Unite Crown Under Partial Workflow

This guide outlines the step-by-step process to submit Crown Under Partial cases to Dandy using Unite software. From initial case creation to final submission, we've got you covered. Follow these instructions to ensure a smooth submission process.

Step 1 - Setup Patient and Lab Details

  • Initiate Case Setup: Create a new patient profile or add a case under an existing patient.
  • Select Dandy Labs: Choose 'Dandy Labs' under 'Scan & Send' to ensure your case is correctly routed to Dandy. If 'Dandy Labs' isn't an option, please contact our Support Team.

Step 2 - Determine Scanning Workflow

If the tooth receiving the crown currently supports or fits with an existing partial denture, we highly recommend completing a pre-pre scan in scan only mode. This scan can be exported and attached to the lab slip before submitting the order to Dandy and will help show pre-prep anatomy so we can ensure the crown fits the existing appliance. 

  • If selected, click the 'Scan Only' box and proceed to Step 3. 

If no existing appliance exists and you are fabricating a partial at the same time as the crown, you do not need to complete the scan only, pre-prep scan. 

  • If this applies or you decide to skip the scan only pre-prep scan, proceed to Step 4.

Step 3 - Complete Scan Only Pre-Prep Scan

Conduct this in a 'Scan Only' setup, scanning only the arch with the original crown or temporary without the partial in place.

Step 4 - Select Clinical Case Details

  • Case Type: Select "Single Units" and "Crown on Preparation." Choose the tooth that requires treatment.

  • Material Selection: Navigate to "Material: Crown" and pick your preferred material from the dropdown menu.

  • Shade Selection: Use "Shade" to select the desired shade, guided by your Vita classic shade guide.

  • Add Pre-Prep Scan: If the patient has an existing partial, you must do a pre-prep scan to capture the prepared tooth without the partial in. You will also complete a prep scan to capture the prepared tooth with the partial in place. 
    • To add the pre-pre scan, navigate to the right side of the case set-up page, and add an additional pre-prep scan by clicking the "additional scan" box.

  • Saving and Setting a Delivery Date: Click "Save" and input a delivery date.
    • Note: While required in Unite, the 'Delivery Date' you select doesn't determine the actual delivery date of your restoration. Upon completing the case's lab slip, you'll see an estimated delivery time.

Step 5 - Prep Tooth and Complete Intraoral Scans

Below, we will outline the scanning process for patients with an existing partial and those without one who will be getting a partial fabricated with the crown. Before moving on to tooth preparation and scanning, please review our Crown and Bridge best practices articles on Recommended Crown and Bridge Margins, Recommended Crown and Bridge Retraction Techniques, and Crown and Bridge Scanning Best Practices. If fabricating the partial with the crown, ensure your scans include all tissue borders needed in the same scans and review our article on Partial Denture Scanning Best Practices

  • Pre-prep scan: If selected because the patient has an existing partial, the pre-prep scan step should capture the prepped tooth without the partial in place.
    • Reminder: You do not need to complete this scan if the patient does not have an existing partial. 

  • Prep scan: If the patient has an existing partial, the prep scan should document the prepped tooth with the partial seated to ensure optimal restoration contact. For patients without an existing partial or those that will get one fabricated with the crown, complete scan without partial.
    • Follow the path of occlusal surfaces to linguals and conclude with buccal. Remember to divide your buccal scans at the midline for precision.
    • For ideal contact between the crown and the existing partial, try to gather data on the partial in direct contact with the restoration.

  • Opposing Arch Scan: Include any existing partial or complete denture on the opposing arch. The scanning sequence remains the same: occlusals, linguals, and buccals.
  • Bite Scans: Conduct left and right bite scans using an existing appliance, if available, to stabilize the VDO and to ensure the patient is in their natural occlusion.
    • Be sure to capture the prepared tooth in one of the bite scans.
    • Listen for the chime indicating a successful scan.

Step 6 - Submit Your Case

  • Analysis and Post-Processing: Utilize the analysis page to review your scans. Select "Post process" and "Send" for case submission.

  • Complete the Dandy Lab Slip: Fill out the Dandy Lab slip with all required information. Include additional instructions or attachments as needed. If you completed a scan only, pre-pre scan, you will export the scan file and attach it to the lab slip before placing your order.
    • Note: Completing the Dandy lab slip entirely is essential for the case to move forward into planning and fabrication. 

  • Placing Your Order: Please continue to select the green buttons at the bottom of the screen to confirm all details and select 'Place Order.'  
    • Note: If you return to the Unite screen before clicking 'Place Order' your order will not be submitted to Dandy and will have a status of 'Pending' in your Dandy Portal.
