A dental impression is a three-dimensional negative imprint of your teeth and mouth. Dental impressions are widely used for fabricating mouth guards, retainers, whitening trays, crowns, veneers, bridges, and dentures.
Our experienced team at Dental Specialists of North Florida in Saint Augustine and Palm Coast, Florida, use dental impressions to provide comfortably-fitting dental restorations and orthodontic appliances.
In this article, we are sharing more information on what dental impressions are and their uses in dentistry.
Dental impressions are used to generate a near-perfect duplicate of your teeth, oral tissues, or both. They are taken using a horseshoe-shaped plastic or metal tray that comfortably fits into your mouth. The tray can be customized based on specific requirements.
There are three main types of dental impressions:
These are exact replicas of the patient's mouth that are often used for diagnosis, documentation of dental arches, and educational purposes.
The full features of the tooth architecture and supporting tissues are captured in final impressions. They're utilized to create accurate casts of the tooth structures. Crowns, bridges, dentures, and other restorations are made with the help of these impressions.
Bite registrations are used to capture the occlusal connection between the dental arches, which is important for fabricating maxillary and mandibular casts.
A liquid solution, such as alginate or polyvinyl siloxane, is placed in a U-shaped dish or tray that is appropriately fitted into the patient’s mouth to generate a dental impression. The material hardens once the tray is removed and is sent to a dental laboratory for further processing.
The trays come in a variety of shapes and sizes, including quadrant trays that cover half an arch and full trays that cover the entire maxillary or mandibular arch.
Dental impressions do not cause pain. However, some patients with a sensitive gag reflex may experience some discomfort. Dentists recommend you practice breathing through the nose during the procedure.
The duration of the entire process depends on when the imprint of the teeth is formed. Generally, it only takes a couple of minutes to get your dental impressions.
