An impression results in the imprint of teeth and gums, which can be used to make a mold of the dentition and gums.The creation of dental impressions is vital to build dentures, inlays, casts, and implants. Orthodontists, general dentists, prosthodontists, and oral & maxillofacial surgeons use dental impressions on a daily basis.
This is a very safe process that has been used for centuries. The dental impression tray pictured below is currently housed in the Science Museum of London. It was used in France between 1830 and 1850.
