In short: With a digital scan and a milling unit in the practice, a ceramic crown, partial crown or inlay can be designed and fitted in one appointment. That removes the temporary crown, the second appointment and the waiting weeks. For complex cases, multiple teeth or demanding front-tooth aesthetics, a dental laboratory still produces the better result — the technician does things a milling unit cannot.
The conventional route to a crown has three parts: prepare the tooth, wear a temporary for two or three weeks, come back. The temporary is the weak point — it can come loose, it does not seal as well, and the tooth underneath stays sensitive. Removing that step is the actual benefit.
How it works
- The tooth is prepared as usual, under local anaesthetic
- A digital scan replaces the impression — no tray, no putty
- The restoration is designed on screen, and you can see it before it exists
- A milling unit cuts it from a ceramic block in the practice
- It is fitted, adjusted and bonded in the same appointment
You leave with the final restoration in place. There is no temporary and no second appointment, which for patients who travel or have inflexible working hours is often the deciding factor.
What it is good for
Single crowns, partial crowns and inlays on back teeth are the natural fit. The ceramic used is durable and colour-stable, the fit is precise because there is no impression material to distort and no transport, and the tooth spends no weeks under a provisional.
Where a laboratory is better
This is the part usually left out. A dental technician can layer ceramic by hand to reproduce the subtle translucency and internal colour of a natural front tooth — a milled block is one material throughout, and on a visible upper front tooth that difference is sometimes visible. For several adjacent teeth, for bridges, for full-arch work, and where the shade has to match neighbouring teeth exactly, the laboratory route produces the better result.
Our position is straightforward: a single back tooth in one appointment, yes. A front-tooth restoration where the appearance has to be right, laboratory. We say which applies to your case, and the reason.
Cost and cover
The material and the chairside process appear as their own items in your written cost plan, separated from the standard covered by statutory insurance, so you can see the difference rather than a single total. In-practice milling is not automatically more expensive than the laboratory route — but it is not automatically cheaper either, and we will not present it as a saving when it is not.
Frequently asked questions
How long does the appointment take?
Longer than a conventional preparation appointment, because the milling and fitting happen in the same visit. Plan for a longer single appointment rather than two shorter ones.
Is a milled crown as durable as a laboratory one?
For single back teeth, yes — the ceramics used are strong and colour-stable. The difference lies in aesthetics on visible front teeth, not in durability on molars.
Can a bridge be made this way?
Bridges and multi-tooth work belong in a laboratory. Chairside milling is for single restorations.
Does statutory insurance cover it?
Insurance covers the standard restoration for your finding. Ceramic and the chairside process are usually private, itemised in the cost plan before treatment begins.
