Dental impressions produce a replica of your teeth and oral tissue. A metal or plastic horseshoe shaped tray is chosen to fit either the upper or lower teeth and gums comfortably.

A thick liquid material such as alginate or polyvinyl siloxane is dispensed into the tray. It is then placed onto either the upper or lower teeth so it covers the entire dental arch, including the roof of the mouth, for an upper impression, and the floor of the mouth and under the tongue for lower impression. After a preset amount of time, the material sets and becomes a solid rubber mass. The tray is removed from the mouth and is then sent to the clinic’s laboratory for further processing. Dental stone (plaster) is poured into the hardened impression and when set, a dental cast is produced.
