Before sending digital impression data to the laboratory, the clinician should perform a thorough quality check. This practical guide outlines the key acceptance standards that technicians care about most, helping you reduce remakes and improve communication with the lab.
Three Core Standards for Qualified Intraoral Scan Data
1. Clear and Complete Finish Lines
The restoration margin must be 100% visible, continuous, and unobstructed.
Equigingival or subgingival margins must be fully exposed after proper gingival retraction.
The margin area must be free of blood, saliva, or residual retraction cord.
The preparation surface should be smooth, without overhangs/flashes or undercuts.
At least 1–2 mm of healthy gingival data surrounding the margin should be present.
2. Complete Data Without Voids
All surfaces of the preparation or implant scan body must be fully captured.
Contours and proximal surfaces of adjacent teeth must be complete.
Opposing arch occlusal and buccal/lingual information must be sufficient.
No extraneous data (fingers, tongue, cotton rolls, etc.) should remain.
No stitching gaps or layering artifacts should be present.
3. Accurate Occlusion / Bite Relationship
The patient must have been scanned in a stable maximum intercuspation position without movement.
Left and right occlusal contact points should be clear and logical.
The recorded bite must match the actual clinical situation.
In cases with multiple missing teeth or free-end saddles, the bite relationship must remain stable.
Additional Requirements by Restoration Type
Implants: Scan bodies fully seated, free of deformation, and soft-tissue emergence profiles complete and natural.
Bridges: Sufficient soft-tissue and ridge morphology data in the edentulous area.
Veneers: Complete incisal and proximal data; true-color information is highly preferred for shade communication.
Complete dentures: Intact border seal areas and reliable jaw relation recording.
Recommended Self-Check Tools
Rotate the 3D model 360° and visually inspect every surface.
Use the software's margin-line tool to confirm and refine the finish line.
Use the occlusion analysis tool to verify contact points.
Use the undercut detection tool to check the path of insertion.
Use the measurement tool to confirm adequate occlusal clearance.
Magnify the margin areas and inspect them segment by segment.
Spending just two minutes on these checks before sending the data can prevent more than 80% of remakes caused by incomplete or inaccurate digital impressions.
How the Right Scanner Supports Lab-Ready Data
High-quality, lab-accepted scans are easier to achieve with a scanner that delivers precision, clear real-time feedback, and open data formats. The Aident AI-30 Intraoral Scanner helps clinicians meet laboratory standards with:
≤10 μm accuracy for sharp finish-line definition
20–25 mm ultra-deep depth of field that reduces voids around critical areas
Powder-free true-color imaging with intelligent anti-fog heating
Lightweight design (156–198 g) for better control during detailed scanning
Fully open STL/PLY/OBJ output that ensures seamless communication with any laboratory or CAD system
These features support cleaner data submission and higher first-fit success rates.
Deliver Lab-Ready Digital Impressions Consistently
A quick but systematic quality check before data transfer is one of the most effective ways to reduce remakes and improve collaboration with the laboratory. Combine disciplined self-inspection with a reliable intraoral scanner for the best results.
