Dental Materials, Impression
Definition : Dental materials designed to make an accurate negative reproduction of a given area of the oral cavity. These dental materials usually are inserted into the mouth while they are soft by means of a customized tray known as a stock tray. The materials then become solid in a few minutes and when removed from the mouth retain the shape of hard (e.g., teeth) and/or soft (e.g., tongue, cheeks, gums) tissues. Dental impression materials unite into a solid mass without adhering to the oral tissues and most of them have dimensional stability. They flow at temperatures which do not injure the oral tissue. Dental impression materials include alginate, polyether and vinyl polysiloxane. They are used in dental offices and provide models for study and for production of restorative prosthetic dentures.
