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

• Teeth: Lucitone Digital IPN Premium Tooth Resin
• Manufacturing: Carbon™ 3D printed
• Turnaround Time: 5 business days

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.

FAQs

1. 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
2. Eligibility by Denture Type

3. What type of reline does Dandy offer? 
   • A fully digital reline.
     1. The existing denture/partial 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.
4. How much will Dandy Digital Relines cost?
   • Dandy will price digital relines specific to the arch being relined, maxillary vs mandibular 
   • For Dandy fabricated dentures: $99 per arch plus add-ons.
   • For non-Dandy-fabricated dentures: $149 per arch, plus add-ons.
5. Who is the Digital Reline solution designed for?
   • 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
6. How is a reline different from a 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.
7. Are try-ins available for relines? 
   • No. Try-ins are not currently offered for relines.
8. Does Dandy offer denture rebases?
   • Not at this time.
   • For rebases
     1. Dandy recommends a full denture replacement.
