In the wave of digital dentistry, the intraoral scanner has become an essential tool for taking impressions in the clinic. Facing a wide array of brands and models, plus constant software updates, how do you select the right intraoral scanner for your practice?
01 Clinical Essentials
Different restorative fields place different emphasis on accuracy, functions, and software modules. First determine your primary clinical scenarios to avoid over- or under-specified features. Analyze requirements based on the main restoration types and patient demographics in your clinic.
Clarify Clinical Restoration Needs
① Orthodontics: Prioritize scanning speed, patient comfort, tooth segmentation, and orthodontic treatment simulation.
② Fixed restorations: Accurate capture of restoration margins, occlusion, and interproximal contacts; balanced precision and efficiency with stability in moist and restricted-visibility environments.
③ Implant restorations: Multi-source data fusion capability, cross-arch accuracy, precise capture of implant scan bodies and peri-implant soft-tissue cuff height.
④ Full-arch edentulous restorations: Maintained accuracy over large scanning ranges, soft-tissue adaptability, and jaw relation recording.
Consider Doctor-Patient Communication Functions The ability to display real-time scan data to patients, point out issues, and discuss treatment plans together allows patients to understand and accept the final outcome more quickly and conveniently. This is far more intuitive than abstract verbal descriptions and greatly builds trust.
02 Scanning Technology Performance
Scanner Accuracy and Speed Scanning speed mainly depends on hardware capability and AI implementation in the software. Speed directly affects patient experience and operational efficiency, including single-scan time, full-arch total time, and real-time rendering smoothness. Fast, reliable scanning is essential for challenging clinical situations.
Accuracy varies by brand technology and application scenario. For single-tooth or simple restorations, accuracy typically reaches 10-20 μm; some high-end devices achieve 5-10 μm, sufficient for veneers, inlays, and single crowns. For multi-tooth or complex cases (full-arch scans, multiple implants, or complex fixed bridges), accuracy usually falls in the 15-30 μm range. Errors increase slightly due to multiple teeth and complex anatomy but remain clinically acceptable. In implant-specific scenarios involving subgingival soft tissue or scan bodies, accuracy may drop to 20-50 μm, mainly influenced by the oral environment (saliva, soft-tissue interference) and scanning depth. Optimized technology and technique can still ensure restoration fit.
Scanner Resolution and Detail Capture Resolution and detail-capturing ability form the physical foundation of clinical value. High resolution sharply captures the morphology of preparation margins, the subtle relationship between the cervical margin and gingiva, cusp slopes and groove depth, as well as surface stains, discolorations, and fine cracks. A bright, realistic rendering of the scan data is highly desirable.
Scanning Depth of Field and Ease of Use Depth of field refers to the longitudinal working range in which the scanner tip can clearly capture tooth or tissue surface details without frequent forward-backward distance adjustments. A large depth of field allows continuous effective data capture even when patient tongue or cheek interference causes slight distance changes during scanning of complex posterior areas, buccal corridors, or gingival sulci. A shallow depth of field demands greater operator stability; in confined spaces, defocus easily interrupts the workflow, requiring repositioning, prolonging scan time, and increasing patient discomfort.
03 Software and Ecosystem
The accompanying software should feature a simple, intuitive, easy-to-learn interface so doctors and assistants can master it quickly. Useful AI-assisted functions include soft-tissue interference management, artifact recognition, automatic removal of excess tissue data outside the arch, automatic tooth segmentation, orthodontic simulation for immediate visual treatment preview, and AI-generated basic diagnostic reports. More features are not always better-choose software that matches actual clinic needs.
Open vs. Closed Architecture ① An open system gives you freedom, flexibility, and long-term control. Scan data can be exported in universal formats (STL, PLY, OBJ) and sent to any third-party laboratory or connected to multiple design software platforms. ② A closed system restricts data processing to the brand's own software or designated partner labs, potentially creating lock-in and higher long-term costs.
04 Ergonomics and Operation
A lightweight, compact intraoral scanner with good ergonomic design feels comfortable in the hand and is easy to operate. It minimizes operator fatigue, discomfort, and occupational injury risk while improving patient comfort. For example, the iTero Element 5D has poor ergonomics; its large size makes operation less convenient.
05 Investment and Long-term Costs
Initial Investment Purchase price ranges from entry-level to high-end. Match the investment to clinic development stage. Basic scanners (domestic or entry-level brands) are more affordable and suitable for small clinics or simple impression needs. Mid-to-high-end scanners with stronger functions suit clinics focused on orthodontics, implants, and complex cases, offering higher accuracy and better data compatibility.
Long-term Costs Most scanners treat the scanning tips as consumables that must be replaced after a set number of sterilization cycles. Some brands charge software update fees or annual service fees; failure to renew can affect usability or data compatibility.
Choosing an intraoral scanner is essentially choosing the future digital operating model of your clinic. The wisest decision is not chasing the absolute best single parameter or feature, but finding the scanner that best matches your clinic's vision in clinical reliability, workflow fit, financial sustainability, and freedom of use.
