The All-On-4 dental implant solution is designed to replace missing teeth and unstable dentures with a secure, natural-looking bridge. Eat, speak, and smile again with total confidence.
All-on-4 is a revolutionary dental restoration technique for patients who have lost all of their teeth. It was developed by Nobel Biocare (Sweden) and first introduced by Dr. Paulo Malo in 1998.
Meaning of the name: “All” refers to all teeth in one arch being supported “On 4” dental implants.
Nature of the technique: Instead of placing an individual implant for every missing tooth (which is costly and invasive), surgeons place only 4 implants per arch to act as a foundation. A fixed bridge of 12-14 teeth is then securely attached to these 4 implants.
This method is typically recommended for:
Full edentulism: People who have lost all teeth in the upper arch, lower arch, or both.
Severely damaged teeth: Patients with remaining teeth that are loose or suffering from severe periodontal disease that cannot be saved.
Jawbone resorption (Bone loss): Patients who have lost bone in the posterior (back) area and want to avoid complex bone grafting procedures required by traditional implants.
Denture wearers: Those who find traditional removable dentures uncomfortable, loose, or painful.
The uniqueness of All-on-4 lies in the specific positioning and angulation of the implants:
Implant Positioning:
2 Front Implants: Placed vertically in the anterior (front) region (usually at the position of the lateral incisors).
2 Rear Implants: Placed in the posterior (back) region and tilted at an angle of up to 45 degrees
Tilting the back implants allows the surgeon to utilize the higher-quality bone available in the front of the jaw. This avoids critical anatomical structures like the maxillary sinuses (in the upper jaw) or the mental nerve (in the lower jaw), eliminating the need for bone grafts.
Specialized connectors (abutments) are used to compensate for the implant angles, ensuring that the final bridge sits straight and provides a balanced bite.

The implants (the screws) are designed to be permanent and can last 20 years to a lifetime with proper care. The prosthetic bridge (the teeth) undergoes wear and tear and may need replacement or repair every 10–15 years.
All-on-4 uses 4 implants, while All-on-6 uses 6. All-on-6 provides more stability and distribution of pressure, but it requires more bone volume. All-on-4 is often preferred for patients with significant bone loss.
Unlike dentures, All-on-4 is fixed (doesn’t slip), allows you to eat almost any food, prevents bone loss, and does not require messy adhesives or daily removal.
For the first 3–4 months, you must stick to a soft food diet (pasta, fish, eggs, cooked vegetables). This is the “osseointegration” period where the implants fuse with your bone. Once the final permanent bridge is attached, you can eat steak, apples, and crunchy foods.
