Benefits of Intraoral Scanners for Orthodontic Workflows

Intraoral scanners have transformed orthodontic workflows, offering a range of advantages that enhance both efficiency and accuracy. Let’s dive into the key benefits they bring to the table.

Improved Accuracy and Reduced Errors

Digital scanning technology provides highly precise measurements. Take the Trios 3 intraoral scanner, for instance – it achieves a scanning accuracy of 6.9 ± 0.9 µm and a precision of 4.5 ± 0.9 µm ^[2]. This level of detail ensures orthodontic appliances fit correctly on the first try. Compare this to traditional alginate impressions, which are prone to errors caused by material inconsistencies, capture techniques, and even stone expansion during casting ^[2]. Research shows that 67% of studies favour digital impressions over conventional methods in terms of accuracy ^[5]. Digital models not only meet clinically acceptable standards but also allow for immediate rescanning if any areas are incomplete, keeping measurement differences within 0.20 mm ^[2].

Faster Turnaround Times

Switching to a digital workflow cuts down the time between scanning and appliance delivery. Traditional methods involve multiple time-consuming steps, but digital scans can be sent to laboratories in minutes, eliminating shipping delays. This efficiency translates to fewer remakes as well. For instance, crown remakes due to margin issues drop by 40%, fit issues by 33%, and high occlusion problems by 27% ^[4].

Enhanced Patient Comfort

For patients, intraoral scanning offers a far more comfortable experience. It removes the need for traditional impression materials, which many find unpleasant due to their taste, smell, or texture. Studies confirm that patients prefer digital scanning for its sensory comfort [4, 8, 9]. The smaller, less intrusive scanner tips also help minimise gag reflex issues. While some systems still require a powder coating, ongoing advancements are reducing this inconvenience.

Seamless Laboratory Communication

Intraoral scanners make it easier for dental practices to collaborate with laboratories. Digital impressions can be uploaded to cloud-based platforms and shared instantly, allowing labs to begin work without delay. This streamlined process reduces the likelihood of errors during fabrication, as integrated software verifies scan data before production [13, 15]. Practitioners can also quickly address any scanning errors, ensuring the data sent to the lab is accurate from the start.

Advanced Treatment Planning Capabilities

Intraoral scanners do more than just streamline workflows – they also enhance treatment planning. By integrating with advanced software, these scanners allow for detailed visualisation, measurement, and simulation of treatment outcomes. Practitioners can assess distances, angles, and volumes with a precision that traditional models simply can’t match. Additionally, digital scans can be stored indefinitely without losing quality, providing a reliable record for long-term monitoring. They also support the creation of customised appliances through computer-aided design (CAD) software ^[3]. These features align perfectly with the growing adoption of digital tools in orthodontic practices across Australia.

How to Integrate Intraoral Scanners into Your Workflow

Incorporating intraoral scanners into your practice can streamline processes and improve patient care. Here’s how to make the transition effectively.
