Abstract
Gypsum has been used for many years as a dental impression, modeling, and bite recording material. Availability, price, mechanical and physical properties, such as dimensional stability, have made gypsum as the most popular dental modeling and investment materials. The physical and chemical structures of gypsum particles, as well as their manipulation characteristics, play an important role in their properties. This chapter aims to provide the dental professions and students with basic and practical information on currently used dental modeling and investment materials covering desirable qualities, composition, production, and applications of different types of gypsum products. Also, the setting reaction and setting expansion of gypsum products as well as manipulation of gypsum products will be discussed. Finally, advanced technologies and their application in dental die production will be explored.
