What is an Intraoral Scanner

An intraoral scanner, also known as an IOS, is a scanning device that takes a direct optical impression of the patient’s mouth. As with other 3D scanners, they project a laser or structured light onto the object being scanned. A scanning software produces images of the teeth, along with images that display the projected results of the treatment with a 3D model of the patient’s mouth.

The first versions of this technology emerged in the 1980s, but the technology has advanced greatly since then. The typical model consists of the wand the practitioner uses to capture images inside the patient’s mouth that connects to a monitor that displays the image.

Why People may Prefer Intraoral Scanning Over Other Methods

Intraoral scanning enhances the treatment process for patients considering altering or repairing their smile. Along with not requiring our team to take a mold of the teeth, the scanner can provide enhanced detail of the images. While effective, traditional methods without a scanner have an increased margin for error.

This type of digital dentistry allows our prosthodontist and team to ensure patients have the highest chance at achieving their ideal smile. Also with the traditional method, over 60% of impressions sent to labs are described as unacceptable. Even if the lab can fix the mistakes, send them back to be redone, or try to work with what they have, it costs everyone more time and increases the risk of ending up with an ill-fitting and inferior product. Intraoral scanning speeds up treatment time and reduces errors, increasing patient satisfaction.

Frequently Asked Questions About Intraoral Scanners

How does intraoral scanning benefit the patient?

Comfort and less time in the dentist chair are probably the biggest selling points for patients when it comes to intraoral scanning. Also, the patient can see the dentist craft the plan for dental work right on the 3D model on the screen. This type of technology helps make same-day smile designing possible. The accuracy the intraoral scan offers increases a patient’s confidence in the outcome of the work they are having done.

What is the most common way dentists take impressions?

The traditional impression-taking method is still the most common way. A recent article on Oralhealthgroup.com reports that less than 10% of North American dentists use intraoral scanning. Intraoral scanning has only been around for a few decades and is still very new. As with any change, things take time.

Should I be worried about radiation exposure with an intraoral scanner?

Intraoral scanners use visible light radiation and not X-ray radiation. The energy levels of the electromagnetic radiation from this light is so low there is no known risk to biological tissues. Intraoral scanners pose about as much radiation risk as getting your picture taken with a smartphone.

Is there anything the patient should be aware of when being prepared to have a digital impression taken?

Having a digital impression taken is less work for the patient. Some digital scanners require the teeth to be sprayed with a powder to get an accurate recording. However, this powder is safe for humans and not a big issue for patients. Our practice’s intraoral scanner does not require a powder coating before scanning.

Is an intraoral scanner safe for a pregnant woman and her baby?

This is a common concern with new technologies. Yes, the intraoral scanner is safe for pregnant women. As mentioned above, the intraoral scanner poses about as much radiation risk as having your picture taken with a smartphone.

How long does a full-mouth intraoral scan take?

A full mouth scan with an intraoral scanner takes about 5 minutes. It is not lightning fast. Still, it is likely faster and more comfortable than traditional impression taking. Following the scan, we will go over the possible treatment options, and more information the patient might need.
