fabricated of an acrylic resin due to its low water absorption and low thermal conductivity. The reactive constituents of alginates are sodium or potassium salts of alginic acid and calcium sulfate that when mixed with water form a sol. Particular attention is devoted to the definition of the comonomer sequence and its determination together with chemical and biochemical modifications of alginate. JEFFREY M. KADEN, ESQ. In a powdered dental impression composition, comprising at least one water-soluble alginate, a gelling agent, a gelling regulator and mineral fillers, the improvement wherein said mineral fillers are coated with from about 1% to 10% by weight of a hydrolyzed gelatin. The resulting washed mixture was then placed in an oven and heated to 90° Centigrade for about four hours. The study was divided into four groups. What is claimed is: 1. comprising β-d-mannuronate (M) and its C-5 epimer α-l-guluronate (G). A retarder may be added to the inventive composition in an amount between about 1 and 20 weight percent based on the weight of the overall composition. The impression tray was placed over the acrylic master cast and hand pressure was slowly applied for about 30 seconds in order to ensure a proper fit. Basic formulation of dental alginate impression material composition. In addition, the inventive alginate impression composition has a much stronger matrix as compared to conventional alginate compositions, resulting in a tougher wear-resistent matrix. Product Use: Dental product: Impression Material. Alginate Impression material is an Elastic, Irreversible Impression material which is used to take the impression of both Dentulous and Edentulous Impressions. 2. The resulting saline coated alginate composition was then recovered (24.68 grams)--weight recovery was 98.72 percent. MATERIAL SAFETY DATA SHEET BASIS ALGINATE IMPRESSION MATERIAL Note: This MSDS was prepared in accordance with the requirements of the OSHA Hazard Communication Standard (29 CFR 1910.1200) and is to be used only for this product. 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. The resulting silane coated alginate composition was removed (15.5 grams)--weight recovery was 96.88 percent. This invention relates to a dental or medical impression composition, and more particularly, to an alginate impression composition that is hydrophilic. - Dr May Ali. Moreover, in surgical procedures, because the eventual prosthesis is often held in by undercuts in the surgical site, it is advantageous to have an alginate impression material that is strong, flexible enough to accurately record all internal surface architecture, and with the ability to free itself from the undercut without tearing upon removal from the site. Product And Company Identification . The resulting washed alginate mixture was then placed in an oven and heated to 90° Centigrade for about four hours. [�8m�m �tҼdQ��w��H��^� The present chapter deals with the description of the main characteristics of alginate as a material. H 2 O, potassium sulphate to reduce the expansion, borax to reduce the rate of setting, and starch to help disintegration of the impression on separation from the plaster/stone model. The inventive composition of Group 4 comprised 20.5 grams of powder and 40.0 grams of water. Reference groups were also created mesiodistally on the distolingual cusp of the left and right first molars. Impression Materials A. COMPOSITION : Potassium alginate(15%) Comes from seaweed; is used as a thickening agent. Page 1 of 7 . /Length1 16148 1: Setting reaction of the alginate impression material.

Alginate is a linear acidic polysaccharide. This is because a greater quantity of water is required in order to facilitate manipulation of the impression material. All rights reserved. CONSTITUTION: An alginate impression material composition contains 0.1-85wt.% of pulverized cereal husk or wood meal. The silane ingredient of the inventive composition is placed on the surface of the alginate material in order to render the material hydrophilic. PURPOSE: Provided is an alginate impression material composition which is harmless to the human body, and not nearly separated from other impression materials due to the density difference with excellent tearing strength. Optionally, one or more antimicrobial agents may be added to the inventive composition in an amount between about 1 and 10 weight percent based on the weight of the overall composition. Manufacturer: Kerr Corporation 1717 W. Collins Ave. Orange, CA 92867-5422 Alginate is a material used in dentistry to make impressions of adjacent teeth and soft tissues. ��@����(zѠ@}��LlR� �=� ��l#/w)��5����Wñ�|�o�x {�(���ϙ��B� ���3��S3+Kc���v \�\q� z4����Q�3����j�%)��4��h��uWD�Q��,�5�P{��E� Examples include sodium phosphate, potassium phosphate, potassium oxalate, sodium oxalate, sodium carbonate, and potassium carbonate. << One hour storage in a wet paper towel.
