For decades, capturing dental impressions meant biting into trays filled with thick impression material and waiting several minutes for it to set. While effective, traditional impressions can be uncomfortable, messy, and prone to small inaccuracies. Today, advances in digital dentistry have introduced a more modern alternative: intraoral scanning systems such as the iTero scanner. These devices capture highly detailed digital impressions of teeth and oral structures, transforming how dentists plan treatments and fabricate restorations.
A More Comfortable Patient Experience
One of the most immediate advantages of iTero scanning is improved patient comfort. Traditional impressions often trigger gag reflexes, require multiple retakes, and can leave patients with an unpleasant taste. Digital scanning eliminates impression trays altogether. Instead, a small handheld scanner moves around the mouth, capturing thousands of images per second to create a precise 3D model of the teeth. This process is quicker, cleaner, and far more comfortable for patients.
Greater Accuracy and Precision
Accuracy is critical when creating dental restorations such as crowns, bridges, or orthodontic aligners. Digital intraoral scanners were developed specifically to address the limitations of conventional impression techniques, which can be affected by material distortion, bubbles, or human error during handling. Modern intraoral scanners produce highly detailed digital models, improving the precision of dental restorations and helping ensure a better fit.
Research also highlights that digital impressions provide reliable trueness and precision, two key measures of accuracy that directly affect the performance and longevity of restorations. When scans are accurate, dental laboratories can fabricate restorations that require fewer adjustments and fewer repeat appointments.
Faster Workflow and Fewer Appointments
Digital impressions streamline the entire dental workflow. With traditional impressions, physical molds must be disinfected, packaged, and shipped to a dental laboratory. iTero scans, however, are sent instantly to the lab in digital form, eliminating shipping delays and reducing turnaround times.
In many cases, dentists can also immediately review the scan on screen and verify that all necessary areas were captured accurately. If adjustments are needed, they can simply rescan the area rather than repeating the entire impression process. This efficiency often means fewer appointments and faster treatment completion.
Improved Treatment Planning
Another major advantage of digital scanning is the ability to visualize treatment outcomes in real time. iTero scanners allow dentists to display detailed 3D images of the patient’s teeth on a screen, helping patients better understand their oral health and treatment options. For orthodontic treatments such as clear aligners, simulations can even demonstrate how teeth may move over time, allowing patients to see potential results before treatment begins..
A Key Technology in Modern Digital Dentistry
Intraoral scanners have become an essential component of modern digital dentistry, supporting procedures ranging from crowns and bridges to implants and orthodontic treatments. As digital technologies continue to evolve, they are improving clinical precision, reducing errors, and enhancing patient experiences across dental care. By replacing traditional impression materials with accurate digital scans, technologies like the iTero scanner represent a significant step forward in dentistry, offering a faster, cleaner, and more comfortable way to capture the information needed to create high-quality restorations.
