A well-planned scanning path significantly improves both efficiency and data quality. This practical guide provides recommended scanning sequences for common clinical situations, helping clinicians capture complete, accurate digital impressions with fewer voids and rescans.
Full-Arch Scanning (Orthodontics / Full-Mouth Restorations)
Occlusal surfaces: Start at the distal of one second molar and move steadily along the central fossae to the contralateral second molar.
Buccal surfaces: Return to the starting point, angle the tip approximately 45°, and scan the buccal surfaces from posterior to anterior and back.
Lingual / palatal surfaces: Follow the same approach on the lingual or palatal side.
Bite registration: Capture buccal intercuspation on both left and right sides.
Memory aid: "Occlusal first → buccal & lingual → bite last."
Single Posterior Crown Scanning
First scan the occlusal surfaces of 1–2 adjacent teeth on each side of the preparation (to establish solid reference landmarks).
Capture the occlusal surface of the prepared tooth.
Angle 45° buccally to scan the buccal surface and finish line.
Angle 45° lingually to scan the lingual surface and finish line.
Capture the proximal areas from both buccal and lingual approaches.
Scan the opposing occlusal surfaces and buccal cusps.
Record the bite relationship.
Anterior Aesthetic Restoration Scanning (Veneers / Crowns)
First capture the full labial surfaces of the anterior segment (important aesthetic reference).
Scan the preparation's incisal edge and labial cervical margin.
Capture the palatal / lingual margins.
Record the proximal contact areas thoroughly.
Scan the opposing incisal edges and occlusion.
Capture the bite relationship (including overjet and overbite).
True-color scanning is recommended to assist shade communication with the laboratory.
Implant Scanning Sequence
Complete opposing arch.
Working arch natural teeth and mucosa (with healing abutments still in place).
Bite registration with healing abutments.
Seat scan bodies and perform 360° scan of each.
Remove scan bodies and immediately capture the soft-tissue emergence profiles.
Multi-Unit Bridge Scanning
First scan a complete half-arch to establish a stable reference framework.
Capture detailed data of each abutment preparation.
Record the edentulous ridge and soft-tissue morphology.
Scan the opposing arch and bite relationship.
Universal Scanning Principles
Establish a broad reference framework before focusing on fine detail.
Progress from areas rich in anatomical features toward feature-poor regions.
Rotate and inspect the live 3D model after each segment.
Always capture the bite relationship last.
How the Right Scanner Supports Efficient Path Execution
Following an optimal path is easier with a scanner that offers real-time feedback, deep depth of field, and smooth tracking. The Aident AI-30 Intraoral Scanner helps clinicians execute these sequences efficiently with:
Fast scanning speed (30 fps) for quicker full-arch and multi-unit acquisition
20–25 mm ultra-deep depth of field that reduces voids when changing angles
≤10 μm accuracy for precise margin and preparation capture
Powder-free true-color imaging (especially useful for anterior aesthetic cases)
Lightweight design (156–198 g) that improves control during multi-angle scanning
Fully open STL/PLY/OBJ output compatible with all major CAD and laboratory systems
These features support cleaner data and higher first-time success rates across restorative, implant, and orthodontic workflows.
