If you’ve ever had dental impressions taken the old-fashioned way, you probably remember it. Bulky trays, sticky impression material, and a process that can feel uncomfortable—especially for anyone with a sensitive gag reflex. The good news is that modern dentistry has a better option.

At Northwest Chicago Dental Associates, we use the iTero digital scanner to capture highly accurate 3D images of your teeth without the mess. Digital impressions help support better-fitting restorations, smoother Invisalign planning, and a more comfortable patient experience from start to finish.

What Is the iTero Digital Scanner?

The iTero digital scanner is an advanced imaging device that allows your dentist to capture a detailed 3D model of your teeth and bite. Instead of using traditional impression material (the “gooey molds”), iTero uses a small handheld wand to scan your mouth and create a digital impression in real time.

The result is a highly accurate digital model that can be used for many common dental procedures, including Invisalign clear aligners, crowns, bridges, veneers, and more.

How iTero Digital Scanning Works (Step-by-Step)

Digital scanning is simple and patient-friendly. Here’s what you can expect during your iTero scan:

1) We gently guide the scanner wand around your teeth

2) The scanner captures thousands of images in seconds

3) Those images are instantly converted into a 3D digital model

4) Your dentist reviews the scan for accuracy and planning

5) The scan is used to design aligners or restorations, depending on your treatment

There are no trays, no waiting for impression material to set, and no unpleasant taste. It’s a straightforward experience that helps save time while improving results.

Why Patients Prefer Digital Impressions Over Traditional Molds

Traditional impressions are still used in some practices, but digital scanning has become the preferred approach for many patients because of comfort and accuracy.

More comfort during your visit

One of the biggest advantages is comfort. The iTero scanner eliminates bulky trays and impression material, which can be difficult for patients who feel claustrophobic, have anxiety during dental visits, or have a strong gag reflex.

Faster appointments

Digital scanning typically takes just a few minutes. There’s no need to wait for material to harden, no guesswork, and fewer retakes—so your appointment can be more efficient.

More accurate results

Accuracy matters in dentistry. A precise digital scan helps support a better fit for crowns, veneers, and other restorations. It also improves treatment planning for Invisalign and other cosmetic dentistry procedures.

Fewer retakes and adjustments

Traditional molds can sometimes distort or tear, requiring a redo. Digital impressions are captured and verified in real time, reducing the chances of needing to repeat the process.

What Can the iTero Scanner Be Used For?

The iTero digital scanner is a versatile tool that supports both cosmetic and restorative dentistry. Depending on your needs, it may be used for:

• Invisalign clear aligner planning
• Crowns and bridges
• Veneers
• Dental implants (planning and restorations)
• Bite evaluation and treatment planning
• Retainers and nightguards (when recommended)

Because the scan creates a detailed 3D model, it can help your dentist make more informed decisions and design more precise dental solutions.

iTero + Invisalign: A Better Way to Plan Clear Aligner Treatment

If you’re considering Invisalign, digital scanning is a major improvement over traditional impressions. Invisalign treatment depends on the accuracy of the initial model of your teeth. The more precise the scan, the more accurate the aligner plan can be.

With iTero scanning, your dentist can capture a detailed digital impression that supports predictable tooth movement planning and a smoother aligner experience. When needed, digital scans can also support refinements by identifying subtle changes in tooth alignment over time.

iTero Scan vs Traditional Dental Impressions: What’s the Difference?

Here’s a quick comparison between iTero digital scanning and traditional molds:

Comfort: iTero is typically easier and cleaner for patients

Accuracy: Digital scans reduce common distortion issues

Speed: Digital scanning is usually faster overall

Retakes: Digital impressions are less likely to need repeating

Experience: No messy material, no tray pressure, no unpleasant taste

For many patients, the difference is immediate. Digital scanning helps make the appointment feel easier and more modern.

What to Expect During Your iTero Scan Appointment

Most iTero scans are completed quickly. During your appointment, you can expect:

• A brief explanation of the scanning process
• Gentle scanning of your upper and lower teeth
• Bite scanning to confirm how your teeth come together
• Review of the digital model with your dentist

If the scan is being used for Invisalign, crowns, or veneers, your dentist will explain the next steps, including treatment recommendations and scheduling.

Why Digital Dental Technology Matters for Your Results

When patients think about dental technology, it’s easy to focus only on convenience. But the real value is that digital scanning helps improve precision. That precision can support better clinical outcomes, including restorations that fit more naturally and aligner plans that are more predictable.

Whether you’re improving your smile cosmetically or repairing damaged teeth, using modern tools like iTero helps your dental team plan and deliver results with more confidence.
