How to have your scans & prep analysed by AI Scan Review
Step 1: Start a single-unit crown case
- Set up a single-unit anterior or posterior crown case in Chairside.
- Note: AI Scan Review will only run for single-unit crown cases. Support for additional workflows is coming soon.
- Click here for a step-by-step walkthrough of the crown workflow.
Step 2: Complete all required scans
- Capture needed scans by following prompts in Chairside, including:
- Lower arch scan
- Upper arch scan
- Bite scan
- Prep scan
Step 3: Proceed to 'Review' menu
- Once all scans are captured, navigate to the Review menu.
- AI Scan Review will begin automatically (shown below). No clicks needed to initiate.
- Note: analysis takes ~30 seconds. This may vary based on internet speed.
- What AI Scan Review checks on your prep:
- Occlusal clearance
- Undercuts
- Margin line visibility (to generate a proposed margin line)
Step 4: View results
- If no issues are detected: a message confirms your prep is lab-ready.
- We recommend double-checking your prep and scans before placing your order even with this confirmation.
- If issues are detected: a notification appears on the right side of your screen with details and next steps.
Fixing an Occlusal Clearance Issue
Step 1: Click into the alert
- Click the clearance alert to see specific feedback and step-by-step guidance on how to fix the issue.
Step 2: Review areas of prep highlighted in purple
- If there’s insufficient clearance (based on your prep, material, and bite scan), affected areas will be shaded in purple.
Step 3: Choose how to proceed
- You can:
- Re-scan after refining the prep in your patient's mouth.

Step 4 (Optional): Selecting 'Proceed as-is'
