Those five minutes biting down on a mouthful of rubber, trying not to gag.
Now we scan your mouth and
look at it together on screen.
Seongmo Dental Clinic uses Primescan, a premium intraoral scanner priced around ₩30 million. It captures millions of data points per second to reproduce even fine contours in 3D, and this data flows directly into PrimeMill milling, 3D printing, and implant guide fabrication.

Every difference in the outcome starts with a perfect original data set. Without an accurate original, everything precise that follows loses its meaning.
Sungshin Univ. dental 3D intraoral scanner —
what does it actually do?
Primescan is an intraoral scanner that optically scans the mouth to turn the shape of teeth and gums into 3D data. Instead of rubber impression material, Seongmo Dental Clinic designs prosthetics, orthodontic appliances, and surgical guides from this scan data.
In dental treatment, a prosthetic's fate is largely decided at the very first step. If even a slight distortion occurs while taking the impression, that error carries straight through design, fabrication, and fitting. To make a precise prosthetic, getting the most accurate original from the start matters more than anything else.
This is why Seongmo Dental Clinic insists on Primescan, a premium device priced around ₩30 million. It goes beyond simply replacing rubber impressions — it's core technology that raises the precision, speed, and patient satisfaction of the entire treatment process together.
3D Intraoral Scanner Core Technology
Overwhelming Precision
Unmatched Comfort
Transparent Care You Can See
A comfortable start, a precise process, and a satisfying result — Primescan is Seongmo Dental Clinic's commitment to making all of it possible.
Scan Data Precision
Determines Prosthetic Lifespan
Higher scan precision improves the fit at the seam (margin) where a prosthetic meets the tooth, reducing the risk of secondary decay and prosthetic detachment caused by bacteria entering through that gap.
The most common reason a crown or inlay causes problems years later isn't the strength of the material — it's the fine gap between the tooth and the prosthetic. Once bacterial biofilm settles into that gap, decay progresses beneath a prosthetic that looks perfectly fine on the outside.
Primescan's high-resolution data captures the margin line of a prepared tooth sharply. Seongmo Dental Clinic uses this data together with Q-ray diagnosis, PrimeMill milling, and T-scan occlusal analysis to manage both fit and occlusion.
The Difference Precision Makes
Fewer Corrections and Remakes
Especially Important for Implant Restorations
Also Used Directly for Orthodontic/TMJ Appliances
Precision isn't something you can see — it shows up in the result ten years later.
No Gagging —
and It's Over Fast
Intraoral scanning skips the process of biting down on material and waiting for it to set, so it's less of a burden even for patients with a strong gag reflex, children, or older patients.
A rubber impression required keeping your mouth open while the material set, and if it went wrong, you had to start over from scratch. For people with a strong gag reflex, this was sometimes a reason to put off going to the dentist.
An intraoral scan can be captured section by section, so you can take a brief break or just re-scan the part that's needed. Once scanning is done, we review your tooth condition together on a magnified 3D screen.

Dental Trauma
Comfort isn't just a courtesy — it's a condition for getting accurate data.
Where Does
Scan Data Actually Get Used?
Primescan data flows into PrimeMill chairside milling, SpeedFire sintering, in-house 3D printing, and implant surgical guide fabrication, connecting all the way to a same-day restoration in-house.
A scan isn't an exam that ends in itself — it's the starting point for all digital fabrication. Seongmo Dental Clinic connects scan → design → milling → sintering → seating in-house, finishing a restoration within a day when the case allows.
Scan data is also overlaid with 3D CT data to plan implant placement position, and is used to print surgical guides and temporary crowns with our in-house 3D printer.

Rubber Impression vs. 3D Intraoral Scan
| COMPARISON | Conventional Rubber Impression | Seongmo Dental Clinic Primescan |
|---|---|---|
| Capture Method | Bite and wait on material | Optical 3D scan |
| Gag Reflex | Easily triggered | Scanned without material |
| Error Factors | Material distortion/bubbles/transport | Digital data transferred as-is |
| Re-Capture | Start over from scratch | Re-scan only what's needed |
| Patient Explanation | Checked via plaster model | Checked via magnified 3D screen |
| What Comes Next | 1-2 weeks shipping to lab | In-house milling, same-day restorationWhen Case Criteria Are Met |
The scope of scanning and whether same-day restoration is possible depend on gum condition and case difficulty.
3D Intraoral Scanner — Glossary
- Intraoral Scanner
- A device that optically images the mouth and converts the shape of teeth and gums into 3D data.
- Impression Taking
- The process of taking an impression of tooth shape for prosthetic fabrication. Traditionally done with rubber impression material.
- Margin
- The boundary line where a prosthetic meets the tooth. Poor fit lets bacteria in, raising the risk of secondary decay.
- CAD/CAM
- CAD/CAM: A digital prosthetic fabrication method combining computer design and automated machining.
- Chairside
- A method of fabricating a prosthetic in-house at the dental clinic rather than at an outside lab.
- Surgical Guide
- A printed device, designed from scan/CT data, that guides implant placement position.
Sungshin Univ. 3D Intraoral Scanner — FAQ
Isn't a 3D intraoral scan painful or uncomfortable?
It works by moving the scanner tip along the tooth surface to capture images, requiring no anesthesia or impression material. Without the process of biting down on material and waiting, gag reflex burden is greatly reduced.
Is scanning more accurate than a rubber impression?
Primescan captures millions of data points per second, reproducing even fine contours. With no material distortion or transport error, it's advantageous for improving prosthetic margin fit. That said, if there's gum bleeding or excess saliva, we address those conditions before scanning.
If I get scanned, can I get my restoration the same day?
Seongmo Dental Clinic has an in-house system that mills scan data with PrimeMill and sinters it with SpeedFire, so same-day restoration is possible when the case qualifies. Some cases may require an additional visit.
Does it emit radiation?
The intraoral scanner is an optical camera method and doesn't use radiation. When 3D bone structure diagnosis is needed, a separate low-dose 3D CT is taken.
Can it also be used for orthodontic or TMJ appliances?
The same scan data can be used to design clear aligners, TMJ splints, denture custom trays, and more. Seongmo Dental Clinic prints some of these devices directly with our in-house 3D printer.
Is scanning billed separately?
Scanning is performed as part of the relevant treatment process — prosthetics, orthodontics, implants, etc. Treatment costs vary by material and case, so we advise after diagnosis.
