All-on-4 Dental Implants: A Full Arch on Four Implants

All-on-4 is a full-arch implant technique that replaces an entire row of teeth using just four implants. The two back implants are placed at an angle to anchor in strong bone, which is why most patients avoid bone grafting and can leave with fixed provisional teeth the same day.

How four implants can hold a whole arch

The four posts are positioned like table legs at engineered angles, spreading bite forces across the strongest parts of the jaw. Once the implants integrate with the bone, they collectively support a full bridge of 10 to 14 teeth that does not slip, click, or come out at night.

The All-on-4 timeline

• Planning: 3D imaging maps your bone and nerve positions; the case is designed digitally before anything happens in your mouth
• Placement day: failing teeth are removed, four implants placed, and a fixed provisional arch attached, typically in one visit
• Healing: implants fuse with bone over roughly 3 to 6 months while you wear the provisional teeth
• Final bridge: a custom, stronger final arch is fitted and calibrated to your bite

Who is a good All-on-4 candidate

Most adults with a failing arch qualify, even after years of dental problems or long-term denture wear. The technique was designed for reduced bone volume, so past bone loss rarely rules it out. Smoking and uncontrolled diabetes need managing first; 3D imaging gives the real answer.

All-on-4 vs All-on-6

Four implants is the proven minimum; six adds redundancy and force distribution for heavier bites or softer upper-jaw bone. Neither is universally better; anatomy decides. Compare in our All-on-6 guide or start with the full All-on-X overview.

FAQ

How long do All-on-4 implants last?
The implants can last decades with good hygiene; the bridge typically serves 10 to 15 years or more before refurbishment.

Is All-on-4 better than dentures?
For most patients, dramatically: fixed teeth restore up to near-natural chewing force, protect the jawbone from shrinking, and never slip.

What if I still have some healthy teeth?
Then All-on-4 may be the wrong tool. Healthy teeth are worth saving; options like veneers or crowns come first.
