Because alginate impression material reacts favorably to water, it produces accurate dental impressions even in the presence of saliva. An accurate impression of your teeth and gums will help your dentist recreate a model of your dental arch. This will then be used to customize the dental device.

What is the purpose of alginate impressions?

Alginate impression can be used for the fabrication of a primary cast in prosthodontics, study models in orthodontic, and duplication of casts. In one study, it was shown that alginate impressions could also be used as final impressions for indirect restorations with chamfer finish lines.

What are the advantages of alginate?

alginate is readily available, is ecofriendly and is relatively cheap to produce. This, together with several other advantages such as biocompatibility, biocompostability and nontoxicity, has led to the development of multiple alginate-based applications in the food and biomedical industries [19] (Figure 1).
