Adopting an intraoral scanner is a practical entry point into digital dentistry. In suitable workflows, it can help reduce discomfort associated with conventional impressions, streamline clinical procedures, enhance chairside communication, and simplify the transfer of digital case data to compatible dental laboratories. Whether you are expanding into digital restorative dentistry, orthodontic workflows, digital models, or selected implant-restorative cases, choosing the right intraoral scanner can help improve daily practice efficiency.
Below, we break down how intraoral scanning works, what it can do for your clinic, which factors truly matter when choosing a scanner, and whether a system like the Owandy IOS may be the right fit for your practice.
What Is an Intraoral Scanner, and How Does It Work?
An intraoral scanner is a handheld digital device that captures 3D data of the teeth and oral structures. Instead of creating a physical mold, it uses optical imaging and software to build a digital 3D model that can be viewed, analyzed, stored, and transferred within a digital dental workflow.
Most intraoral scanners follow the same fundamental workflow. First, the scanner projects light onto the teeth and captures the reflected signals with optical sensors. As you move the handpiece across the mouth, the software continuously processes that captured information. This real-time processing turns the optical data into a usable 3D representation while you scan.
As the capture progresses, the software builds the model piece by piece, allowing clinicians to review the scan almost immediately. If any areas are missing or unclear, the scan can often be corrected with targeted re-scans before you move on to the next step. The final output is a digital 3D file that can support clinical assessment, treatment planning, CAD/CAM design, orthodontic workflows, and collaboration with a compatible dental laboratory.
What Can You Do With an Intraoral Scanner?
In a modern dental practice, an intraoral scanner is more than a digital alternative to conventional impressions. It captures 3D surface data from teeth, visible soft tissues, and bite relationships in appropriate workflows.
| Application | How an Intraoral Scanner Can Help |
| Restorative dentistry | Capture digital 3D data for crowns, bridges, veneers, and other restorative workflows |
| Orthodontics | Create digital models for assessment, treatment planning, and aligner workflows |
| Implant dentistry | Support selected implant planning and restorative workflows |
| Digital models | Create, review, and store 3D models digitally |
| Occlusion | Capture digital bite relationships in appropriate workflows |
| Patient communication | Show patients a 3D view of their teeth |
| Lab collaboration | Transfer digital scan data to compatible laboratory workflows |
Adopting an intraoral scanner does not just swap out one clinical technique for another — it fundamentally reshapes how your clinical team spends time during an appointment. Moving from a physical process to an end-to-end digital workflow brings four distinct operational shifts chairside:
- See the data immediately: During scanning, you can review the capture in real time, identify missing areas, and rescan only where needed.
- Share digital data more easily: Compatible scan files can be delivered to a dental lab without producing and shipping physical models or impressions.
- Improve patient communication: A clear 3D view can help patients understand what’s being planned and why.
-
Reduce manual steps: Digital workflows can reduce certain processes involved in traditional impression handling, model preparation, transport, and data entry.
The core value is simple: a practical intraoral scanner should support the cases you already do, then help your team work faster and more predictably with fewer rework steps.
What Really Matters When Choosing an Intraoral Scanner?
When comparing intraoral scanners, do not choose based on a single claim such as “fast scanning,” “high accuracy,” or “wireless freedom.” A scanner becomes valuable only when it improves the full clinical workflow: patient experience, usable scan data, team adoption, laboratory communication, and long-term cost control.
1. Patient Experience
Intraoral scanning can be more comfortable than conventional impressions because it avoids impression trays and impression material. Patients who have a strong gag reflex or previous negative experiences may particularly appreciate the difference. However, comfort still depends on tip size, scanning speed, posterior access, and how often the operator needs to rescan.
2. Clinical Accuracy
Do not compare scanners by micron numbers alone. Accuracy can vary with the scanner, scanning strategy, operator technique, scan area, preparation geometry, and clinical conditions.
Look at how the scanner performs in your typical cases—single crowns, veneers, bridges, orthodontics, implants, or full-arch scanning. Consider full-arch performance, scan stability, margin capture, and how easily the team can complete a usable scan. The key question: Can your team consistently capture lab-ready data for the cases you perform most often?
3. Real-Time Review
One advantage of digital scanning is immediate model review. Missing or incomplete areas can often be identified and rescanned while the patient is still in the chair. Look for software that makes scan gaps easy to identify and allows localized rescanning without restarting the entire case.
4. Workflow Speed
A 20-second full-arch scan does not mean a 20-second appointment. The real workflow also includes review, rescanning, bite capture, processing, export, and laboratory transfer.
A useful scanner should make each step simple and predictable. Digital files can also reduce or remove the physical shipping of conventional impressions, although overall turnaround still depends on scan quality, laboratory capacity, and case complexity.
5. Ergonomics and Connectivity
Handpiece weight, grip, tip size, posterior access, cable management, battery life, and computer setup all affect daily usability. Wired and wireless models each have advantages, so the right choice depends on how your operatories are organized and how your clinicians prefer to work.
6. Software and Lab Compatibility
Before purchasing, confirm compatibility with your preferred laboratory and CAD/CAM workflow. Check supported formats such as STL, PLY, or OBJ, as well as export restrictions, cloud requirements, and subscription fees.
An open workflow can provide more flexibility, but always confirm that your actual laboratory can receive and use the files you plan to send.
