One-Day Crown Guide
Finished With One Anesthesia, No Temporary Tooth
A one-day crown is made by carrying out the intraoral scan, design and milling inside the clinic, so the restoration is finished in a single day without a temporary crown.
It reduces anaesthesia and the number of visits, no extra fee is charged for same-day work, and the material is chosen from hybrid, Tessera, zirconia or e.max according to the tooth position and biting force.
Two or three visits for one crown, with a temporary tooth falling out in between — does it really have to be that way?
Seongmo Dental completes the entire scan, design, milling, sintering, and fitting process in-house in a single day.
Here is a summary of the time required by material, which cases are possible, and the cost.

01What Is a One-Day Crown/Prosthetic
Crowns and inlays that cover a tooth after decay or root canal treatment usually proceed like this: taking an impression, attaching a temporary tooth, then returning 1–2 weeks later for fitting.
If the temporary tooth falls out in between, another visit is needed. A same-day prosthetic is a treatment that compresses this process into a single day.
From scan → design → milling → sintering → fitting, the entire process is completed in-house while the anesthesia is still active.
Some places advertise “same-day prosthetics” in name only while actually outsourcing to an external lab.
For it to be truly same-day, the scanner, milling equipment, and sintering furnace must all be in-house .
Seongmo Dental has this full system, and depending on the material, everything from scanning to fitting is completed within a 25–50 minute chair time.
There are three conditions for same-day prosthetics: ① an in-house digital scanner (taking impressions without impression material), ② in-house milling equipment (carving the prosthetic), and ③ an in-house sintering furnace (firing zirconia).
If even one relies on an outside party, “same-day” is not possible.
02What Are the Benefits of Finishing in One Day Without a Temporary Tooth
Being fast is not everything. When the temporary-tooth period disappears, there are things that change clinically.
- Finished With a Single Anesthesia — Since tooth preparation and fitting finish within a single anesthesia, there is no burden of anesthesia or pain for a second visit.
- Zero Temporary Tooth Trouble — There is fundamentally no temporary tooth falling out, sensitivity from temporary cement leakage, or gum inflammation around a temporary tooth.
- Reduced Risk of Secondary Infection — The exposure time of the prepared tooth is reduced to a few hours, reducing the chance for bacteria to invade in that time.
- Half the Number of Visits — This makes a real difference for busy office workers, those coming from far away, or those with dental anxiety.
- Precision — Instead of holding impression material in the mouth while it sets, digital scanning with about 20μm precision means even those with a strong gag reflex can comfortably have an impression taken.
03Seongmo Dental’s One-Day Full System
Seongmo Dental’s one-day prosthetics are based on the CEREC system from Dentsply Sirona of Germany.
| Equipment | Role | Point |
|---|---|---|
| Primescan | Intraoral Digital Scan | About 20μm precision, impressions without impression material |
| Inlab AI Design | Prosthetic Design | Biogeneric design support based on thousands of clinical cases |
| Primemill | Milling (Carving) | 4-motor independent drive — about 2 min for hybrid block, about 12 min for Tessera, about 5 min for zirconia |
| SpeedFire | Sintering (Firing) | Zirconia sintering about 10–14 min — the conventional lab method takes 8–12 hours |
Among these, in particular the SpeedFire sintering furnaceis the core of same-day treatment.
Zirconia must be fired at high temperature after milling to reach its final strength, a process that takes more than half a day at a lab.
The induction-heated SpeedFire reduces this to about 10 minutes, making same-day completion of zirconia crowns possible.

04Time Required and Features by Material
| Material | Total Time (Scan to Fitting) | Features | Main Use |
|---|---|---|---|
| Hybrid Block (LAVA Ultimate, VITA Enamic) | About 10 min | Resin + ceramic composite, elastic shock absorption | Inlays, small restorations |
| CEREC Tessera | About 25 min | Reinforced glass ceramic, balance of aesthetics and strength | Crowns, onlays, endocrowns |
| Zirconia (CEREC MTL) | About 25 min | Highest strength, handles molar chewing force | Molar crowns |
| e.max CAD | About 40 min | Lithium disilicate with excellent aesthetics | Aesthetic-area crowns |
The carving method also differs by material. Glass ceramics are wet-milled with water spray, while zirconia must be dry-milled to preserve its properties.
Since Primemill supports both methods, the material can be chosen to fit each case.

05Not Just Crowns — Inlays, Onlays, and Endocrowns
The real value of the same-day system is being able to confidently recommend prosthetics that remove less tooth structure.
- Inlay — Precisely hollowing out and fitting only the decayed area. Completed same-day.
- Onlay/Overlay — An intermediate step that covers the chewing surface without shaving down the entire tooth. Preserves a tooth that was about to become a crown case, more conservatively.
- Endocrown — For a tooth with enough remaining structure after root canal treatment, this is bonded inside the tooth without full removal. This option is only possible with reinforced ceramics like Tessera and an in-house fabrication system.
- Crown — Standard protection when little tooth structure remains. Molars mainly use zirconia.
Rather than “a big cavity always means a crown,” Seongmo Dental’s principle is to look at how much tooth structure remains and review from the most conservative method first, in the order Inlay → Onlay → Endocrown → Crown . Related article: Same-Day Inlays and Crowns — SpeedFire Sintering
06The Same-Day Process
Diagnosis and Treatment Planning
We check the extent of decay and cracks with low-dose 3D CT and Q-ray fluorescence analysis, and decide on the most conservative prosthetic form.
Tooth Preparation After Anesthesia
After topical anesthesia then i-ject computer-controlled anesthesia to reduce the pain burden, only as much of the tooth as necessary is removed.
Primescan Digital Scan
Scanning with about 20μm precision, without impression material. Finished in a few minutes with no gag reflex concerns.
Design → Milling → Sintering
After AI-assisted design, Primemill carves the prosthetic, and zirconia is sintered in the SpeedFire for about 10 minutes. You can simply rest during this time.
Fitting and Bite Adjustment
Fitting is done before the anesthesia wears off, with fine bite adjustment. Since the design data is kept on file, quick remaking is possible if damaged.
07Cost and Warranty
Prosthetics such as crowns and inlays are non-covered procedures. Seongmo Dental fully discloses fixed, itemized fees, and the cost varies by material (hybrid/Tessera/zirconia/e.max) and prosthetic form.
The exact amount can be checked in the Non-Covered Fee Guide, and we provide the total cost after diagnosis.
- Bonded-fill resin (elastic composite resin) for cavities comes with a 5-year free warranty — restored again within warranty coverage if it comes off
- Digital prosthetic design data kept on file — reduces the time and cost burden of remaking if damaged
- No additional cost for same-day treatment — we do not charge more for doing it quickly
08Especially Well Suited For
- Office workers who find it hard to take a day off — treatment completed with a single half-day off
- Those coming from far away — turns two trips into one
- Those with a severe gag reflex — digital scanning without impression material
- Those whose temporary tooth kept falling out — there is no temporary-tooth stage at all
- Those with dental anxiety — finished with a single anesthesia, a single visit
When gum inflammation is severe, when root canal treatment must come first, or when multiple teeth need restoration at once, it is safer to split the process into stages.
Whether same-day treatment is possible is judged after diagnosis, and accurate treatment always takes priority over forcing same-day completion.
09Frequently Asked Questions
Can a crown really be finished in a single day?
Isn’t something made in one day made carelessly?
What materials are used?
Isn’t it more expensive?
Can a tooth that has had root canal treatment also get a same-day crown?
I have a severe gag reflex, so I’m afraid of taking impressions.
Isn’t the lifespan of a same-day crown shorter?
Can inlays also be done same-day?
If a Crown Has Kept You From Coming In Multiple Times
A single half-day off is enough. We check everything from diagnosis to same-day feasibility in one visit.
