Overview: This article provides comprehensive, step-by-step instructions for managing various dental restoration workflows using 3Shape Unite software. Users will learn how to set up patient profiles, capture intraoral scans, and submit orders directly to Dandy Labs.
Conduct Diagnostic Scans
Diagnostic scans help dental practices streamline patient education and treatment planning.

Set Up Patient Profiles
Search for existing patients: Use the 'Search for a Patient' tab on the top left to find an existing profile.
Create new patient profiles: Select 'New Patients' on the left side of the screen.
-
Enter patient details: Input the patient's first name, last name, and date of birth, then select 'Add'.
Perform the Diagnostic Scan
Navigate to Dandy Labs: Select 'Dandy Labs' under the 'Scan and Send' menu.
Select Scan Only: Check the 'Scan Only' box to proceed without sending a formal order to Dandy.
Capture the Lower Arch: Start at a posterior tooth and follow an occlusal-lingual-buccal path.
Capture the Upper Arch: Flip the scanner mirror tip 180 degrees and follow the same occlusal-lingual-buccal path.
Record Occlusion: Perform left and right bite scans while the patient is in natural centric occlusion.
Manage Fixed Restoration Workflows
These steps apply to Crown, Bridge, and Veneer cases.

Configure Case Details
Select Restoration Type: Choose between "Single Units" (Crown/Veneer) or "Bridge".
Choose Material and Shade: Select the desired restorative material and Vita classic shade from the dropdown menus.
Set Delivery Date: Input a delivery date to fulfil software requirements (Note: Actual delivery is determined by the Dandy lab slip).
Scanning and Preparation
Perform Pre-Prep Scan: If required for aesthetic matching, capture the arch before tooth preparation.
Prepare the Tooth: Follow Dandy's best practices for margin preparation and retraction.
Scan the Prepped Tooth: Start scanning on an adjacent tooth to help the software identify the prep area.
Capture Clear Margins: Ensure complete interproximal data and visible margins are captured in the final scan.
Manage Crown Under Existing Partial
Configure Patient and Case Details
To begin a Crown Under Partial case, create a new patient profile or select an existing patient in the Unite software. Under the Scan & Send menu, select Dandy Labs. If Dandy Labs does not appear as an option, contact the Support Team for assistance.
Select the Scanning Workflow
Users must determine the scanning path based on whether the patient has an existing appliance:
Existing Partial Denture: Use a "Pre-Prep" scan in Scan Only mode to capture the pre-preparation anatomy. This ensures the new crown fits the existing appliance.
New Partial Denture: If Dandy is fabricating the partial and crown simultaneously, skip the Scan Only pre-prep step.
Case Specifications
Select the following details on the case setup page to ensure proper routing:
Case Type: Select Single Units and Crown on Preparation, then choose the specific tooth.
Material: Choose the preferred restorative material from the dropdown menu.
Shade: Select the desired shade using the Vita Classic guide.
Additional Scans: If the patient has an existing partial, click the Additional Scan box to add a pre-prep scan.
Delivery Date: Select a date to save the case. Note that the final delivery estimate is confirmed on the Dandy lab slip, not within Unite.
Complete Intraoral Scans
Follow these specific scanning protocols to ensure restoration accuracy:
Pre-Prep Scan (Existing Partial Only)
If the patient has an existing partial, perform the pre-prep scan on the arch with the original crown or temporary. Do not have the partial denture in place for this specific scan.
Prep Scan
With Existing Partial: Capture the prepared tooth with the partial denture fully seated. This documents the contact point between the partial and the new restoration.
Without Existing Partial: Capture the prepared tooth normally without any appliance.
Technique: Scan the occlusal surfaces first, followed by lingual and buccal. Divide buccal scans at the midline for higher precision.
Opposing Arch and Bite Scans
Opposing Arch: Scan the full opposing arch, including any existing dentures or partials.
Bite Scans: Complete left and right bite scans. If the patient has an appliance, use it during the bite scan to stabilise the Vertical Dimension of Occlusion (VDO). Ensure the prepared tooth is visible in at least one bite scan.
