Many dental treatments and devices are specially designed to fit into the mouth naturally. To get these impressions, they use a material known as alginate. Alginate impression material Can be: immersed in an appropriate disinfectant for up to 30 minutes without distorting An irreversible hydrocolloid cannot: reverse from a gel to a sol because a chemical reaction prevents it The elastic recovery (or rebound) of alginate impression material can be increased by which one of the following? It solidifies into an elastic mass capable of producing a negative reproduction of the oral cavity (an impression) (Poling et al. impression can be removed easily & has pleasant taste & odor, so comfortable for the patient.

The patients general oral health is fair. January 5, 2012 by Dr. Varun Pandula 1 Comment. 2017). Even if a lot of rubber base impression materials with good physical properties was used to take impressions, the alginate material was able to prove its usefulness and has been a staple of most dental practices the world. Alginate is an elastic hydrocolloid dental impression materials to obtain negative reproduction of oral mucosa such as to record soft-tissue and occlusal relationships. Before The best way to alter gelation time is to change the temperature of the water in the mix. In: Crawford HB, Williams J (eds) Handbook of water-soluble gums and resins. I.

Your dentist will start by cleaning the teeth to remove any debris and allow the mouth to partially dry. No adverse effects observed in working time, setting time, and surface detail reproduction of alginate impressions. Alginates possesses numerous vital properties such as hydrophilicity, ability to record finer details, elastic recovery and inexpensive; makes this material widely used in dentistry. Dent Res J (Isfahan) 2013;10:6573. 1991;4:3827. Alginate is an anionic polysaccharide mainly found in brown algae.
