Intraoral dental 3D scanners are small handheld scanners that go directly into the patient’s mouth to examine the inside as well as to scan the teeth directly. They are significantly faster than impressions as the scans can be processed immediately, meaning they can be used to skip the impression stage.
Dental impressions are now very common and they are used for various dental purposes. These impressions may be used in creating mouth guards, retainers, accurate models, whitening trays, crowns, veneers, bridges, dentures, among others.
