Seoul Lab Dental Clinic offers All-on-4 full-arch implant solutions for patients seeking a fixed, stable, and esthetic new smile. Serving both domestic and international clients in northern Seoul, our team combines advanced planning, premium implant systems, and patient-focused care to deliver durable, natural-looking outcomes.

What Is the All-on-4 Implant System?

All-on-4 refers to a treatment concept in which a full arch of replacement teeth is supported by only four strategically placed dental implants. Two implants are placed vertically in the front of the jaw, and two are placed at an angle in the posterior region. This technique reduces the need for bone grafting in many cases and allows for immediate function in many patients.

When Is All-on-4 Appropriate?

You may consider All-on-4 when:

• You have lost many or all of your teeth in one or both jaws
• You want a fixed alternative instead of removable dentures
• You have some bone loss but not enough for standard full-arch implants
• You seek a quicker route to restoration with fewer implants
• You desire improved chewing, speaking ability, and aesthetics with a stable prosthesis

Advantages of All-on-4

• Fewer implants needed (just four per arch)
• Often avoids or minimizes bone grafting, thanks to angled implant placement
• Immediate load / provisional prosthesis often placed on the same day or shortly after surgery
• Fixed, non-removable solution unlike conventional dentures
• Improved function and esthetics compared to removable prostheses
• Cost-effective for full-arch restoration compared to placing many individual implants

Our All-on-4 Treatment Workflow

1. Consultation & 3D Imaging
   CBCT scans and digital planning to assess bone volume, jaw anatomy, and optimal implant angulation.
2. Treatment Planning & Prosthetic Design
   Design of the full-arch prosthesis and surgical guide to position implants optimally for support and esthetics.
3. Surgical Implant Placement
   Under local anesthesia (or sedation if needed), four implants are placed — two vertical and two tilted — to maximize stability and avoid anatomical structures.
4. Provisional (Temporary) Prosthesis
   A temporary fixed arch is attached, allowing immediate function while healing occurs.
5. Healing & Osseointegration
   Over a healing period (typically 3–4 months), implants integrate with bone.
6. Final Prosthesis Placement
   Once integration is confirmed, the final prosthetic arch is anchored, with custom shaping, aesthetics, and occlusion.
7. Follow-Up & Maintenance
   Regular check-ups, cleaning, and adjustment to ensure long-term success.
