Dentistry has come a long way in delivering more comfortable, efficient, and customized prosthetic solutions. If you’re seeking a full guide to dentures, from traditional methods to cutting-edge innovations, you’re in the right place.
One of the most transformative developments in recent years is the introduction of 3D printing in denture fabrication. Traditional dentures often require multiple appointments and detailed manual work, which can lead to longer wait times and less predictable results.
While 3D-printed dentures usually involve a similar number of visits—like impressions, try-ins, or bite registration—the experience is much more comfortable for patients. Instead of biting into bulky moulds, intraoral scanners quickly capture a precise 3D image—no mess, no gagging, just a faster and easier process. The result is a better fit with less hassle.
Are you a dental professional exploring the latest tools? Or perhaps a patient considering modern options? Either case, this guide breaks down how 3D-printed dentures are made, how they compare to conventional methods, their key advantages, and where the technology is headed.
What is 3D printing and additive manufacturing?
3D printing, also known as additive manufacturing, is a technology that creates three-dimensional objects by layering material based on a digital design. Unlike conventional methods that carve or mold materials, this approach builds restorations from the ground up—offering greater precision, customization, and efficiency.
In dentistry, where accuracy and fit are essential, this innovation is transforming how prosthetics like dentures are produced.
How 3D Printing is Used in Dental Prosthetics
The digital workflow has replaced many of the manual steps traditionally involved in denture fabrication. Here’s an overview of how it works:
- Digital Scanning & Design: Intraoral scanners capture a precise 3D image of the patient’s oral anatomy, eliminating the need for physical impressions.
- Computer-Aided Design (CAD): The scan is used to create a custom-fit denture design using specialized CAD software.
- 3D Printing: The digital file is sent to a printer that fabricates the denture base and teeth using biocompatible dental materials, layer by layer.
- Post-Processing: Once printed, the dentures are cleaned, cured, and polished—ensuring durability, aesthetics, and comfort.
This fully digital approach streamlines denture fabrication—reducing production time in the lab while delivering highly accurate, consistent results. For patients, it means improved comfort during impressions and faster turnaround between appointments.
Key 3D Printing Technologies in Dentistry
Advancements in dental prosthetics owe much to several powerful 3D printing technologies. Each brings unique strengths to the table—helping dentists and labs deliver better results with greater speed, precision, and patient comfort.
CAD/CAM
CAD/CAM (Computer-Aided Design and Manufacturing) is foundational to digital dentistry. It allows clinicians and technicians to design and fabricate dentures, crowns, and bridges with exacting accuracy. When integrated with 3D printing, CAD/CAM eliminates manual guesswork, improving fit and function while reducing production time and human error.

SLA (Stereolithography)
SLA uses a focused laser to cure liquid resin into hardened layers. Known for its ultra-high precision and smooth surface finish, SLA excels in creating detailed, custom dental parts like denture bases and individual teeth. It’s ideal for labs that demand tight tolerances and aesthetic refinement.
DLP (Digital Light Processing)
DLP offers similar accuracy to SLA but operates faster. It uses a digital projector to cure entire resin layers at once, making it well-suited for high-throughput environments like dental labs. DLP is particularly useful for printing multiple dentures or components quickly—without compromising detail.
FDM (Fused Deposition Modeling)
FDM is a more accessible and cost-effective printing method that extrudes thermoplastic filament layer by layer. While not typically used for final prosthetics, FDM is highly effective for producing:
- Diagnostic models
- Surgical guides
- Orthodontic devices
Its ability to rapidly prototype and iterate makes it valuable in treatment planning and implant procedures.
SLS (Selective Laser Sintering)
SLS employs a laser to fuse powdered materials—often nylon or composite blends—into highly durable 3D parts. In dental labs, it’s commonly used for:
- Metal frameworks
- Denture bases
- Complex restorations
While SLS delivers strong, detailed results, drawbacks include the complexity of powder handling, slower speeds, and the need for proper ventilation due to airborne particles.
How are 3D-printed dentures made?
3D-printed dentures are fabricated through a streamlined digital workflow that replaces many of the manual, lab-intensive steps used in traditional denture-making.
Although patients still follow a familiar clinical journey—starting with impressions and moving through design, fitting, and insertion—the use of digital scanners and CAD technology transforms how dentures are created behind the scenes.
These tools increase accuracy, reduce remakes, and allow for quicker turnaround between appointments, all while enhancing the patient’s overall experience.
Step 1 – Capturing Impressions
Using an intraoral scanner, the clinician captures a detailed 3D image of the patient’s mouth. Alternatively, a physical impression can be taken and digitally scanned by the lab. This digital model ensures a highly accurate fit from the start.
Step 2 – Digital Denture Design
The scan data is imported into CAD software, where technicians design both the upper and lower arches virtually. This step replaces wax modeling and allows for precise adjustments to shape, bite, and aesthetics before printing.
Step 3 – Preparing for Manufacturing
Once the design is finalized, the software slices the digital model into thin layers. Key manufacturing parameters—such as layer thickness and orientation—are optimized to ensure strength, detail, and printing efficiency.
Step 4 – Printing the Baseplates
Using a dental-grade 3D printer, the denture baseplates are printed layer-by-layer from biocompatible PMMA resin. UV light cures the resin during printing. This stage typically takes 1–2 hours per set.
Step 5 – Cleaning the Baseplates
After printing, the baseplates are rinsed in isopropyl alcohol and cleaned ultrasonically to remove any residual resin. Proper cleaning is essential for post-processing and long-term durability.
Step 6 – Finishing the Baseplates
Support structures are carefully removed, and the baseplates are smoothed using polishing tools like Scotch-Brite wheels. They’re then set aside for tooth assembly.
Step 7 – Printing the Denture Teeth
The teeth are printed separately from tooth-coloured resin using the same UV-curing process. Technicians optimize their layout to minimize support marks, printing all upper and lower teeth as one unit.
Step 8 – Cleaning the Teeth
Just like the baseplates, the teeth undergo alcohol rinsing and ultrasonic cleaning. Supports are trimmed off and the surfaces smoothed before assembly.
Step 9 – Denture Assembly
A small amount of resin is applied to each tooth socket in the baseplate. The printed teeth are seated and secured in place with additional resin, then cured under UV light for initial bonding.
Step 10 – Final Curing
To ensure full polymerization, the assembled dentures are submerged in a heated glycerin bath (60°C) and UV-cured for 10 minutes per side. This boosts strength and colour stability.
Step 11 – Polishing and Quality Check
Technicians inspect and polish the final dentures, ensuring a smooth, lifelike finish. The prosthetic is now ready for delivery, often within days instead of weeks.
