What is a Digital Impression?

Digital impressions are currently revolutionizing the way dentists create dental restorations for patients. A digital impression is a virtual scan of your teeth that makes a map of them. Dentists can create a 3d-virtual, computer-generated model of the hard and soft tissues of the mouth using lasers and other optical scanning devices. This digital model enables dentists to view patients’ teeth on a computer screen. Rather than using a mirror, a mould, or an X-ray, as these are the traditional methods. After taking an impression, a dentist can immediately send the digital impression to a lab instantly and accurately create dentures, crowns, bridges, and other restoration.

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.

Traditional Dental putty Impression

During this procedure, your dentist dispenses a putty-like dental impression material into plastic or metal trays. Next, they’ll place the trays over your teeth. After a minute or two, the dental impression material sets and hardens. Finally, your healthcare provider removes the trays (and impression material) from your mouth. Your impressions are then sent to a dental laboratory. There, a technician will pour stone into your dental impressions to create a cast of your mouth.

Digital dental impressions

Many dental offices now have the ability to take digital dental impressions. During this procedure, your healthcare provider uses a digital handheld wand to capture thousands of pictures of your teeth and gums. As your healthcare provider passes the wand over your teeth, images of your mouth will come up on a computer screen.

Next, the computer software will stitch the images together, creating a digital, 3D representation of your dental arches. There’s no need for putty when taking digital dental impressions. Your healthcare provider will then electronically deliver your photo files to a dental lab. There, a technician will begin working on your case.

How are Digital Impressions created?

A digital impression can be captured by a series of digital photographs or by a digital video. Both methods capture precise measurements in the mouth and send numerous small images that are immediately stitched together by the digital impression machine’s software to form a precise map of your mouth. Most of the time patients can view these images on a chair-side monitor.

An impression is a metric used to quantify the number of digital views or engagements of a piece of content, usually an advertisement, digital post, or a web page. Impressions are also referred to as an “ad view.” They are used in online advertising, which often pays on a per-impression basis.

What are the 3 types of dental impressions?

  1. Preliminary impressions: They are used for diagnostic purposes, or as the initial step in the process of fabrication (making) of different prostheses, including crowns and dentures. They’re often made at your initial office visit. They provide your dentist with a visual aid so they can plan your treatment.
  2. Final impressions: These are sent to a dental laboratory for the fabrication of dental restorations or appliances. These may include crowns, bridges, dentures, retainers and more.
  3. Bite registration: This type of impression shows the way your upper and lower teeth fit together.

Step-by-Step process for Dental Impression:

Step 1: Dentists prepare the patient’s teeth for scans by clearing the area of blood and saliva and dusting the teeth with specially formulated titanium dioxide powder (if the scanner is not powder-free)

2nd Step: They capture a series of digital images or videos using an intra-oral wand that is inserted into the patient’s mouth and moved around the affected area

Step 3: Impression software pieces the images or videos together within seconds and displays the impression image on a chair-side screen

4th Step: Dentists review the digital images and verify the accuracy of the scan

Step 5: The digital impressions are sent to the dental laboratory where the patient’s restorations such as crowns, dentures, and bridges are created

Advantages of Digital Impression

More Efficient

Digital dental scans eliminate the need to pour models, send them to a lab, and wait for the lab technician to make your custom restoration. Instead, milling technology is used to convert the scan into something like a customized dental crown during the same appointment. Your permanent restoration will be ready to fix into place, eliminating the need for a second appointment or wearing a temporary “cap” for two weeks.

More Comfortable

Most people dislike taking traditional dental impressions. Traditional impressions can get in the way of a healthier smile if you are claustrophobic, have a sensitive gag reflex, or don’t like things in your mouth. Digital dental impressions do not require sticky alginate, and there are no bulky trays to fit inside the mouth. The thin wand is systematically scanned across your teeth to capture images of every angle of your tooth.

Extremely Accurate

You may wonder how accurate a digital scan of your teeth would be compared to a physical impression. The precision is exceptional and eliminates the possibility of human error during lab processes, resulting in a highly accurate restoration that fits and feels great from the moment it is placed inside the mouth.
