About dust-free alginate
Dust-free alginate is alginate impression powder the maker labels dust-free; the filler in an alginate powder is mostly silica. Diatomaceous earth is the usual filler, and it also controls the fluidity and the consistency of the mix and leaves a smooth impression surface. A CDC report on dental laboratories states that exposure to respirable crystalline silica there can happen during procedures that make dust airborne, and it lists mixing powders among them.
An impression is a negative likeness of the teeth and the structures next to them, and an impression material is any substance used to make one. Alginate is the common name for irreversible hydrocolloid: a sol of alginic acid whose state is changed by an irreversible chemical reaction that forms insoluble calcium alginate. Alginates are salts of alginic acid, a polysaccharide extracted from the cell walls of brown algae. It is sold as a powder mixed with water, and once mixed it becomes a soft paste that is placed on the tray and taken to the mouth.
The powder holds the alginate salt, fillers that are mostly silica, calcium sulfate as the reactor, fluorides that speed the set, trisodium phosphate as the retarder, and colour and flavour additives. The FDA regulates impression material as a Class II device with special controls, and names alginate in the definition (21 CFR 872.3660). ISO 21563 is the international standard for hydrocolloid impression materials, covering agar and alginate as sold, and their labelling and instructions for use.
How the types on this shelf differ
- Alginate — The powder-and-water material itself, mixed in a bowl. One impression gives one plaster model.
- Dust-Free Alginate — Alginate powder the maker labels dust-free; what it sets into is alginate like the rest of the shelf.
- Alginate Alternative — A silicone, not a powder and water, so there is no bowl and no mixing by hand. It comes out of a cartridge through a mixing tip, pressed by a dispensing gun.
- Alginate Accessories — The bowl, the spatula and the measures, not the material.
The shelf also carries a reversible hydrocolloid, the other hydrocolloid family: a gel that is brought on by cooling and can be returned to the liquid state when the temperature is raised enough.
What to look at when choosing an alginate
Set speed and water: the setting time depends on the water-to-powder ratio, where more powder speeds the reaction, and on the temperature, where warmer water sets faster.
Mixing ratio: the ratio is proportioned by the maker, and it varies between makers, which is why one mix comes out thick and another thin.
Water quality: some water supplies carry enough minerals to affect the accuracy and the set, and distilled or demineralised water can be used instead.
The tray: the tray is chosen for the arch and is perforated, and an alginate adhesive can be used as well as the perforations to hold the material in the tray.
Time to the model: immediate pouring of an alginate impression gave the highest accuracy of the teeth and tissues in one study. Alginate impressions cannot be kept long, and a humid environment at 4 degrees Celsius can delay pouring.
