Public hospitals and large dental organizations typically procure intraoral scanners through formal tender processes. Parameter settings must meet clinical requirements while remaining open, fair, and free from exclusive or preferential clauses.
Core Principles for Parameter Setting
Base requirements on actual clinical needs - do not simply copy any single brand's marketing specifications.
Use terminology from national and industry standards.
Distinguish between mandatory parameters (must-meet) and optional/scoring parameters (bonus points).
Avoid vague language such as "approximately" or "around," and also avoid ultra-precise values that only one brand can meet.
Explicitly allow positive deviation (performance better than the stated requirement is acceptable).
Recommended Mandatory Parameters
| Parameter | Suggested Requirement | Notes |
|---|---|---|
| Medical Device Registration | Valid NMPA Class II Medical Device Registration Certificate | Legal market-entry baseline |
| Imaging Technology | Structured light / confocal / active wavefront sampling, etc. (no specific technology mandated) | Avoids technology lock-in |
| Single-Crown Accuracy | ≤15 μm (third-party test report required) | Based on ISO 12836 |
| Full-Arch Accuracy | ≤60 μm (third-party test report required) | Clinically relevant performance |
| Full-Arch Scanning Time | ≤3 minutes | Efficiency requirement |
| Scanning Tips | Autoclavable, ≥50 sterilization cycles | Infection-control standard |
| Data Format | Open export of STL / PLY / OBJ | Prevents closed-system lock-in |
| Color Scanning | True-color 3D scanning supported | Standard clinical expectation |
| Software | Chinese interface; lifetime free use or clearly stated annual fee | Avoids hidden costs |
| Warranty | Whole unit ≥2 years; tips ≥6 months | After-sales protection |
| Training | On-site installation training + ≥2 advanced training sessions | Ensures successful clinical adoption |
Common Exclusive Clause Traps (Must Be Avoided)
Mandating a specific imaging technology (e.g., "must use confocal technology").
Specifying the exact number of scan-body libraries unique to one brand.
Setting weight or dimensions that only one brand's product can meet.
Requiring "seamless integration" with a specific brand's CBCT or CAD software.
Including parameters that can only be satisfied by a single company's patented technology.
Recommended Bonus / Scoring Items
AI-assisted scanning functions
Wireless connectivity
Built-in caries detection capability
Cloud data platform
Number of local after-sales service centers
Existing installed base of similar devices
Tender specifications should be jointly developed by clinicians, the medical equipment department, and the procurement team, then reviewed by legal counsel for compliance.
