All-on-4 vs All-on-6 Dental Implants Explained | DNS Dental Care, Delhi

If you have lost most or all of the teeth in one jaw, you have probably come across two terms that sound almost identical: All-on-4 and All-on-6. Both are full-arch implant treatments. Both replace an entire set of teeth with a fixed bridge that does not come out at night. And both can, in many cases, give you back a full set of teeth within a day or two of surgery.

So what actually separates them, and how do you know which one is right for you? Here is a plain-language guide from the implant team at DNS Dental Care in Lajpat Nagar, Delhi.

What "All-on-4" and "All-on-6" Really Mean

The number refers to how many implants support the bridge in that jaw, not how many teeth you get. In both cases you receive a complete arch of 12 to 14 teeth.

In an All-on-4, four titanium implants carry the arch. Two sit upright at the front of the jaw, where bone is usually thickest and best preserved. The back two are deliberately tilted, often at around 30 to 45 degrees. That tilt is the clever part: it lets the implant grip more bone, and it steers clear of the sinus above and the nerve canal below.

In an All-on-6, six implants share the load, usually spread from front to back across the arch. The extra pair means the biting force is distributed over more points instead of four.

The Main Practical Difference: Your Bone

The single biggest factor is how much jawbone you have left. When teeth are missing for years, the bone that used to hold them slowly shrinks away.

All-on-4 was designed for exactly that problem. Because the rear implants are angled to reach available bone, many patients who were previously told "you don't have enough bone for implants" can be treated without a separate bone grafting or sinus lift procedure. That means one surgery instead of two, and months saved.

All-on-6 generally asks for a bit more bone volume, but rewards you with greater support. It is often preferred in the upper jaw, where bone tends to be softer, and for patients with a powerful bite or a history of grinding. There is also a margin-of-safety argument: if one implant were ever to fail, five remaining implants share the strain more comfortably than three would.

Timeline: Teeth the Same Day, Final Bridge Later

Both treatments follow a similar path. Surgery usually takes two to four hours per arch. A temporary fixed bridge is fitted immediately or within a day or two, so you do not go home without teeth.

Over the next three to six months the implants fuse with the bone, a process called osseointegration. You stay on softer foods during the early part of this period. Once healing is confirmed, fresh impressions are taken and your permanent bridge, in high-strength zirconia or a reinforced acrylic, is fitted. Long-term studies of both protocols report survival rates in the mid-nineties percent over ten years, provided case selection, surgical technique and follow-up care are all sound.

Which One Will Your Dentist Recommend?

Honestly, this is not a decision you can make from a website, and you should be wary of any clinic that quotes you a plan before scanning you. At DNS Dental Care we start with a 3D cone beam CT scan, which shows bone height, width and density, and the exact position of your sinuses and nerves. That scan, plus your gum health, your bite and your general health, decides the answer.

A few things influence candidacy for either option. Uncontrolled diabetes and active gum disease need to be brought under control first, because both slow healing. Smoking and tobacco use meaningfully raise the risk of implant failure, so cutting down or quitting before surgery genuinely changes your odds. There is no upper age limit; patients in their seventies and eighties do very well.

Living With a Full-Arch Bridge

Fixed teeth are not maintenance-free teeth. Brush the bridge twice daily with a soft brush, clean underneath and around the implant connections with a water flosser or interdental brush, and come in for a professional clean every three to six months. The enemy is peri-implantitis, gum inflammation around implants, and it is almost entirely preventable with good hygiene. If you grind your teeth, a night guard protects your investment.
