All-on-4 is a way to replace a full set of upper or lower teeth using four implants and one fixed bridge. The four titanium posts go into the parts of the jaw where bone is usually strongest. A single bridge of teeth is fixed onto those posts. It does not come out at night. You brush it like natural teeth.
The name is literal. All of the teeth in one jaw, carried on four implants. If someone has lost most of their teeth in the upper jaw, the lower jaw, or both, this gives them back a fixed set they can bite and chew with.
We see three situations most often at Smile Dental. People who have worn a full denture for years and are tired of it moving. People who have several loose or failing teeth left in one jaw and want one clear plan instead of fixing them one by one. And people who lost teeth long ago and were told the bone had shrunk too much for regular implants.
That last group matters. All-on-4 is designed to work with the bone you still have. The back implants are angled to catch solid bone, which often means you can avoid separate bone grafting. Dr. Rajesh confirms this with a 3D scan before anything is planned.
The full path runs across a few months, with most of that time spent letting bone heal around the implants. Here is what each stage looks like.
Dr. Rajesh examines your jaw, gums, and bite, and takes a 3D scan to map bone volume and the position of nerves and sinuses. You leave with a written plan and the full cost before any treatment is booked.
On the day of surgery, any teeth that cannot be saved are removed, four implants are placed under local anaesthesia, and a fixed temporary bridge is attached the same day in most cases. You go home with teeth, not a gap.
Over the next few months the bone fuses with the implants. You eat softer food during this window and keep the area clean. Reviews are scheduled to check that healing is on track.
Once the implants are stable, we take a digital scan and fit your permanent bridge. This is stronger and made to match the look you want. From here you care for it with brushing and regular cleanings.
These are different levels of the same idea, replacing a full arch on implants. Which one fits depends on your bone and how you chew.
All-on-4 uses four implants to hold a fixed bridge. All-on-6 uses six, which spreads the load and is often chosen for people who chew hard food or want extra stability. An implant-retained denture uses two to four implants to hold a denture that snaps on firmly but still comes out for cleaning. It costs less and suits people who want more grip than a normal denture without a full fixed bridge.
None of these is automatically the right one. Dr. Rajesh talks through your scan and your daily habits, and you decide together.
Pricing is the same at both branches. These are real ranges, not teasers.
The range comes from the implant brand and the material of the final bridge. If any extra work is needed, it is quoted during the consultation, not added later. For context, the same full-arch work runs far higher in the US, UK, and Australia, which is why many families abroad plan it for an India visit.
From the first visit to the final bridge is usually a few months, because bone healing sets the pace and cannot be safely rushed. For NRI patients, we split it across two India trips. Trip one covers the assessment, the implant placement, and the fixed temporary bridge, so you fly home with teeth already in place. Trip two, a few months later, is for the permanent bridge.
The step that saves the most trouble is the pre-arrival plan. WhatsApp your recent X-ray or scan before you book flights. Dr. Rajesh reviews it and sends back a realistic timeline and cost, so your trip is planned around what can actually be finished.
Dr. Rajesh Kumar leads these cases. He holds an MDS in Orthodontics and a Fellowship in Implantology from Germany, and has been placing implants since 1997. Full-arch work rewards that kind of long experience, because the planning of angles and bite is what makes the result comfortable for years.
Two other things come up often in patient feedback. The full cost is shown before treatment starts, including the final bridge, so there is no surprise bill halfway through. And the plan is explained with your own scan in front of you, so the decision stays yours.

Implants are the best way to replace a missing tooth, and not right for everyone. Honest candidacy, why they can still be lost, and why one quote is far higher than another.
