New Technologies in Dental Laboratories.
Laboratory marketing leans heavily on technology, and the claims are difficult to evaluate from outside. What follows is a framework rather than a product list.
Separate mature from emerging
Some digital laboratory technology is entirely settled. CAD design and subtractive milling of ceramics and metals have been in routine production for years, with well-understood behaviour and predictable results. A laboratory using them is not doing anything remarkable; one not using them would be unusual.
Other applications are maturing. Additive manufacturing is thoroughly established for models, custom trays, splints, provisionals and castable patterns, and is developing for definitive restorations, where the materials question is still open.
Others are genuinely emerging — algorithmic design assistance, some photogrammetric methods, certain novel materials. Emerging is not a criticism; it means the evidence base is thinner and early results are less predictable.
The question is what a technology changes for you
A laboratory listing equipment is telling you what it bought. What matters is what that changes about the restorations you receive.
Some technologies genuinely change outcomes: milling produces more consistent internal fit than casting for certain applications; digital design allows verification steps that were previously impractical; digital archiving allows remakes without re-appointing the patient.
Others change laboratory economics without changing your experience at all. That is legitimate — laboratories need to be viable — but it should not be presented as a clinical benefit.
Additive manufacturing, specifically
Printing is where most current claims concentrate, and it is worth being precise about what is settled.
Printed models, trays, surgical guides, splints and provisionals are well-established and perform predictably. Printed castable patterns are routine. What remains less settled is printed definitive restorations, where the material properties — strength, wear behaviour, colour stability over years — are still accumulating evidence relative to milled ceramics.
That is not an argument against it. It is an argument for knowing which category a given restoration falls into, and for asking rather than assuming.
Algorithmic design assistance
Software that proposes margins, anatomy and occlusal surfaces is becoming capable, and it genuinely speeds routine work.
The limitation is the same one that applies to every automated proposal: it produces a plausible answer from the data it is given. Where the margin is ambiguous in the scan, the software proposes a margin anyway, confidently and smoothly.
The useful question is not whether a laboratory uses design assistance but whether a technician reviews and modifies what it proposes. Automated design accepted without review is exactly how confident, wrong restorations get made.
Intraoral scanning is now the practice-side question
Scanner capability has advanced considerably, and for single units and quadrant work the technology is no longer the limiting factor — technique and tissue management are.
Full-arch accuracy remains the genuinely open question, which is why verification steps persist in implant workflows rather than having been designed away.
For a practice evaluating whether to adopt scanning, the honest framing is that it removes a category of error, adds a learning period, and does not reduce the need for clinical control of the field.
Questions that actually distinguish laboratories
What is made in-house and what is outsourced, and where. Whether a technician reviews automated design proposals. What is retained digitally, for how long, and whether a remake can be produced from an archive. Which restorations are produced by which method, and why that choice is made per case.
Those answers tell you something. A list of machine names does not.
A laboratory comfortable answering them plainly is generally the more reassuring signal, regardless of what the answers turn out to be.
The unchanged constraints
No technology recovers information that was never captured. A margin obscured at the moment of recording is not retrievable by any process, digital or otherwise. An occlusal relationship recorded with the patient not in maximum intercuspation produces a wrong result however it is manufactured.
Nor does technology substitute for judgement. Material selection, occlusal design and the decision to query a marginal case are all decisions, and they are made by people.
This is the reason the fundamentals in the rest of this section have not been superseded by any of it.
Materials move faster than methods
Most attention goes to equipment, but the more consequential changes over the past decade have been in materials. Higher-translucency zirconia formulations changed which cases monolithic restorations could serve. Improvements in adhesive chemistry changed what could be bonded and how reliably.
Material change is harder to evaluate than equipment because the claims are about long-term behaviour, and long-term evidence by definition takes time to accumulate. A formulation released two years ago cannot have ten-year data.
The reasonable position is neither to avoid new materials nor to adopt them universally, but to use them where their advantage is clear and the consequences of underperformance are manageable — and to keep well-evidenced options for cases where longevity is the governing concern.
What is worth asking before a technology changes your workflow
Some laboratory technology is invisible to a practice; some changes what you do at the chair. Only the second category warrants much of your attention.
Where a change would affect your workflow — a different submission method, a different record required, a different appointment sequence — the questions are practical. What does it require from us? What is the learning period realistically? What happens to cases during transition? Is there a fallback if it does not suit a particular case?
A laboratory proposing a change that affects your practice should be able to answer all four without hesitation. If the answers are vague, the change is probably not ready for your patients.
A note on being first
There is a real cost to adopting immediately and a real cost to adopting late. Early adoption means working through problems that later adopters never encounter; late adoption means forgoing benefits that were available.
For most practices the sensible position on laboratory technology is to care about outcomes rather than methods — consistency, fit, aesthetics, communication — and to let the laboratory make the equipment decisions it is better placed to make.
Where a technology genuinely changes your workflow, such as intraoral scanning, that is a different decision and one worth making deliberately.
In short
- Distinguish settled technology from emerging applications
- Ask what a technology changes about the restorations you receive
- Printed models and splints are established; printed definitive restorations are still maturing
- Ask whether a technician reviews automated design proposals
- No technology recovers information that was never captured
