Setting Up a Digital Dental Lab: Complete Guide
Short answer
Sequence matters when digitising a dental lab. A lab scanner and CAD software normally come first because they digitise the incoming work; then the milling machine; and for zirconia a sintering furnace. Starting with a milling machine before a scanner leaves the machine without any input to cut.
Moving from traditional methods to a digital dental lab is no longer a luxury — for any dental technician who wants faster turnaround, tighter accuracy and better quality, it's now a competitive necessity. This guide walks through what a digital lab is built from, in what order to buy, and what to watch for at each stage.
What does a digital dental lab actually mean?
In a digital workflow, physical impressions and wax modeling are replaced by a 3D file: the patient's (or model's) geometry is captured digitally, the restoration is designed in software (CAD), and then milled from a block of zirconia or another material (CAM). The result is better fit, higher repeatability and less human error.
Four pillars of a digital lab
1. Lab scanner (the digital input)
A lab scanner turns a physical impression or plaster model into an accurate 3D file and is the starting point of the whole chain. Scanner accuracy directly affects the quality of the final restoration. If you work with clinics that already have an intraoral scanner, you can receive files directly and cut down on re-scanning. See models on the lab scanner page.
2. CAD/CAM milling machine (the manufacturing output)
The production heart of the lab is the dental milling machine, which turns the digital design into a physical part. Axis count (4 or 5), wet or dry milling, and the range of materials it can process are the most important selection criteria. See models on the milling machines page.
3. Sintering furnace (final firing)
Milled zirconia is still in its "green," fragile state and must be fired in a sintering furnace to reach final strength and dimensions. Temperature uniformity and support for fast cycles are the two key criteria. See the sintering furnaces page.
4. Consumables: zirconia blocks and premill blanks
Choosing the right block matters as much as the machines themselves. Get to know the difference between white and multilayer zirconia, and for implant work, consider premill blanks.
What order should you buy in?
If your budget is limited, here's our suggested order:
Step one: milling machine + sintering furnace (the production core) — because they add the most value. Step two: a lab scanner, for full independence from physical impressions. Step three: upgrade software and add specialty materials. At the start, you can even outsource design and just handle milling and sintering in-house.
Important: an "open system" — in scanner and software output — lets you mix devices from different brands instead of getting locked into one closed ecosystem.
Setup cost and return on investment
Setup cost varies by brand and device tier, but the key metric is return on investment: by eliminating impressions, rework and outsourcing, cost per unit drops and production capacity rises. A well-run digital lab can recover its initial investment within a reasonable timeframe.
Dentiva recommendation
As a supplier of digital dentistry equipment, Dentiva offers the entire chain — from scanners and milling machines to sintering furnaces and zirconia blocks — CE-certified, with free consultation, installation and support across Iran.

Buying order: where to start
Buying the whole chain at once isn't necessary or even possible for most labs. The lowest-risk order looks like this:
Step one — scanner. It's the input to the whole chain and nothing else matters without it. With a scanner you can start designing and temporarily outsource milling.
Step two — milling. Once the volume of outsourced milling work costs more than a machine payment would, it's time to buy. This is also when you decide between 4 and 5 axis, with a multi-year horizon in mind.
Step three — furnace. It becomes necessary right after milling, since a milled part can't be delivered without sintering.
What gets forgotten in the initial plan
Air compressor for most milling machines — extra space, noise and maintenance.
Power and ventilation — the furnace and milling machine have their own requirements that need to be checked before delivery.
Consumables — liquid stains and glaze powder are the smallest line item but have the biggest effect on final appearance.
Training time — the difference between a lab that's producing within the first month and one still struggling after three is almost always training, not the model of machine.
Frequently asked questions
Which machine should I start with?
The scanner. It's the input to the chain, and with it you can start designing while temporarily outsourcing milling until work volume justifies buying a mill.
When is it time to buy a milling machine?
When the monthly cost of outsourced milling exceeds the payment or upkeep cost of owning a machine. Until then, outsourcing is the smarter economic choice.
What costs are usually missing from the budget?
Air compressor, power and ventilation requirements, consumables, and team training time. These typically fall out of the initial plan.
Any advice for a small space?
Machines that don't need a separate compressor make setup in a tight space noticeably easier. Get in touch for advice on laying out your space.
Key takeaways
- Start with a scanner and software, not with the milling machine.
- Milling without a source of digital files is idle capacity.
- For zirconia, a sintering furnace is an inseparable part of the chain.
- Count technician training as part of the equipment plan, not an afterthought.
- Space, power and ventilation are what the initial plan usually forgets.
