Gents, I’m an orthodontist. We do full mouth digital scans all day long for patients that we will be treating with Invisalign. We also scan our “braces cases” for study models/diagnostic models. Done correctly, digital scans can be way more accurate than impressions. There are many different types of impression materials. Once removed from the mouth, some are more stable than others. Some materials start to distort soon after removal from the mouth and need to be poured up with the dental stone to make a model of the teeth ASAP. Polyvinyl solaxane materials, which are used for crown and bridge impressions, are very stable and have served the profession well for many years. It is still used by many practitioners. This material does not need to be poured up immediately. Digital scanners are also used by many and are extremely accurate. Almost every orthodontist has a digital scanner now days. All of our appliances fit very well. Much better than when we were using PVS impressions. Remakes are a thing of the past for us. The appliances that we get back from our lab fit perfectly. The scanner that we use is the itero element 2. Check it out online. It’s pretty cool. We can perform a full mouth scan in approximately 5 minutes. It is received by the lab instantly once we hit the send button. Many patients are very apprehensive about having impressions taken thinking that it will make them gag, or worse throw up. Patients love the scanner vs. having to have an impression taken. Digital scanners are here to stay and the technology is getting better and better. I can’t imagine having to practice without a scanner.
