The following contains an overview and instructions for using the Undercut Tool. This tool allows Chairside to identify undercuts in your crown prep after you define a path-of-insertion for your future crown.

Instructions for Use

Step 1 - Navigate to the Review Scan menu after completing all required scans

Step 2 - Select the Undercut button

Located on the bottom of the Review Scan page.

Step 3 - Rotate the scan to an occlusal view of the crown prep

The scan should be oriented as close to the anticipated path-of-insertion for the future crown.

Step 4 - Once in its proper orientation, select the Set Direction button

Tip: Ensure the occlusal surface and margins of the prep are fully visible, then click 'Set Direction.' Shaded areas indicate undercut; check for enough surface area above these for proper proximal contacts.

Step 5 - Rotate the scan to evaluate undercuts present on your prep

The long arrow represents the path-of-insertion you set.

Undercuts will be displayed as blue patches based on the path-of-insertion that you set in steps 3 and 4.

To Exit the tool, click the Undercut button again.
