Which material is commonly utilized for making dental casts?

The most commonly utilized material for making dental casts is alginate. Alginate is a hydrocolloid material derived from seaweed and is favored in dentistry due to its ease of use, quick setting time, and ability to capture fine details in dental impressions. It is nondisruptive to soft tissues and provides an accurate representation of the dental and surrounding structures.

Alginate impressions are generally used for preliminary models, orthodontic applications, and for creating custom trays because they are economical and can be easily mixed and manipulated. The setting properties of alginate allow for a convenient working time, and while it may not be as precise as some other materials for definitive casts, its benefits in various clinical situations make it a go-to choice in dental practices.

Polyether and silicone are also used for impressions but typically in more specialized cases, such as for precise, detailed cases or for applications requiring rigidity. Glycerin, while used in some dental procedures, does not serve the purpose of forming casts or impressions. Therefore, alginate is the most commonly selected material for the creation of dental casts in everyday dental practice.
