Take an impression, send it to the lab, come back in two weeks — that was the old routine.
Now your restoration is milled right where you sit —
at the chair.
Seongmo Dental Clinic has brought the Dentsply Sirona CEREC Primemill in-house, milling ceramic blocks directly from your Primescan data. The two weeks you used to spend in a temporary crown now takes about as long as a cup of coffee.
Seongmo Dental Clinic — CEREC Primemill Chairside Milling in Seoul
CEREC Primemill is Dentsply Sirona’s chairside milling unit — a CAD/CAM system that precision-mills ceramic and zirconia blocks to the digital design right inside the clinic, producing crowns, inlays, onlays and endocrowns the same day. Seongmo Dental Clinic runs the Primemill together with the SpeedFire sintering furnace, completing restorations entirely in-house — no outside dental lab.
The old routine of impression → dental lab → two-week wait becomes scan → design → mill → same-day seating.
The Primemill at our clinic,
what exactly does it do?
CEREC Primemill is a chairside milling unit that precision-cuts ceramic and zirconia blocks from digitally designed restoration data. Seongmo Dental Clinic keeps it in-house to produce crowns, inlays and endocrowns the same day.
Conventionally, an impression of your tooth was sent to an outside dental laboratory, and it took 1–2 weeks for the finished restoration to come back — weeks you spent coping with a temporary tooth. The CEREC Primemill that Seongmo Dental Clinic has introduced brings that entire process into the treatment room. It is a CAD/CAM milling unit: data captured with the Primescan 3D scanner is designed into a restoration on screen, and the Primemill then mills a ceramic block to that exact design.
Key features of the Primemill
Milling and grinding in one — every material covered
Integrated touchscreen — intuitive in-house operation
One seamless flow with Primescan and SpeedFire
The Primemill is not just a milling machine — it is the heart of an in-house digital restoration system that goes from scan to seating within a single day.
Same-day restorations with the Primemill,
how is it done in a single day?
Seongmo Dental Clinic processes Primescan scanning, Primemill milling and SpeedFire sintering consecutively in-house, so crowns and inlays can be fabricated and seated the same day — no outside lab involved.
The key to same-day restorations is eliminating the time spent shuttling to and from a dental lab. Seongmo Dental Clinic keeps the Primemill in-house and handles scanning, design, milling and sintering in one place. The discomfort of rubber impressions, the hassle of wearing a temporary crown for two weeks, and the risk of an ill-fitting restoration going back to the lab are all minimized.
What same-day treatment changes
No more temporary-crown troubles
Less gagging, fewer return visits
Permanent data storage for follow-up care
That said, depending on gum condition and case complexity, same-day completion is not always possible. Seongmo Dental Clinic gives you an honest answer after a thorough examination.
Primemill restorations,
can I trust the precision and materials?
The Primemill offers among the highest machining precision of any chairside unit, and Seongmo Dental Clinic uses only verified genuine blocks such as lithium disilicate, zirconia and CEREC Tessera.
Speed means nothing without precision. The Primemill mills ceramic blocks from Primescan’s high-precision scan data, minimizing the gap between restoration and tooth. The tighter that seam, the lower the risk of secondary decay — and the longer your restoration lasts. Seongmo Dental Clinic treats it as a clinical standard that the Primescan–Primemill digital workflow reduces error compared with rubber impression techniques.
About materials and precision
CEREC Tessera — advanced high-strength lithium ceramic
Margin precision = restoration lifespan
Stronger bonding with ACTILINK surface activation
Fast, yet precise, with verified materials. Seongmo Dental Clinic never trades quality for speed.
Same-day Primemill restorations,
how does the visit proceed?
Same-day restoration at Seongmo Dental Clinic follows five steps — scan, design, milling, sintering and seating — all performed in-house.
- 01Primescan 3D scanYour mouth is scanned in 3D — no rubber impressions — to capture precise digital data.
- 02Restoration designCrowns, inlays and endocrowns are designed on screen from the scan data.
- 03Primemill millingThe selected ceramic block is precision-milled to the design. Zirconia takes about 5 minutes in Superfast mode.
- 04SpeedFire sintering & glazingZirconia and ceramics are fired in the high-speed sintering furnace and polished to a glaze.
- 05Bonding & seatingPrecision bonding after ACTILINK surface activation. The bite is adjusted and seating is completed the same day.
All five steps happen inside Seongmo Dental Clinic, connected within a single day.
Conventional restorations vs. Primemill same-day restorations
Here is how Seongmo Dental Clinic’s Primemill same-day workflow differs from the conventional outside-lab method.
| Comparison | Conventional | Seongmo Primemill |
|---|---|---|
| Impression | Rubber impression material | Primescan 3D scan |
| Fabrication site | Outside dental lab | In-house milling & sintering |
| Turnaround | 1–2 weeks | Same daywhen indicated |
| Temporary crown | Required | Minimized |
| Return visit | Required for seating | Seated same day |
| Data storage | Plaster models | Digital, kept permanently |
Primemill glossary
- CEREC Primemill
- Dentsply Sirona’s chairside milling unit. Mills ceramic and zirconia blocks to the digital design, producing crowns, inlays and endocrowns the same day.
- CAD/CAM
- Digital restoration fabrication combining computer-aided design (CAD) with computer-aided manufacturing (CAM). Designed from scan data and milled automatically by the unit.
- Chairside
- Fabricating restorations right beside the treatment chair — inside the clinic — rather than at an outside lab.
- CEREC Tessera
- Dentsply Sirona’s advanced lithium disilicate ceramic block. High strength with natural esthetics.
- Endocrown
- A one-piece ceramic restoration for teeth after root canal treatment. Preserves tooth structure and can be precision-made with the Primemill.
- Glazing
- Finishing a milled ceramic surface with a smooth gloss. Handled together with sintering in the SpeedFire.
Primemill same-day restorations — frequently asked questions
Can I really get a crown in one day with the Primemill?
Seongmo Dental Clinic processes Primescan scanning, Primemill milling and SpeedFire sintering consecutively in-house, so when your case is suitable, crowns and inlays are fabricated and seated the same day. Depending on gum condition and case complexity, an additional visit may occasionally be needed — we will let you know after a thorough examination.
Is same-day quality inferior to lab-made restorations?
The Primemill mills ceramic blocks from Primescan’s high-precision scan data and uses verified, genuine high-strength blocks such as CEREC Tessera. The high margin fit reduces the risk of secondary decay, and material strength is fully suitable for molar restorations.
How long does zirconia milling take on the Primemill?
In Superfast mode, the Primemill machines one zirconia crown in roughly 5 minutes. After SpeedFire sintering, same-day seating is possible.
What restorations can the Primemill make?
Crowns, inlays and onlays, endocrowns, laminates and implant restorations, among other ceramic prosthetics. Materials — zirconia, lithium disilicate, hybrid ceramics — are chosen to suit each case.
I gag easily — does the Primemill workflow use rubber impressions?
No. The Primemill workflow replaces impressions with the Primescan 3D intraoral scanner. Because your mouth is scanned digitally, there is none of the gagging or discomfort of rubber impression material.
How much does a same-day Primemill restoration cost?
Costs vary with the material (type of zirconia or ceramic) and the condition of the tooth. We provide exact figures in a consultation after a detailed examination — Seongmo Dental Clinic discloses its standard fees transparently.
