The Cost of Complexity: Why Dentures Don't Have to Start From Scratch

Complete dentures are one of the oldest treatments in dentistry. So why can they still require so much work to deliver?

A conventional complete-denture workflow may spread information gathering across preliminary impressions, definitive impressions, record bases and occlusion rims, jaw relations, tooth setup, try-in, processing, delivery, and adjustment.

Those procedures were developed for reasons. But there is an important difference between preserving a clinical principle and preserving every step traditionally used to accomplish it.

That distinction matters because every additional step has a cost. There is chair time, staff time, laboratory time, materials, scheduling, shipping, and the possibility of another round trip between the clinic and laboratory.

The patient pays a cost too. Another appointment may mean another day away from work. Another caregiver coordinating transportation. Another trip from a nursing facility. Another long drive for someone who doesn't live close to a dental provider.

For some patients, those aren't inconveniences. They're barriers.

Edentulism Hasn't Disappeared

According to the CDC's 2024 Oral Health Surveillance Report, 15.2% of Americans age 65 and older were edentulous in the 2017–March 2020 NHANES data. The prevalence increased from 11.4% among adults ages 65–74 to 19.7% among those 75 and older.¹

But the averages don't tell the whole story.

Among adults 65 and older, complete tooth loss affected 29.8% of those in the CDC's high-poverty group compared with 11.8% in its low-poverty group. It affected 33.4% of adults with less than a high school education compared with 8.8% of those with education beyond high school.¹

The people who need complete dentures are not distributed evenly across the population. Neither is their ability to absorb the time and expense involved in receiving them.

No denture workflow is going to solve poverty, transportation problems, workforce shortages, or the broader access-to-care problem. But those realities should make us willing to question complexity that no longer earns its place.

What Does a Denture Actually Need From Us?

Strip away the trays, rims, articulators, scanners, printers, software, and laboratory prescriptions for a moment. The fundamental problem becomes much simpler.

We need an accurate representation of the denture-bearing tissues. And we need to put teeth in the right place.

For the maxillary arch, that means establishing esthetics: midline, incisal edge position, anterior-posterior position, occlusal plane, lip support, and the relationship of the teeth to the face.

For the mandibular arch, we need an appropriate relationship to the maxillary arch, including vertical dimension and occlusion. Those are principles.

A wax rim is a tool. A custom tray is a tool. A scanner is a tool. The tool matters only to the extent that it helps us establish the information we need.

That raises a more useful question than whether a denture workflow is conventional, analog, digital, or hybrid: how many separate procedures do we actually need to collect, verify, and transfer that information?

Simplification Is Not the Same as Skipping

This question has been studied.

In a multicenter randomized controlled trial involving 64 edentulous participants, a simplified complete-denture protocol reduced clinical time and the number of clinical sessions by 34% compared with the conventional method. Laboratory returns decreased by 46.5%. Participant satisfaction and prosthodontist ratings of denture quality were comparable between the groups.²

Another randomized trial examined the economics of a simplified protocol. Median operator time decreased from 284.5 minutes with the conventional method to 173.2 minutes with the simplified method. Median direct treatment cost was 34.9% lower.³

Neither study evaluated RapidArches, SetTray, or SetArch. That distinction matters.

What they demonstrate is a broader principle: additional procedures do not automatically produce better treatment.

The objective shouldn't be to remove steps because fewer sounds better. It should be to determine which steps generate necessary clinical information, and which primarily exist because the traditional workflow requires that information to be transferred, reconstructed, and verified somewhere else. Simplification is not the same as skipping.

The Denture Is Also an Information-Transfer Problem

Consider what happens in a traditional denture sequence.

• The clinician makes an impression.
• The laboratory creates a model.
• Record bases and occlusion rims return to the clinician.
• The clinician uses those rims to establish tooth position, vertical dimension, and jaw relationships.
• That information goes back to the laboratory.
• A technician interprets it and sets teeth.
• The setup returns to the clinician.
• The clinician and patient evaluate whether the tooth position created at the laboratory accurately represents what was intended at the previous appointment.
• Then the case returns to the laboratory again for processing.

There are patients and situations where that sequence is entirely appropriate. But look at what is happening to the information.

We establish it. Represent it indirectly. Transfer it. Interpret it. Reconstruct it. Send it back. Verify it. And send it away again.

Every transfer requires work. Every reconstruction creates another opportunity for interpretation. Every return to the chair requires something else from the patient. What if more of that information could be established definitively while the patient was still sitting in front of us?

Maybe the Arch Doesn't Need to Start From Scratch

This is where the idea behind RapidArches becomes interesting.

Conventional dentures aren't entirely custom to begin with. We have used manufactured denture teeth, established arch forms, occlusal schemes, average dimensions, and tooth-arrangement principles for generations. We then use those standardized components and principles to create something individualized for the patient.

RapidArches pushes that idea one step further: replace custom arch fabrication with arch selection.

3 shapes

Tapered, round, and square.

3 sizes

Small, medium, and large.

9 forms

Nine arch forms in maxillary and mandibular versions.

Instead of constructing every arch tooth by tooth from the beginning, the clinician selects the geometry that most closely fits the patient and customizes from there. Standardized does not mean one-size-fits-all. It means starting closer to where you intend to finish.

That selected geometry can then follow the case through the RapidArches workflow. The arch selected clinically corresponds with other components built around the same form. For a dual-arch patient, that means selecting the appropriate maxillary and mandibular arches rather than fabricating both arrangements from zero. The distinction is subtle but important: selection is not the opposite of customization. Selection is the starting point for it.

Establish the Tooth Position While the Patient Is Still There

SetTray applies that concept to the clinical appointment. The impression tray incorporates a repositionable printed arch, allowing the clinician to position the proposed teeth relative to the patient's face and opposing arch.

Esthetics can be evaluated chairside. Vertical dimension can be established. Occlusion can be evaluated. The definitive impression can be made.

Most importantly, the clinician isn't trying to communicate all of that indirectly to someone who wasn't in the room. The patient can also evaluate the proposed tooth position where it matters most — not on a model and not on a computer screen, but in the context of their face.

Once that information has been established, the corresponding SetArch carries the selected tooth arrangement into the laboratory. Instead of asking the technician to reconstruct the clinical intent tooth by tooth, the arch itself becomes part of the information transfer.

The Laboratory Doesn't Have to Rebuild What the Clinician Already Established

SetArch is fabricated from dual-cross-linked PMMA and incorporates 13 layers of natural gradient within the tooth material. But the material story is only part of its role.

The larger workflow advantage is that the laboratory receives the tooth arrangement as an arch, rather than receiving records from which the arrangement must first be recreated with individual denture teeth.

The clinical decision travels with the case. SetArch can then be processed with a compatible PMMA denture-base material. During appropriate processing, the PMMA tooth arch chemically bonds with the PMMA denture-base material, creating a monolithic PMMA denture.

That distinction deserves some attention. Monolithic does not necessarily mean the entire denture began as one homogeneous block of material. Here, two PMMA materials serve different purposes and become chemically integrated during processing into the finished prosthesis.

More importantly for this discussion, the laboratory doesn't have to dismantle the selected arch concept just to build it again. The tooth position established clinically moves toward the finished denture with fewer translation steps in between.

We Put the Workflow to Work With Dr. James Piper

I recently had the opportunity to work with Dr. James Piper, a board-certified maxillofacial prosthodontist, on a maxillary and mandibular complete-denture case using SetTray and SetArch. We later presented the case during our Made to Measure webinar.⁴

The patient was 28 years old and completely edentulous.

Dr. Piper was trained in the same classical Air Force prosthodontic environment that taught many of us to approach complete dentures through a comprehensive, multi-appointment sequence. For this patient, he took a different route.

His team selected the appropriate SetTray forms. He verified the selection clinically and positioned the maxillary arch using the same facial and prosthodontic references he would normally use. The interarch relationship was established, and the impressions were made.

The clinical principles didn't disappear. Dr. Piper could still border mold according to his preferred technique. He still evaluated the tissues, tooth position, esthetics, vertical dimension, and occlusion. The patient still had the opportunity to see and approve the proposed tooth position.

What changed was the number of separate procedures needed to arrive at that information.

The dentures were delivered at the second visit. For this particular case, Dr. Piper estimated approximately 45 minutes of total chair time between the two appointments.

One case does not establish that every complete denture can — or should — be treated in two visits. Nor should it.

But something else from that case deserves more attention than the delivery time.

The patient was a young mother with a work schedule. Fewer appointments mattered to her.

During the webinar, Dr. Piper connected that experience to another population he regularly treats: nursing-home residents, including patients dependent on wheelchairs and others for transportation. For those patients, getting to the dental office may be considerably harder than sitting through the appointment once they arrive. That changes the value of an appointment.

What Are We Actually Saving?

This is where the economics become tempting. Fewer appointments. Less chair time. Less laboratory setup. Fewer handoffs.

It would be easy to jump from those observations to a claim that this produces a cheaper denture. We don't have the evidence to say that.

Published randomized trials demonstrate that simplified complete-denture protocols can reduce clinical time and, in some protocols, direct treatment costs.²˒³ But those studies did not evaluate SetTray and SetArch. We therefore should not assume that the same percentage savings apply here.

We also shouldn't assume that reducing the cost of delivering treatment automatically reduces the fee paid by the patient.

What workflow efficiency creates is opportunity. A dentist can use chair time differently. A laboratory can reduce procedures that consume technician time. A patient may make fewer trips. A practice or laboratory may ultimately decide how those efficiencies affect its economics.

Whether those savings translate into lower patient fees requires evidence we do not yet have. That's a question worth studying rather than a claim worth guessing about.

New Technology Isn't Automatically a Simpler Workflow

There's another trap here. It would be easy to turn this into an analog-versus-digital argument. It isn't one.

Recent evidence on digital complete dentures illustrates why. A 2025 systematic review evaluating conventional, hybrid, and digital complete-denture fabrication found evidence that digital and hybrid approaches can reduce clinical and laboratory time.⁵ Yet a more recent systematic review and meta-analysis found no statistically significant difference in laboratory, clinical, or total costs between digital and conventional workflows across the studies it analyzed.⁶ Operator experience also affected clinical cost and treatment sessions.

The literature is evolving, but the message is useful. Technology and efficiency are not synonyms. If we take five traditional procedures and recreate all five on a computer, we may have digitized the workflow without simplifying it.

Digital tools can be extremely valuable. So can analog ones. And often the strongest workflow is hybrid. The better question is whether each tool preserves the clinical information we need while reducing unnecessary work around it.

The Goal Isn't a Two-Day Denture

Rapid delivery makes a good headline. It shouldn't be the principle. Speed serves the patient only when the information required for appropriate treatment has been preserved.

Some patients will need additional appointments. Some will need a conventional try-in. Some will require tooth arrangements that fall outside an available arch form. Anatomy, esthetic demands, occlusal relationships, neuromuscular considerations, previous prostheses, patient expectations, or other clinical factors may justify a more individualized sequence.

That isn't a failure of simplification. It is clinical judgment.

The goal isn't to force every patient through fewer appointments. The goal is to stop forcing every patient through appointments that aren't adding necessary information. There is a meaningful difference.

Customize What Needs to Be Customized

Dentistry tends to associate customization with quality. Sometimes that's justified. Sometimes we are custom-fabricating something simply because custom fabrication is how we've always gotten to the final result. Those aren't the same thing.

RapidArches asks us to separate three ideas that are often treated as one: fabrication, selection, and customization.

• If an appropriate arch form can be selected, why fabricate it from scratch?
• If tooth position can be evaluated directly in the patient's face, why communicate it indirectly and ask someone else to reconstruct it before we evaluate it again?
• If a laboratory can receive the geometry already established clinically, why introduce another setup step unless the patient actually needs it?

None of those questions argues for lowering the standard of care. They argue for identifying where the value actually resides.

Complete-denture treatment will always require judgment. It will always require an understanding of anatomy, esthetics, occlusion, impression principles, tooth position, and the patient sitting in front of us.

Those are the parts we should protect. The rest should be allowed to evolve.

If we want dentures to become easier to deliver — and perhaps, eventually, more accessible — we may be asking the wrong question when we start with how to make the denture cheaper. A better place to begin may be this: why are we still custom-building everything around it?

Nine arch forms. One selection that carries the case.

RapidArches puts SetTray, SetArch, MonoArch, and ReadyArch on the same nine forms, so the geometry you choose for a patient follows the case from the chair into the laboratory.
