If you’ve had traditional dental impressions taken before, you remember the experience. A tray loaded with thick, cold, putty-like material pressed into your mouth. Hold still for a couple of minutes. Try not to gag. Hope it comes out clean.
It’s not the worst thing in the world, but it’s not comfortable either. And for patients with a sensitive gag reflex, it can be genuinely difficult.
iTero digital scanning does the same job without any of that.
What an Impression Is Actually For
Before understanding why digital scanning is better, it helps to understand what an impression is doing in the first place.
An impression captures the shape of your teeth and gums in three dimensions so that dental restorations, aligners, retainers, and other appliances can be made to fit your specific mouth accurately. The accuracy of the impression directly affects how well the finished product fits.
Physical impressions capture this information by pressing a pliable material against the teeth and letting it set around them. Digital scanning captures it by moving a handheld wand around the mouth while an infrared camera takes thousands of measurements per second. The result is a precise, interactive 3D model on screen in real time.
What the iTero Scan Experience Actually Feels Like
The iTero scanner is a small wand about the size of an electric toothbrush handle. The hygienist or dentist moves it slowly around the teeth, and the 3D model builds itself on the screen as they go. There’s nothing in your mouth except the wand itself, which sits near the teeth without pressing on the soft tissue.
Most scans take two to five minutes. There’s no waiting for material to set, no cleanup, and no risk of the impression distorting when it’s removed. For patients who struggled with a gag reflex during traditional impressions, the difference is significant.
What Wave Dentistry Uses iTero Scanning For
At Wave Dentistry in White Rock, the iTero scanner is part of the oral health scanning workflow and supports a range of treatments.
Invisalign
This is probably the most well-known application. Invisalign requires a highly accurate 3D model of the teeth to design the aligner series. iTero integrates directly with Invisalign’s ClinCheck software, so the scan can be used immediately for treatment planning without a conversion step. The digital model shows the predicted tooth movement at each stage of treatment, which gives patients a clear picture of what the plan looks like before they commit.
Crowns and restorations
The same precision that makes iTero useful for aligner planning makes it useful for crown fabrication. A digital scan of the prepared tooth feeds directly into the CAD/CAM workflow that produces Wave Dentistry’s same-day crowns, improving fit accuracy compared to traditional impression methods.
Monitoring changes over time
Because each scan is stored digitally, repeat scans over time can be compared precisely. This lets Dr. Gaudet track subtle changes in tooth wear, gum tissue, or bite relationships that might not be obvious in a single examination. Over years of care, this kind of longitudinal record is genuinely useful.
Oral health reporting
We uses digital scanning as part of its broader oral health scanning service, which gives patients a detailed picture of their dental health that goes beyond what a clinical exam alone reveals.
Why Accuracy Matters More Than Convenience
The patient experience of iTero scanning is better than traditional impressions. That’s straightforward. But the accuracy benefit is the more clinically significant part.
When a crown is made from a digital scan, the fit is determined entirely by the precision of the 3D model. Physical impressions can distort in small but meaningful ways during setting, removal, or transit to a dental lab. A well-executed digital scan doesn’t have those failure modes.
For Invisalign, a more accurate model means aligners that fit more precisely at each stage, which affects how well the teeth track the treatment plan. Cases built on accurate scans tend to require fewer refinements.
This is the kind of technology investment that doesn’t show up dramatically in a single appointment but compounds over the course of a treatment. It’s part of why Wave Dentistry positions itself around modern, precise care rather than the cheapest option available.
What to Expect at an Appointment That Includes an iTero Scan
The scan typically happens at the beginning of the appointment, before any clinical work. You’ll be asked to open your mouth, and the hygienist or White Rock dentist will move the wand around systematically. You can watch the model build on screen as they go.
The scan is exported immediately. For Invisalign cases, it goes to the planning software. For crown cases, it feeds into the design workflow. For monitoring purposes, it’s saved to your patient record and compared at future appointments.
There’s no special preparation required and nothing to do afterward.
