Overview: Learn how to perform a digital reline workflow to improve denture fit using 360° extraoral scanning without sending the original appliance to the lab.
Denture Reline Overview
A Digital Reline is a chairside workflow that refreshes the fit of an existing denture. Patients keep their current denture throughout the process while Dandy manufactures a new Signature Denture digitally designed to match the patient's current anatomy.
Clinical Indications
Use this workflow for patients experiencing:
- Tissue changes post-delivery.
- Minor discomfort or looseness.
- Re-adaptation requirements after healing.
Step-by-Step Scanning Instructions
Step 1: Scan the Opposing Arch
Perform a standard scan of the opposing dentition to ensure proper occlusion mapping.
Step 2: Perform Extraoral Scan Without Wash
- Remove the denture from the patient's mouth.
- Perform a 360° extraoral scan of the denture without any impression material in place.
- Capture a bite scan with the denture in the mouth to establish the current relationship.
Step 3: Perform Extraoral Scan With Wash
- Apply a light body wash to the intaglio surface of the denture.
- Seat the denture in the patient's mouth to capture the updated tissue anatomy.
- Perform a second 360° extraoral scan with the impression material still in place.
- Submit the case through the Dandy portal.
Step 4: Delivery and Final Fit
Dandy will deliver the new Signature Denture to your office within 5 business days. The patient receives a precision-fit appliance without experiencing downtime away from their original denture.
What You’ll Receive

Materials Used
- Lucitone Digital Print Resin (Dentsply Sirona), Acrylic, or Milled
Best Practices for Successful Relines
- Impression Technique: Use only a light wash; full border moulding is not required for digital relines.
- Scanning Accuracy: Ensure the scanner captures the full borders of the peripheral anatomy.
- Material Integrity: Do
