  2. Alginic acid - Wikipedia

    en.wikipedia.org/wiki/Alginic_acid

    Alginate is used as an ingredient in various pharmaceutical preparations, such as Gaviscon, in which it combines with bicarbonate to inhibit gastroesophageal reflux. [citation needed] Sodium alginate is used as an impression-making material in dentistry, prosthetics, lifecasting, and for creating positives for small-scale casting. [citation needed]

  3. Dental impression - Wikipedia

    en.wikipedia.org/wiki/Dental_impression

    An impression body, made from alginate impression material. A custom dental model or plaster cast.. A dental impression is a negative imprint of hard and soft tissues in the mouth from which a positive reproduction, such as a cast or model, can be formed.

  4. Lifecasting - Wikipedia

    en.wikipedia.org/wiki/Lifecasting

    A variety of materials can be used for both the molding and casting stages of the lifecasting process. For moulding, alginate and plaster bandages are the most popular materials. Different alginate formulas are available with different setting times and working properties. Choosing the correct formula can make the job much easier.

  5. Dental material - Wikipedia

    en.wikipedia.org/wiki/Dental_material

    Impression materials are designed to be liquid or semi-solid when first mixed, then set hard in a few minutes, leaving imprints of oral structures. Common dental impression materials include sodium alginate, polyether and silicones. Historically, plaster of Paris, zinc oxide eugenol and agar were used.

  6. Calcium alginate - Wikipedia

    en.wikipedia.org/wiki/Calcium_alginate

    Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture.

    Additionally, these alginate-based bioinks can be blended with other materials such as nanocellulose for application in tissues such as cartilage. [8] Since fast gelation leads to good printability, bioprinting mainly utilizes alginate, modified alginate alone or alginate blended with other biomaterials.

  8. Bite registration - Wikipedia

    en.wikipedia.org/wiki/Bite_registration

    Plaster of Paris is a plaster material used for casting impressions, impression plaster for bite registration consists of plaster of Paris with additives, more water can be added to the powder than with the casting material to provide more flow for taking the impression. [16] These additives hasten the setting time and reduce setting expansion ...

  9. Hydrogel fiber - Wikipedia

    en.wikipedia.org/wiki/Hydrogel_Fiber

    One of the most commonly used fiber production methods is the crosslinking of sodium alginate by CaCl 2, where the formed calcium alginate will act as the crosslinking point to link the alginate chains together to form the network and solidified the polymer. Afterward, this alginate hydrogel fiber can be used as a template for the ...
