Digital Impressions (also known as 3-D intraoral scanning) are the latest technology in capturing a replica of the mouth. By using a wand-like tool connected to a computer and advanced software, a dentist can create a virtual model of the hard and soft tissues in the mouth. These replicas are more accurate than a mold, and can be used for a variety of needs. After taking a scan of the mouth, a dentist can immediately send the digital impression to a lab where dentures, crowns, bridges, and retainers can be made quickly and accurately.
