Why Yonsei Ona Dental
Is Different
As a Current University Hospital
Clinical Professor,
I Train Other Dentists
in Implant Procedures
Who performs your implant surgery matters most. A Yonsei University Clinical Professor who has performed complex surgeries at university hospitals operates directly.

From complex implants to final prosthetics,
a specialist who deeply studied one field takes responsibility
University Hospital-Level Collaboration
5 specialists in Prosthodontics and Integrative Dentistry collaborate for optimal surgical planning
At Yonsei Ona Dental,
We Operate Twice
Our Chief Director personally designs the optimal placement
through virtual implant surgery before the actual procedure
Fast and comfortable surgery
Minimized swelling, pain, and bone grafting
3D Oral Scanning
Precise diagnosis through oral scanning
Virtual Surgery Design
Optimal placement planning on computer

Flapless Implant &
Same-Day Placement
No gum incision means less pain and swelling,
enabling faster recovery
Immediately after flapless implant surgery
Placed through a small hole without gum incision,
resulting in minimal bleeding and swelling
- • Placement through small hole without incision
- • Minimized bleeding, pain, and swelling
- • Quick return to daily life after surgery
- • Implant placed simultaneously with extraction
- • Reduced visits and treatment duration
- • Minimized jawbone loss
The Key to Implant Longevity:
Scientific Aftercare
The main cause of implant failure is 'inflammation'.
We analyze harmful bacteria invisible to the eye
to prevent peri-implantitis at its source.
Maintenance is more important than placement
Implants are more vulnerable to inflammation than natural teeth.
NGS microbial testing identifies bacterial distribution
for personalized care that dramatically extends implant life.
Data-Based Peri-implantitis Prevention
- •Tracking peri-implantitis bacteria (P. gingivalis, etc.)
- •Proactive prevention before inflammation occurs
- •Lifetime management based on objective data
Minimal Implants, Minimal Incision,
Minimal Bone Grafting
Precise digital diagnosis ensures
only the minimum necessary procedures
Minimal Implants
Just 6 upper and 4 lower implants for secure fixation
Minimal Incision
Quick recovery with minimal incision surgery
Minimal Bone Grafting
Precise diagnosis for minimum bone grafting
DENTAL PHOBIA CARE
Afraid of the Dentist?
We Understand Your Heart
CEO Dr. Kim Yu-seong × Mental Health Specialists
Safe Dental Treatment System for Phobia Patients
Many Dentists Say This:
"Now, please relax. You'll be fine as we go along."
"Let's do sleep treatment. It costs $200-$300."
These are either too passive or too aggressive responses.
Sleep treatment is costly and can be risky
for patients with systemic diseases.
Yonsei Ona's
Step-by-Step Personalized Phobia Care
Phobia Scale Evaluation
Accurate level evaluation using empathetic questions that allow patients to answer comfortably, rather than a simple survey.
Psychological Stability Content
Psychological stability videos co-produced with mental health specialists + application of Tell-Show-Do therapy.
Medication-Assisted Treatment
Prescribing safe sedatives like Alprazolam based on evidence to alleviate anxiety.
Sleep (Sedation) Treatment
Securing safety after a systemic disease inquiry, with real-time sedation dosage adjustment using precision equipment.
Yonsei Ona's Dental Phobia Evaluation Survey
We conduct a 5-question evaluation before treatment
to precisely identify the patient's anxiety level.
Treatment methods are adjusted based on individual psychological status.
Tell-Show-Do Therapy
Anxiety doesn't disappear just with words.
We let you see, touch, and experience instruments step-by-step.

Dedicated Spaces for Comfortable Treatment
Tension-Relieving Surgery Waiting Room
A dedicated waiting space where you can compose yourself in a comfortable environment.
Dedicated Recovery Room
An independent recovery space where you can rest comfortably after sleep anesthesia.
What is Conscious Sedation?
It is a treatment method where you receive the procedure in a slightly drowsy state and won't remember most of what happened during it.
It is safe because you relax comfortably while remaining conscious, allowing you to express your state and respond during treatment.
Safety
Procedure performed while maintaining consciousness
Specialists monitor blood pressure, pulse, and oxygen saturation
Use of globally recognized medications
Significantly lower risk of sequelae/side effects as it's not general anesthesia
Reversal agents available to wake up at any time
Comfort
Sedation therapy possible with a simple injection
Only a comfortable feeling remains after the procedure
Confidence in dental treatment with only calm and stable memories
Simple procedure with low cost burden
Yonsei Ona's
Sedation System
Direct Specialist Care
Performed directly by dentists experienced in anesthesia
Systematic Pre-consultation
Thorough checks of systemic diseases, medications, respiratory health, etc.
Safe Medication Use
Medications meeting international standards, with fast recovery and fewer side effects
Continuous Monitoring
Safety management through real-time measurement of oxygen saturation, heart rate, etc.
Post-treatment Recovery Care

Yonsei Ona's Infusion Method
General Clinic (Bolus Method)
Injecting drugs all at once, making it difficult to control sedation depth and potentially causing issues.
Yonsei Ona (Infusion Method)

SCIENTIFIC AFTERCARE
What Matters More Than
Placing the Implant Is Aftercare
"We take responsibility until you can use them for life"
First dental clinic in Korea with NGS microbial testing
🧬 Global Genomics Company Macrogen Partnership
NGS Next-Generation Sequencing
Precisely analyzes 700+ microorganisms in your mouth
to identify cavity and periodontal disease-causing bacteria
Why Microbial Testing at a Dental Clinic?
The mouth is "the gateway to your body's health". Harmful oral bacteria don't just stay in your mouth—they travel through the bloodstream to affect cardiovascular disease, diabetes, dementia, and more.

Frequently Asked Questions
Do you only do full-arch implants?
No. Yonsei Ona Dental performs all implant treatments from single tooth implants to full-arch implants (All on X). We apply the same digital guided surgery system to individual implants for precise and quick treatment.
Isn't digital guided surgery more expensive?
Yonsei Ona Dental provides top-quality implant treatment at reasonable prices. The precision of digital guided surgery eliminates risk of revision surgery, making it more economical in the long run. Those 65 and older may be eligible for health insurance coverage, and we offer interest-free installments and various promotions to reduce your burden.
Can I eat right after surgery?
Yes, you can. Thanks to our same-day high-strength temporary teeth produced in our in-house lab, you can eat soft foods immediately after surgery. There's not a single day without teeth, and you can return to daily life right after surgery. Final prosthetics are crafted at the same dental lab used by Yonsei University Dental Hospital.
How is digital guided surgery different from regular surgery?
Digital guided surgery begins with 3D oral scanning for precise diagnosis, then performs virtual surgery on a computer first. This designs the optimal placement position, minimizing deviation to within 1mm and reducing incisions. The result is shorter procedure time and minimized pain, swelling, and bone grafting.
How long does implant treatment take?
It varies depending on individual oral condition, but typically takes 2-4 months. With our immediate prosthetic implant system, you can use temporary teeth right after surgery, and final prosthetics are placed after complete bone-implant integration. Exact duration will be provided after 3D CT diagnosis.
Is implant surgery painful?
You can receive treatment comfortably through conscious sedation. You'll feel almost no pain during surgery, and even after surgery, our digital guided surgery's minimal incision approach results in significantly less swelling and pain compared to traditional surgery. Prescribed pain medication is sufficient for management.
