![]() 1,2,3 A typical formula for an alginate impression powder is: Potassium or Sodium alginate - the chief ingredient which comes from sea kelp and forms a sol in water. Also, if the ideal procedure is not followed, it will lead to a compromised fit of the final prosthesis and failure of the treatment. Dental alginate is an impression powder that, when mixed with water, will undergo a series of chemical reactions that will take it from a viscous sol to an elastic gel. Conclusion: The ideal materials, technique, and armamentarium are required for the long-term success of the treatment for fixed dental prosthesis. Most of the participants used addition silicone with single mix heavy body with light body technique for making final impression and some of them used polyether. Maximum participants used hemostat along with retraction cord. 80% of them used retraction cord for gingival retraction and only few of them used elecrosurgery, lasers, rotary curettage and gingifoam. Dental models enable dentists to perform a better. This procedure provides a tridimensional and accurate mouth replica, allowing dental work even in the absence of the patient. Results: Results shows that, majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. 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. Data were analyzed by using SPSS 19 software. Alginate is a high molecular weight linear polymer of anyhy- dro-D-mannuronic acid 1. Alginate impression mate- rials is essentially an alginic acid, which is obtained from brown seaweed (marine plant). A self-administered anonymous questionnaire was distributed to the participants. Alginate is an elastic and irreversible hydrocolloid impression material, which has been using in dentistry for many years. ![]() Ethical approval for the beginning of the study was obtained via Institutional Review Committee, Ibn Sina National College for Medical studies, Jeddah. Irreversible hydrocolloid impressions form an inseparable part of indirect restorations. sample, to record the original trace length. Alginate is an elastic, irreversible hydrocolloid impression material. Neocolloid (Zhermack) Palgat Plus (3M ESPE). PMID: 29262138 Bookshelf ID: NBK470480 Excerpt Impression materials are classified as either elastic or non-elastic based on mechanical properties. Material and methods: A questionnaire based survey was conducted among the dental practitioners of Makkah region of Saudi Arabia. 1 Composition and mixing ratios for commercial alginate impression materials. The aim of this survey was to integrate impression techniques evolved all over the years for fixed partial dentures and to know the techniques and materials which are used in the present day by the practitioners.
