Digital Dentures: What to Send, and How the Lab Workflow Actually Runs
A denture is the only restoration where the lab is designing an entire bite from records alone - no prepared tooth, no implant position, no adjacent dentition to copy. That makes record quality everything, and it makes the digital workflow genuinely better than analogue, not just faster. Here is what to send and what happens to it.
Short answer: a digital denture case lives or dies on two records - the tissue-bearing surfaces (scanned or impressed accurately) and the jaw relation (vertical dimension plus centric, captured against a stable reference). Get those right and the digital workflow compresses the calendar dramatically, because design iterations happen in software instead of in a second chairside appointment. Get them wrong and no scanner saves the case.
We produce full and partial dentures digitally, and the first thing worth saying is what digital dentures actually change. The impression does not disappear - edentulous ridges still have to be captured with functional precision. What changes is everything after capture: base design, tooth arrangement, try-ins and revisions all move into software, where a change costs minutes instead of a new appointment. The records, ironically, become *more* important, because they are now the only analogue step in the chain.
Why dentures are a different category of case
Every restoration in the rest of this blog copies, replaces or supports something clinically measurable: a prepared tooth, an implant position, an adjacent dentition. A complete denture copies nothing. The lab is designing tooth position, vertical dimension, occlusal plane, and aesthetics entirely from records and reference points - the patient's old denture, photos, a bite rim, the ridge anatomy. Three consequences follow:
- The record set defines the outcome ceiling - a lab can only design as well as the records allow, which is why this post spends most of its length on records
- Try-ins are not optional ceremony - a try-in is the design being verified against the actual patient, and for dentures it is where phonetics, lip support and midline get confirmed
- Communication replaces copying - 'like the previous denture but whiter' is a complete aesthetic brief for a crown case; for a denture it is a starting point, not a specification
The records a digital denture case needs
| Record | What it does | What the lab cannot do without it |
|---|---|---|
| Primary + definitive impressions (or scanned definitive cast) | Captures the tissue-bearing surfaces with border moulding where indicated | Design a stable, retentive base - the single most common source of denture complaints |
| Jaw relation record (VDO + centric) on a stable rim or a scanned gothic arch | Fixes vertical dimension and the inter-arch relationship | Anything: without a verified VDO the entire occlusion is an assumption |
| Existing denture (physical or scanned), if the patient has one | Encodes tooth position, polish surface contour and phonetics the patient already tolerates | Preserve a working outcome; scanning the old denture is the highest-value five minutes in the case |
| Face photos: smile, profile, repose | Plans incisal display, lip support, midline and smile line | Plan aesthetics - photos are the difference between designed and guessed |
| Tooth mould and shade direction | Directs mould selection and characterisation | Match expectations; 'natural looking' needs a reference, not an adjective |
| Special instructions: flanges, tori relief, post dam, border extensions | Encodes anatomy the scan may not show | Avoid border over- or under-extension at delivery |
One emphasis worth repeating: scan the patient's existing denture if one exists, even if the case is a remake. It is a proven template for tooth position and polished surface contour - the two things patients judge first and clinicians cannot see from the ridge alone. A case arriving with the old denture scanned starts from an accepted baseline; a case arriving without one starts from a discussion.
The digital workflow, stage by stage
1. Intake and record audit
The lab checks the record set the way a full-arch audit works: impressions complete and border-moulded where indicated, jaw relation captured against a stable reference, aesthetics briefed. Expect clarifying questions within a day. For dentures more than any other case type, a question asked at intake is a chairside appointment saved at delivery.
2. Design in software
Base design against the scanned anatomy (relief areas, post dam, border contours), then tooth arrangement against the jaw relation and the aesthetic brief. The design file is the new wax try-in's parent: this is the stage to request changes, because a design revision is minutes of CAD time rather than a reset appointment.
3. Try-in - printed or milled base with set-up teeth
The case comes back to the chair for verification: fit and retention of the base, VDO and centric in the mouth, midline and incisal display against the face, phonetics ('sixty-six' and 'fifty-five' still catch the errors patients notice at dinner). This is the stage where the patient's real opinions enter the record. A lab that discourages try-ins on complete dentures is optimising its calendar at your patient's expense.
4. Final production
Approved design moves to the final material - milled PMMA or printed resin, see below - then finishing, polish, and QC: articulation check, base thickness consistency, surface finish, and photo documentation where the account expects it.
5. Delivery with the records that matter
The final denture should ship with the design file reference, material and lot documentation, and remount information if the case was articulated. If a post-delivery adjustment conversation starts, that documentation is where the diagnosis begins - the same logic as any other case, and the reason written records beat verbal ones.
Milled or printed: the material question in dentures
| Approach | Where it fits | Trade-off to accept |
|---|---|---|
| Milled PMMA (pre-polymerised puck) | High-demand cases needing density, polish retention and low porosity | Material cost and waste - a puck is carved, not grown |
| Printed resin (base + teeth or monolithic print) | Fast turnaround, cost-sensitive cases, easy remake cycles | Surface porosity and colour stability depend heavily on post-processing discipline |
| Printed try-in + milled final | The common hybrid: iterate cheaply, deliver densely | Two material systems on one case - records must carry over cleanly |
| Printed base + compatible denture teeth | Cases wanting physical teeth on a digital base | Bonding protocol matters; ask which tooth system the lab pairs with which resin |
The honest framing: printing has won the iteration economy (try-ins, duplicates, spares) while milling retains the edge in final-restoration density and polish stability. Most well-run workflows use both in sequence, and the question to ask a lab is not 'printed or milled' but 'what is your post-processing discipline for printed parts' - wash parameters, cure times, and whether the protocol is written or improvised. Post-processing is where printed denture failures are born.
Where digital denture cases actually fail
What makes a digital denture account run smoothly
- A standing record protocol - same impression technique, same jaw relation method every time, so the lab's design assumptions never reset between cases
- The old denture, always scanned - it is the aesthetic and functional baseline no verbal brief can replace
- Photo discipline - repose, smile, profile, at case intake; three photos prevent the most expensive category of remake in the chart above
- Try-in dates planned as appointments - like full-arch verification stages, try-ins that are 'when it comes back' are where calendars slip; the same arithmetic as the turnaround guide
- One named coordinator - denture cases accumulate preferences (flange depth, tooth mould, characterisation) that only survive in an account, not in a case file; this is the same preference-profile argument from the evaluation checklist, at its most important
If you are weighing whether to send denture work overseas at all, the same rules apply as any case: written policies, a try-in in the plan, and a pilot on a genuinely representative patient. Our pages on full dentures, partial dentures and removable restorations cover the product side; and if you want the pricing conversation to start from your actual case mix, request pricing with the record set described above and the quote will be specific instead of generic.
