Digital Relines For Dentures

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

1. Remove the denture from the patient's mouth.
2. Perform a 360° extraoral scan of the denture without any impression material in place.
3. Capture a bite scan with the denture in the mouth to establish the current relationship.

Step 3: Perform Extraoral Scan With Wash

1. Apply a light body wash to the intaglio surface of the denture.
2. Seat the denture in the patient's mouth to capture the updated tissue anatomy.
3. Perform a second 360° extraoral scan with the impression material still in place.
4. 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

• A new precision-fit, relined Signature denture
• 5-day turnaround from scan to delivery

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 molding is not required for digital relines.
• Scanning Accuracy: Ensure the scanner captures the full borders of the peripheral anatomy.
• Material Integrity: Do not remove the wash material before scanning, as this preserves the anatomical accuracy required for the new intaglio design.

Who is this solution for?

• Doctors with existing Dandy dentures (Final or Reline)
• Doctors with non-Dandy dentures that require relining
• Doctors using Chairside software who want a fast, digital workflow

Eligibility by Denture Type

Reline Types 

• A fully digital reline.
  1. The existing denture is rescanned and redesigned for a better fit. This process provides a more accurate and longer-lasting result than traditional chairside or lab relines. Soft relines are not supported today — all relines are fabricated as a new hard reline through our digital workflow.
• Updated intaglio anatomy is merged into the original denture design.

Digital Reline Eligibility 

• If the last denture for the patient's x arch was a Final Denture (submitted from a Bite Rim or Copy/Reference flow)
  1. No limit. You can Reline this denture >0 days from the product being delivered.
  2. However, if this Denture was relined, you can only reline the Reline
• If the last denture for the patient's x arch was a Final Denture (submitted from an Immediate Denture flow)
  1. You can Relined this denture >0 days and <=18 months from the product being delivered
  2. If this Denture was relined, you can only reline the Reline
• If the last denture for the patient's x arch was a Reline…
  1. No limit. You can Reline this relined denture >0 days from the product being delivered

Reline vs. New denture

• A Reline, although a new denture, updates only the intaglio surface. No other design changes are included.
• A New Denture is required if a different material is requested or if design changes are needed.

Denture Rebases

• Dandy does not offer relines for rebases
• If a rebase is needed, a full new denture will need to be ordered
