Auxiliary Dental Materials

3-7

Let’s talk about auxiliary dental materials. One example is acid etching your teeth before putting a crown. Acid etching in dentistry is an effective way to bond different types of restorations to enamel or dentin.

The second example of auxiliary dental material is impression materials. Alginate is one of the most widely used dental impression materials so far. Alginate became so popular due to the following advantages as can be easily prepared and manipulated, the setting time can be controlled and they provide high accuracy if properly handled; and they are cheap. However, their disadvantages include they have low tear strength and they do not transfer as much surface detail as gypsum dies.

Dental plaster, dental stone, high-strength dental stone, and casting investment are gypsum products. They are supplied as hemihydrates powder that is produced by heating ground gypsum particles. When mixed with water the mixture reverses the reaction back to gypsum.
