For most of the last century, dentures were made the same way. A technician took a physical impression, poured a stone model, arranged wax teeth, invested the whole assembly, burned out the wax in a kiln, and pressure-packed acrylic into the void. The lost-wax technique served dentistry for generations, but it was slow, inconsistent, and difficult to reproduce.

The Digital Revolution in Denture Manufacturing
Digital dentures replaced the traditional process with a scanned, designed, milled, and verified workflow. Today, the same clinical outcome that once required 5-7 appointments and weeks in the lab can be achieved in 2-3 visits with superior fit predictability, documented digital records, and materials validated in more than 25 peer-reviewed studies.
Understanding exactly how digital dentures are made gives dental professionals the clinical confidence to discuss the technology with patients and referral partners, and to choose a manufacturing partner that delivers on the promise. This guide covers the complete digital denture manufacturing process as used by AvaDent digital dentures, the company that first commercialized fully digital dentures and holds 80+ patents protecting its proprietary workflow.
Step 1: Capturing the Digital Record
Every digital denture starts with accurate data capture. Unlike traditional impressions, which introduce distortion through material shrinkage and stone expansion, digital records are dimensionally stable from the moment they are taken.
There are two primary pathways for capturing the initial record:
Option A: Intraoral Scanning
For digitally equipped practices, an intraoral scanner captures the edentulous ridge, palate, and surrounding anatomy in a series of overlapping images that software stitches into a precise 3D mesh. The clinician also captures the bite relationship using an interocclusal record, establishes vertical dimension of occlusion (VDO), and scans any existing denture that serves as an aesthetic reference.
AvaDent's digital workflow integrates natively with seven major scanner platforms:
- iTero (Align Technology), AvaDent ID #113495, direct portal connection
- 3Shape Trios, via 3Shape Communicate portal
- Dentsply Sirona PrimeScan, via Connect Case Center / DS Core
- Medit, via Meditlink portal
- Dexis, via Dexis Connect
- Shining 3D, direct STL file transfer
- Desktop scanners, universal STL upload via the AvaDent Dashboard
Practices without an intraoral scanner have two additional paths: scan physical models with a desktop scanner, or ship physical records to AvaDent for in-house digitization. Every workflow produces the same result, a validated set of digital files ready for design.
Option B: Traditional Impression with Digital Conversion
Clinicians who prefer conventional impressions can take standard alginate or PVS impressions, pour stone models, and submit the physical records. AvaDent scans those records at the lab, converting them into STL files that enter the same design pipeline as native digital submissions. This path allows any practice, regardless of technology investment, to access the full digital manufacturing workflow.
How Are Digital Dentures Designed?
Once digital records arrive at the lab, AvaDent's proprietary Computer Aided Engineering (CAE) platform takes over. This is where digital denture manufacturing diverges most significantly from traditional techniques.
Traditional lab design depends heavily on the technician's manual skill. The CAE platform systematizes and automates that design logic while still producing individualized prosthetics tailored to each patient's anatomy.
During this phase, the design team:
- Segments the intraoral scan to identify tissue boundaries, undercuts, and ridge topography
- Positions the denture base to optimize load distribution and retention
- Selects tooth form, shade, and arrangement from a validated digital library
- Applies AvaDent's proprietary Digital Positioning Technology to set the teeth in precise anatomical alignment
- Exports a virtual try-in for clinician review and patient approval before any milling begins
The digital design file is stored permanently in the cloud. If a patient loses or breaks their denture years later, an identical replacement can be milled from the saved file without repeating any clinical steps. That reproducibility is a significant advantage for patients and practices compared with traditional methods where records are often discarded after fabrication.
Design typically completes within 1-2 business days of receiving digital records. A digital preview is sent to the clinician for approval before the case advances to manufacturing.
Step 3: Adaptive Occlusion and AI-Powered Articulation
Before the milling file is finalized, AvaDent runs every case through Adaptive Occlusion software, a proprietary AI system that dynamically optimizes the occlusal scheme based on the patient's specific anatomy and bite registration.
Traditional articulation relies on an articulator set to average anatomical values. Adaptive Occlusion draws on a database of over 70 billion data points to generate a personalized occlusal map that accounts for the patient's unique jaw movement patterns. The result is a denture designed to seat correctly without the series of chairside occlusal adjustments that characterize conventional delivery.
Clinical evidence supports the technology's impact. Every prosthesis manufactured with Adaptive Occlusion undergoes 100% quality verification: a 3D scan of the finished denture is compared against the original digital design file, confirming that the physical product matches the approved virtual model. This closed-loop QC process eliminates the manufacturing variation that makes conventional dentures unpredictable.
The clinical payoff is measurable: Adaptive Occlusion eliminates approximately 98% of the adjustment appointments that follow conventional denture delivery.
What Material Are Digital Dentures Made From?
Approved design files advance to AvaDent's CNC milling department, where the digital denture is machined from a solid puck of eXtreme-Cross-Linked (XCL) PMMA material. Understanding what happens in this step explains why milled digital dentures outperform both conventional heat-cured acrylics and many 3D-printed alternatives.
Why Monolithic Construction Matters
Traditional dentures are assembled from separate components: a processed acrylic base with teeth bonded into it using a secondary adhesive. That bond line is a structural weakness. It is the most common site of tooth pop-offs and fractures, and it creates a porosity-prone interface where bacteria can colonize.
AvaDent's monolithic approach mills the prosthetic from a single, pre-polymerized PMMA block. There are no bonds to fail and no bonded tooth-to-base interfaces. Clinicians comparing material options can review AvaDent's product portfolio and the XCL-1 product details for available formulations.
XCL Material Properties
The XCL material used in milling is not standard acrylic. It is manufactured under high pressure using a proprietary extreme cross-linking process that creates a three-dimensional polymer network with substantially different physical properties:
- Up to 8 times stronger than conventionally fabricated dentures
- Virtually porosity-free, with a high-density, non-porous surface that resists bacterial colonization, including Candida albicans and Streptococcus species, and staining
- Minimum thickness of 1.5 mm versus 2.0 mm for 3D-printed dentures, enabling 25% thinner design while maintaining superior strength
- Ultra-low residual monomer content, because XCL blocks are fully polymerized before milling
- Superior color stability, validated in peer-reviewed research through 2024
The material is available in two primary formulations. XCL-1 (monochromatic) provides a single-layer dentin base in 12 shades for straightforward aesthetic cases. XCL-2 (polychromatic with Natural Morphology) uses a multi-layer construction with a translucent enamel layer for maximum aesthetic depth. Both are milled to tolerances measured in microns, precision that manual laboratory work cannot match consistently.

How Does AvaDent Verify Quality on Every Denture?
After milling is complete, every prosthetic undergoes 100% quality control inspection. This is not sampling or periodic auditing. AvaDent performs a 3D scan of every single unit, then compares the scan data computationally to the original digital design file.
This step catches any deviation introduced during milling, material handling, or setup. If the physical prosthetic does not match the approved digital design within tolerance, the unit is rejected and remilled before it ever ships.
For clinicians, this means that the prosthetic you receive has been verified against the design you approved. The QC step is one of the most significant structural differences between AvaDent's manufacturing process and conventional lab workflows, where quality depends on the subjective assessment of an individual technician. AvaDent's digital denture technology and clinical studies provide additional context for practices evaluating the evidence behind the workflow.
Step 6: Finishing and Delivery
Verified units advance to final finishing, surface polishing, and any custom characterization requested during the design phase before being packaged for shipping. AvaDent ships all cases via free 2-day FedEx delivery from manufacturing facilities in Scottsdale, Arizona for US cases and Tilburg, Netherlands for European cases.
Total turnaround from submission of approved design to delivery runs 6 business days after design approval. With the 1-2 day design phase included, clinicians can plan for 7-8 business days total from submitting digital records to holding the finished prosthetic.
Rush services are available for urgent cases, and the permanent digital record means replacement cases ship faster than the original, often without any new clinical records if the patient's anatomy has not changed significantly.
Complete Workflow Timeline at a Glance
For clinical planning purposes, here is the complete digital denture manufacturing timeline:
- Day 0: Digital records submitted via scanner portal or AvaDent Dashboard
- Days 1-2: CAD/CAM design, Adaptive Occlusion processing, digital preview sent for approval
- Days 3-8: XCL milling, 3D scan QC verification, finishing
- Day 8-9: Free 2-day FedEx delivery to your practice
This compares favorably to conventional lab timelines of 3-5 weeks for complex cases, and it eliminates the unpredictable iteration cycles caused by remakes, relines, and extensive chairside adjustments.
How Digital Manufacturing Translates to Clinical Outcomes
The manufacturing differences described above produce measurable patient and practice benefits:
- Fewer appointments: AvaDent's Reference Denture Straight-to-Final workflow achieves case completion in 2 appointments and 60 minutes of total chair time. The 3-Appointment 90-Minute protocol covers more complex cases in three visits. Compare this to the 5-7 appointment sequences common with traditional methods.
- Reduced adjustments: Adaptive Occlusion and monolithic XCL construction eliminate the most common sources of post-delivery complaints, including occlusal discrepancies and tooth pop-offs.
- Better hygiene outcomes: The virtually porosity-free XCL surface resists bacterial colonization, reducing the incidence of denture-related stomatitis and improving long-term oral health.
- Reproducibility: Permanent digital records make replacement and duplication straightforward, a meaningful advantage for patients with active lifestyles or a documented history of prosthetic loss.
Over 250,000 patients served globally and 25+ peer-reviewed clinical studies spanning 2015-2024 validate these outcomes across diverse populations and case types.

Yes. AvaDent's streamlined workflows reduce treatment to 2-3 appointments for most cases. The Reference Denture Straight-to-Final protocol completes in 2 visits and 60 minutes of chair time. Even the most comprehensive 4-appointment protocol for new denture patients without an existing reference denture is substantially faster than conventional workflows requiring 5-7 visits.
Can I use any intraoral scanner to send records to AvaDent?
AvaDent integrates natively with seven scanner platforms: iTero, 3Shape Trios, Dentsply Sirona PrimeScan, Medit, Dexis, Shining 3D, and desktop scanners via STL upload. Practices using any other scanner can export STL files and upload them directly to the AvaDent Dashboard. Practices without an intraoral scanner can submit physical impressions for in-house digitization.
How does AvaDent ensure quality control on every denture?
Every finished prosthetic is 3D scanned and the scan data is compared computationally against the original approved digital design file before shipping. Units that fall outside tolerance are rejected and remilled. This 100% verification process, applied to every unit and not a sample, ensures the prosthetic you receive matches the design you approved.
