This article reviews the scan viewer tools. The scan viewer enables DSOs, doctors, and labs to review, validate, and troubleshoot intraoral scans before moving forward with design and fabrication. Each tool plays a role in reducing remakes, ensuring accuracy, and improving collaboration.
-
Doctors/Assistants: Can validate scan quality, margin visibility, and occlusion before submission.
-
DSOs: Ensures consistency across providers and reduces remakes by catching errors earlier.
-
Lab Technicians: Confirms feasibility of designs, especially for implant angulations and complex multi-unit cases.
View & Layer Controls
What it does:
-
Lists all available scans from the case (e.g., Bite Bite, Bite 2, Upper Jaw, Lower Jaw).
-
Each scan can be toggled on/off, viewed in color, or switched to mesh mode.
Purpose:
-
Allows users to isolate different anatomical areas for inspection.
-
Makes it easier to verify scan completeness and alignment between arches.
Why it matters:
-
Ensures margins, occlusion, and anatomy are captured before fabrication.
-
Reduces the chance of missed prep areas or distorted opposing scans.
-
Order Scans List (Bite, Upper Jaw, Lower Jaw, etc.)
-
Visibility Toggle (👁️ icon): Show/hide a specific scan layer (e.g., upper jaw, lower jaw).
-
Color Toggle (rainbow icon): Switch between color texture (natural tooth shades, gingiva) vs monochrome/mesh view for clarity.
-
Useful for isolating anatomy or reviewing opposing arches independently.
-
Camera & Navigation Controls
-
Restore Camera View
-
Resets the model to the standard orientation (default occlusal/frontal view).
-
Purpose: Quick reset after rotating/zooming.
-
Why it matters: Prevents disorientation, saves time during review.
-
-
Zoom Visible
-
Centers and zooms on the selected anatomy (e.g., only the upper jaw).
-
Purpose: Focused inspection of a single scan region.
-
Why it matters: Efficient review without unnecessary model manipulation.
-
-
Snap to POI (Path of Insertion)
-
Automatically orients the model to the optimal insertion path for a crown, bridge, or appliance.
-
Purpose: Highlights potential undercuts or divergent angles that could block seating.
-
Why it matters: Prevents costly remakes due to improper insertion paths. Critical for multi-unit restorations.
-
Cross-Section & Clipping Tools
-
Enable Clipping Plane (C icon)
-
Slices through the 3D model to reveal internal anatomy or prep depths.
-
Purpose: Verify reduction depth, margin visibility, and internal clearance.
-
Why it matters: Ensures that enough tooth has been reduced for material thickness (e.g., zirconia crown).
-
-
Enable Reverse Plane (R icon)
-
Flips the clipping plane orientation (e.g., buccal → lingual).
-
Purpose: Provides alternate perspectives when analyzing margins.
-
Why it matters: More thorough QC of preps and undercuts.
-
-
Hide/Show Cross Section
-
Toggles all clipping planes on/off.
-
Purpose: Quickly return to a full model view.
-
Why it matters: Simplifies workflow after detailed slice inspections.
-
Utility Tools
-
POI (Path of Insertion Button)
-
Runs a calculation to detect the optimal insertion axis for prosthetics.
-
Purpose: Identifies undercuts and flags if prep angles will cause seating issues.
-
Why it matters: Ensures restorations are feasible before lab work begins. Reduces adjustments chairside.
-
-
Restore Defaults
-
Clears clipping planes, resets POI view, and restores default camera orientation.
-
Purpose: Clean slate for re-review.
-
Why it matters: Avoids confusion if multiple tools are applied at once.
