The time we used to wait on a lab's schedule just to fit one device.
Now we print it in-house and
fit it right away.
Seongmo Dental Clinic operates an in-house 3D printer. We design temporary crowns, TMJ splints, denture custom trays, and implant surgical guides on computer from Primescan data and print them ourselves, cutting the delays and errors that used to come from shipping to an outside dental lab.

We turn scan data into a physical object, on the spot. Less waiting time means less room for error to creep in.
Sungshin Univ. dental 3D printer —
what does it actually make?
Seongmo Dental Clinic's in-house 3D printer directly prints temporary crowns, TMJ splints, denture custom trays, and implant surgical guides that are designed based on scan data.
Based on precision data from a 3D scanner, we design and produce surgical guides, temporary crowns, TMJ splints, and custom trays in-house on computer. This eliminates the delays and errors that came from outsourcing to a dental lab, and is the core technology behind a more precise, comfortable treatment process for patients.
The advantage of in-house production isn't just speed. Adjustments made during fitting can be fed straight back into the design and reprinted, making the refinement process far shorter.

Temporary Crowns —
how precisely do they need to fit?
A temporary crown maintains tooth shape, gum contour, and occlusion while you wait for the final restoration, so a poor fit can cause gum swelling or throw off the final prosthetic.
Treating a temporary crown as something you "just wear briefly" is a mistake that shows up at the final restoration stage. If the gum doesn't settle or the neighboring teeth shift even slightly, the prosthetic won't fit as planned.
Seongmo Dental Clinic prints temporary crowns designed from scan data in-house, keeping the shape precise. In cases where same-day PrimeMill restorations are possible, we sometimes skip the temporary-crown stage entirely.

A temporary crown's precision sets the starting line for the final restoration.
TMJ Devices —
why does precision matter?
A TMJ device eases the burden on muscles and joints by adjusting lower-jaw position and occlusal contact, so its thickness and contact surface need to match the design exactly for it to work.
Teeth grinding, clenching, and TMJ pain are problems tangled up with occlusion, muscles, and habits. Since the device's role is to redistribute that force, even a slightly off contact point changes the result.
Seongmo Dental Clinic prints splints and ARS devices in-house, then checks and adjusts contact position and timing with T-scan digital occlusal analysis. When needed, we also manage muscle load with i-JECT B precision Botox injections.

A device isn't just made for you — it's a treatment that gets fitted, over time.
Implant Surgical Guides —
what difference do they make?
By overlaying 3D CT and scan data to simulate surgery on computer, then printing a guide that follows that plan to direct placement position, angle, and depth, we can reduce the risk of nerve/vessel damage and shorten surgery time.
An implant is placed inside bone where it can't be seen. It has to find a spot with enough bone while avoiding nerves, blood vessels, and neighboring tooth roots — guided surgery is what makes that judgment call based on data instead of guesswork.
Seongmo Dental Clinic builds the plan by registering HDX Dentri 3D CT and Primescan data together, then prints the guide with our in-house 3D printer. We add ACTILINK plasma surface activation and T-scan occlusal adjustment on top, managing stability even after surgery.

Outside Lab Fabrication vs. In-House 3D Printing
| COMPARISON | Outsourced to a Lab | Seongmo Dental Clinic In-House Printing |
|---|---|---|
| PRODUCTION SITE | Outside Lab | In-house 3D printer |
| Time Required | Waiting on shipping/scheduling | Same day to short turnaround |
| Revisions | Re-order and re-ship | Redesign and reprint |
| Error Factors | Model duplication/transport steps | Uses scan data directly |
| SURGICAL GUIDES | Waiting on outside production | Printed immediately after planning |
| Scope | Separate order per device | Temp crowns/splints/trays/guides, all in-house |
The types of devices that can be printed and whether they apply depend on the case and material characteristics.
Dental 3D Printing — Glossary
- TEMPORARY CROWNS
- A temporary restoration used to maintain tooth shape, function, and gum condition before the final restoration.
- Splint
- An occlusal stabilization device worn to reduce the burden of teeth grinding and TMJ strain.
- ARS
- Anterior Repositioning Splint (ARS): guides the lower jaw forward to regulate joint load.
- Custom Tray
- A precision impression tray custom-made to the patient's gum shape, improving denture fit.
- SURGICAL GUIDES
- A printed device designed from CT/scan data that guides implant placement position.
- Navigation-Guided Surgery
- A surgical method that reproduces planned coordinates via a guide during placement.
Sungshin Univ. In-House 3D Printing — FAQ
Is a device made with a 3D printer as precise as one made by a dental lab?
Dental 3D printing uses scan data directly, reducing the errors that arise from model duplication and transport. Seongmo Dental Clinic checks fit and occlusion in the mouth after printing and adjusts as needed.
Can I get a temporary crown the same day?
Once scanning and design are complete, we print it in-house, so same-day fabrication is possible in many cases. That said, the schedule can vary depending on the number of teeth and gum condition.
Is the final restoration also made with the 3D printer?
Final ceramic/zirconia restorations are made by PrimeMill milling and SpeedFire sintering. The 3D printer is mainly used for temporary crowns, devices, guides, and trays.
How long do I need to wear a TMJ device?
It varies by symptom and cause; wear time and duration are adjusted based on progress, referencing T-scan occlusal analysis results as well.
Is an implant guide used in every case?
It's decided based on bone condition, the number of implants, and distance from risk structures. In cases that need a guide, we print it in-house after 3D CT planning.
How much does it cost?
It depends on the type of device, material, and case difficulty. Please refer to the Non-Covered Fee Guide page for uninsured items; exact costs are provided after diagnosis.
