3D-printed versus milled complete dentures in adults who are fully denture dependent
Official title: An Open, Single-center, Prospective, Randomized, Two-armed, Interventional, Post-market Clinical Investigation of 3D Printed Complete Dentures and Milled Complete Dentures During a 5-year Follow-up Period
Run by Dentsply Sirona Implants and Consumables · NCT07586774 · Data updated 2026-11-12
This study tests whether 3D-printed dentures stay in place and perform as well as milled dentures over five years in adults who need full upper and/or lower dentures.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older who need complete dentures for both the upper and/or lower jaw and can commit to five years of follow-up.
✕Probably not a fit
Patients who do not respond to the materials or fabrication methods, or who have conditions limiting denture use or follow-up may not benefit.

What this trial studies
This is a two-arm, single-center study comparing 3D-printed complete dentures to milled complete dentures in adults with complete edentulism. Participants will wear either 3D-printed Lucitone Digital Print or milled Lucitone Digital Fit dentures and be followed for five years to assess denture survival, function, and safety. The primary goal is to determine the one-year survival rate of each denture type in the upper and lower jaws. Outcomes will include denture retention, comfort, and any adverse events related to the materials or fabrication method. The study is conducted at a single site with a requirement for long-term follow-up visits.
Why it matters
Potential benefit: If successful, patients could have access to durable, well-fitting dentures with potentially improved durability or fit from digital fabrication.
How similar studies have gone: Prior digital denture approaches have shown promising results, but long-term comparative data between 3D-printed and milled dentures are limited.
