In recent years, digital dentistry has evolved to transform patient care, and at the forefront of this change is the intraoral scanner. These devices offer precision, speed, and a far more comfortable experience than traditional dental impressions.
But what is the function of a scanner in dentistry, and why does it matter to you as a patient, especially if you're considering treatments like Invisalign? Invisalign Toronto uses advanced iTero™ scanning technology to provide safe, efficient, and high-quality care. This article breaks down the practical roles scanners play in dental diagnostics and treatment, backed by clinical knowledge and patient-centered experience.
Understanding Dental Scanners: A Modern Innovation
A dental scanner—especially intraoral scanners—is a handheld digital tool to create accurate 3D images of a patient’s teeth and gums. Unlike old-school molds made with impression material, scanners are non-invasive, more hygienic, and allow real-time visualization of the mouth.
According to a study in the Journal of Dentistry (2021), digital impressions are significantly more accurate than conventional ones, reducing the likelihood of restoration errors and repeat appointments.
What Is the Function of Scanners in Dentistry?
Let’s take a closer look at the primary functions of dental scanners and how they improve treatment planning and outcomes.
Creating Accurate Digital Impressions
Scanners replace traditional physical molds by capturing precise digital impressions. These 3D models reflect the exact shape, contour, and spacing of teeth and surrounding tissue.
Traditional molds often distort due to human error or material shrinkage. Digital scans reduce inaccuracies and improve treatment precision, especially for procedures like Invisalign aligners, crowns, bridges, and veneers.
Improving Invisalign Treatment Accuracy
At Invisalign Toronto, intraoral scanners like the iTero Element™ are directly integrated into the Invisalign treatment workflow. These scans feed into ClinCheck® software, which designs your aligners and projects your tooth movement path.
A 2022 study published in Orthodontics & Craniofacial Research found that intraoral scanners significantly enhance the fit and performance of clear aligners, improving patient compliance and outcomes.
Enhancing Patient Comfort and Safety
Traditional impressions are uncomfortable and can trigger gag reflexes. Scanners, on the other hand, are:
Non-invasive
Quick (completed in 3–5 minutes)
Radiation-free (unlike X-rays)
Patients at our clinic often comment on how pain-free and smooth the scanning process is, especially compared to their previous dental visits elsewhere.
Reducing Appointment Time and Repeat Visits
If a traditional mold is faulty, the entire impression needs to be remade. With a scanner, dentists can rescan specific areas instantly, saving time and effort for both patients and clinicians.
This allows for quicker treatment planning and delivery of crowns, aligners, or night guards.
Real-Time Visualization and Education
Many scanners, like the iTero™, display real-time 3D models on a screen. Patients can see their teeth in detail, understand their dental issues, and visualize projected outcomes, such as how Invisalign can shift their smile.
Patients who are part of the process are more engaged and confident in their treatment decisions.
Supporting Restorative and Cosmetic Dentistry
Dental scanners assist with:
Fabricating crowns and bridges
Designing veneers and inlays
Preparing dental implant abutments
The digital files are securely shared with dental labs, reducing human error and speeding up turnaround time.
Digital Storage and Monitoring Over Time
Scans are stored digitally in patient records and can be compared across months or years. This helps monitor gum health, tooth wear, bite changes, and the progress of orthodontic treatment.
Transparent data over time improves communication and builds patient trust in the care being provided.
Are Dental Scans Safe?
Yes. Intraoral scanners do not emit radiation and are considered safe for all ages, including children and pregnant patients. They use optical or laser technology to capture images.
At Invisalign Toronto, we follow strict sterilization and safety protocols for every device, ensuring a hygienic, comfortable experience for every patient.
Types of Scanners Used in Modern Dentistry
Here are the industry-leading scanners commonly found in dental practices:
iTero Element™ – Preferred for Invisalign workflows
3Shape TRIOS® – Known for speed and color accuracy
CEREC Primescan® – Often used with in-office milling for same-day crowns
Medit i700 – A popular option for general restorative work
Benefits of Using Scanners at Invisalign Toronto
When you choose Invisalign Toronto, you get the advantage of:
Mess-free impressions: Digital scanners eliminate the need for traditional impression materials, which can be uncomfortable and messy. Patients no longer have to bite into gooey trays, making the experience more pleasant, especially for those with gag reflex sensitivity.
Faster results and fewer appointments: Scans are completed in minutes and can be transmitted instantly to labs or Invisalign’s planning system. This reduces waiting time for aligners or restorations and helps minimize the visits needed for treatment adjustments or retakes.
Greater transparency in treatment: With real-time 3D visuals, patients can see what the dentist sees. This improves communication and allows for a better understanding of conditions and procedures, helping patients make more informed decisions about their dental care.
Comfortable, noninvasive scans: Unlike traditional impressions, which may cause discomfort or anxiety, scanners are handheld, small, and gentle. They don’t involve any pressure or bulky materials, making them ideal for children, seniors, and patients with dental anxiety.
Enhanced aligner fit and performance: Accurate scans ensure that Invisalign aligners are custom-made to fit each patient’s unique dental anatomy. This improves the effectiveness of the treatment, reduces discomfort, and lowers the chances of needing mid-treatment refinements or adjustments.
Our dental professionals have extensive training in using the iTero™ scanner, ensuring accurate diagnostics and Invisalign planning tailored to your unique smile.
