All-on-4 Dental Implants (Malo Bridge)
All-on-4 replaces a full arch of missing or failing teeth using just four dental implants — two placed vertically at the front and two angled at the back to maximize contact with available bone. The angled placement often avoids bone grafting and allows a fixed set of teeth, with permanent prosthetics typically completed after 3-6 months of healing.

How All-on-4 works
Instead of one implant per tooth, All-on-4 supports an entire arch on just four implants. Two are placed vertically at the front of the jaw, and two are angled at the back — a design that uses the densest available bone and avoids the sinus and nerves. That angulation is why All-on-4 often avoids bone grafting.
Four is the protocol, not a rule. All-on-4 is Nobel Biocare’s trademarked four-implant concept, and four works well in a great many arches. In practice we place four to six depending on what your bone supports — more anchor points spread the chewing load and leave redundancy if an implant is ever lost, which matters for heavy bite forces and bruxism. Placing six where there is only bone for four is worse, not more thorough, so your CBCT decides it. A bridge on five or six is strictly All-on-X rather than All-on-4; you will see both terms used.
A fixed bridge of teeth attaches to those implants. Most patients leave surgery day with a fixed temporary set of teeth, and the permanent prosthesis is placed after 3-6 months of healing. With our on-site laboratory, that can mean you leave with fixed teeth in 48 hours.
All-on-4 vs. traditional implants
| Implants per arch | 4–6 |
| Bone graft usually needed? | Often no |
| Teeth on surgery day? | Usually yes |
| Removable? | No — fixed |
| Time to final teeth | 3-6 months |
What All-on-4 costs at Innate Dental Solutions
A fixed full arch starts at $13,000 per arch, and the premium All-on-4 Malo Bridge is $17,500 per arch — all-inclusive of surgery, sedation, and the final teeth. The Malo Bridge figure is our price through December 31, 2026; it rises to $25,000 per arch on January 1, 2027 — terms. Financing brings the fixed arch to roughly $172/month and the Malo Bridge to roughly $265/month.
Deciding what the arch itself should be made of? Compare the titanium-bar Malo bridge against a monolithic zirconia arch — weight, repairability, bruxism and cost, side by side.
Severe upper-jaw bone loss? Zygomatic implants can support a fixed arch when standard All-on-4 isn't possible. A 3D scan at your free consult confirms the right approach.
