Mainstream overseas intraoral scanner brands have built differentiated functional focuses and ecosystem barriers based on their core technologies, meeting the needs of different types of clinics. These differences go far beyond hardware parameter competition - they represent distinct definitions of the future of digital workflows.
1. 3Shape TRIOS
In the timeline of rapid digital dentistry development, 3Shape has long been a leading representative. The 3Shape TRIOS series is widely recognized as a high-end industry benchmark. Its core value extends far beyond "fast 3D model acquisition" - it builds a complete digital workflow founded on precise data, powered by robust software, and connected through an open ecosystem.
01 Clinical Accuracy & Detail Capture Recognized as one of the industry "gold standards," especially excellent at capturing fine structures such as preparation margins and surface texture, laying a solid foundation for high-quality restorations (crowns, veneers, etc.).
02 Powerful Software Ecosystem & Integration The accompanying 3Shape Dental System / Unite software is extremely powerful. It is not just a scanning tool but a complete design platform supporting restorative, orthodontic, and implant planning. Deep collaborations with numerous global laboratories, implant systems, and material brands enable seamless workflows.
Best suited for: High-end general practices, restorative specialists, and large laboratories pursuing ultimate accuracy and efficiency.
2. iTero
iTero scanners are primarily positioned as tools for the Invisalign workflow rather than a fully comprehensive digital dentistry solution. Earlier models, while functional in orthodontics, faced strong competition in restorative workflows, performance, ergonomics, and versatility.
Deep Orthodontic Adaptation Deep integration with the Invisalign system is its greatest advantage. Scan data can be used directly for Invisalign treatment design, with unique clinical simulation tools that dynamically visualize tooth movement, significantly improving patient communication and case acceptance.
NIRI Near-Infrared Imaging Technology One device, dual purpose. Detects interproximal caries without X-rays, showing 66% higher sensitivity than bitewing radiographs for supragingival interproximal caries. Near-infrared light penetrates enamel to display internal structural changes in real time with zero radiation. Doctors can intuitively observe early caries signs.
Best suited for: Orthodontic clinics (especially Invisalign users) and general practices that emphasize preventive diagnostics and digital patient communication.
3. Sirona Primescan (Dentsply Sirona)
Dentsply Sirona's intraoral scanners, particularly the flagship Primescan series (including the newer Primescan 2), center their core functions around one ultimate goal: achieving precise, efficient, and predictable chairside full-digital restorative closed-loop experiences.
CEREC Ecosystem Core Perfect integration with the CEREC chairside restorative system enables a one-stop "scan–design–mill" chairside solution with a long history and mature processes.
Cloud-Native Scanning Primescan 2 eliminates the need for expensive high-performance laptops or desktops that were traditionally required in digital dentistry. Clinics can now scan on almost any device - from basic laptops to tablets.
Best suited for: Clinics focused on or already invested in CEREC chairside restorations - the classic choice for same-day restorative dentistry.
4. Medit
Medit intraoral scanners compete on high cost-performance, ease of use, and technological innovation. Market share has steadily increased worldwide, especially popular among small-to-medium clinics and emerging digital dental practices.
01 Metal Scanning & Processing Technology Intelligent metal recognition system automatically identifies and optimizes parameters for metal surfaces, significantly reducing reflection interference from metal crowns and fillings. This is one of Medit's core patented technologies. Metal scanning accuracy exceeds industry average levels, particularly suitable for posterior metal restorations and reducing remake rates.
02 Special Implant & Restorative Functions Emergence profile locking function allows users to lock the scanned soft-tissue contour so it is not overwritten by rebound tissue data after healing abutment removal during rescanning - a key innovation for precise implant abutment and crown restorations. Mandibular movement trajectory recording captures complex lateral and protrusive movements for dynamic occlusion analysis and restoration design. SmartX edentulous solutions feature simplified scanning workflows with automatic matching that reduces registration errors in full-arch implant cases, saving time for doctors, technicians, and patients.
Best suited for: Clinics newly adopting digital technology, those prioritizing cost-performance, and small-to-medium practices focused on restorative and implant work.
5. Planmeca
Planmeca intraoral scanners (such as Emerald / Emerald S) have become mainstream choices in global digital dentistry, particularly strong in European and Asia-Pacific markets, thanks to excellent technical performance, convenient operation, and a complete digital ecosystem.
Intelligent Anti-Fog System Patented heated mirror technology with built-in heating elements keeps the mirror temperature slightly higher than the oral environment, completely solving fogging issues and supporting continuous scanning without interruption. Plug-and-play readiness within seconds after power-on, with no preheating wait, greatly improves clinical efficiency.
Integrated FIT™ Chairside Solution Full chairside restorative workflow integration: Planmeca FIT™ system seamlessly combines intraoral scanning (PlanScan / Emerald), restoration design (PlanCAD), and chairside milling (PlanMill) within the same software interface, enabling same-day restorations and higher efficiency.
Best suited for: High-end clinics pursuing precise restorations, implant treatment, and rapid chairside solutions.
Each brand's core advantages make direct substitution difficult. When selecting a scanner, clinics are essentially choosing a long-term workflow model, partnership ecosystem, and cost structure. Understanding the distinct strengths of different systems and matching them to the clinic's actual needs leads to wiser decisions than simply comparing technical parameters.
