What Is an All on 4 Bridge? (Complete Explanation)
An All on 4 bridge is a full-arch dental restoration supported by just four strategically placed implants. Designed for patients who have lost most or all of their teeth, this treatment replaces an entire row with a fixed, natural-looking prosthetic bridge. It’s important to understand that the All on 4 bridge offers improved stability, chewing power, and long-term oral health compared to traditional dentures.
This system is especially popular among adults seeking a permanent, aesthetic, and functional alternative to removable dentures.
How the All on 4 Bridge Works
The procedure is based on two core principles:
1. Strategic Implant Placement
- Two implants are placed vertically in the front of the jaw.
- Two rear implants are placed at an angle to maximize bone support.
- This eliminates the need for bone grafting in most cases.
2. Immediate Function
Many patients receive a temporary fixed bridge on the same day — often called Teeth-in-a-Day.
This approach offers:
- Immediate cosmetic improvement
- Ability to eat soft foods within 24 hours
- Faster psychological and functional recovery
Benefits of the All on 4 Bridge
1. Permanent Tooth Replacement
The All on 4 bridge acts like natural teeth. Unlike dentures, it doesn’t move or slip.
2. Avoids Bone Grafting
Angled implant placement uses available bone, even in patients with bone loss.
3. Faster Results
Patients can often leave with a full new smile on the same day of surgery.
4. Natural Look & Feel
The bridge is custom-designed to match the shape, color, and contour of natural teeth.
5. High Success Rate
Studies show All on 4 implants have a 95–98% success rate when properly maintained.
6. Improves Overall Health
Replacing missing teeth reduces:
- Gum inflammation
- Oral infection risk
- Bite issues and TMJ discomfort

The All on 4 Bridge Procedure: Step-by-Step
1. Consultation & 3D Imaging
Your dentist evaluates bone levels, oral health, and treatment goals using CBCT scans.
2. Treatment Planning
A customized digital plan outlines:

- Bite alignment
- Aesthetic design of the new smile
3. Implant Placement
The 4 implants are surgically inserted under local anesthesia or sedation.
4. Same-Day Temporary Bridge
A temporary bridge is attached so patients never go toothless.
5. Healing Phase (3–6 months)
Implants fuse with the bone (osseointegration).
6. Final All on 4 Bridge Placement
A durable, zirconia or acrylic hybrid bridge is placed for long-term function.
