Let’s start by clearing up a common confusion, because there’s a lot of poorly told information out there.
Full Arch and All-on-4 are not opposites. It isn’t “one or the other.” They complement each other. Full Arch means a complete arch: giving you back all the teeth on top, on the bottom, or both, with a fixed prosthesis on implants. It’s the concept. All-on-4 is one of the ways to achieve it: the entire arch supported on exactly four implants. So every All-on-4 is a Full Arch. But a Full Arch can be built on four, five or six implants, depending on what your case needs. If you see the comparison framed as “one versus the other,” it’s worth asking to have it explained again. They are not rival techniques.
Why sometimes four and sometimes six?
It isn’t a random number or a whim of the dentist. It’s engineering. Think of a bridge: how many columns it has and where they go depends on the forces it must support. The same applies to your arch. What determines the number is how chewing forces distribute across your bone, how much bone you have and where you have it. And here’s something rarely mentioned: fewer, well-placed implants are easier to keep clean. Cleaning a four-legged table is quick. Now go clean a railing with vertical posts every five centimeters. Hygiene is what sustains the result over ten years, and a prosthesis that’s hard to clean complicates that maintenance. That’s why the number of implants is a judgment call, not a matter of “the more the better.”
Immediate loading: how it actually works
Immediate loading means you won’t be left without teeth. We work with two protocols, and both are immediate loading:
The 48 to 72 hour protocol. You leave with a fixed temporary, with all your teeth, in two or three days. It’s a temporary: it serves function and aesthetics while the bone integrates.
The 2 to 3 week protocol. Instead of a temporary, you take the final prosthesis with you right away. Two weeks for a single arch, three for both. You go home to eat with the final one in place. Which is better? It depends on your case and your availability. Neither is “the fast one and the slow one”: both are immediate loading, with different criteria. Shorter timelines than these are technically possible, and I’ve done them. But I prefer not to offer them: if any adjustment comes up along the way, the patient ends up racing the clock. And when someone has bought a round-trip ticket, that pressure doesn’t help anyone. I’d rather give you a timeline that holds.
What this resolves
- You’ve lost most of the teeth in one arch, or all of them.
- You wear a removable denture and you’re tired of it moving, of adhesives, and of not being able to eat with confidence.
- You have teeth with severely compromised support and you know they’ll be lost soon.
- You were told you don’t have enough bone for conventional implants. On that last point: the lack of posterior bone is precisely the problem these techniques solve. With strategically tilted implants we take advantage of the dense bone that remains, and grafts that would extend treatment by several months are often avoided. If you received that diagnosis years ago and haven’t consulted since, a second opinion with a CT scan is worth it.
Fixed on implants or removable denture
Removable denture Fixed Full Arch
Moves while eating yes no
Adhesives yes no
Covers the palate generally yes no
Taste and temperature reduced preserved
Bone continues resorbing stays stimulated
Removed at night yes no Removable denture Fixed Full Arch
Initial cost lower higher
Replacements over 10 years several maintenance
How much it costs
A full rehabilitation of one arch starts from $15,000,000 COP. The variation depends on the number of implants, the prosthesis material, the implant system and whether preparatory work is required. I won’t give you a closed figure without a CT scan, because without seeing your bone it would be a blind estimate.
What to ask before accepting
1. How many implants, and why that number in my case? 2. Will I leave with a fixed temporary or the final prosthesis, and in how many days? 3. Will the prosthesis be screw-retained? 4. What implant brand and components? 5. How will I clean it at home? 6. How often are the follow-ups?
Closing
A well-planned Full Arch isn’t just aesthetics. It’s chewing properly again, halting bone loss and recovering the support of your face. I’ve spent 38 years in implantology and today we do this fully digitally: surgical guides generated by software, prostheses designed by computer, zero guesswork. It isn’t the future; it’s what my patients receive today. If you’re evaluating a full rehabilitation, come in with time for a proper assessment. I’ll show you your case on screen and explain what can and can’t be done.
Frequently asked questions
Are Full Arch and All-on-4 the same thing? Full Arch is the concept of a complete fixed arch. All-on-4 is doing it on four implants. All-on-4 is a type of Full Arch. Will I be without teeth at any point? No. You leave with fixed teeth in 48–72 hours, or with the final ones in 2–3 weeks depending on the protocol. Can it be done if I have no bone? In most cases yes, with tilted implants that use the available bone. It’s determined with a CT scan. How long does it last? Implants can last decades. The prosthesis requires maintenance and eventual replacement, which is why it’s best that it be screw-retained. Can I eat normally? After the adaptation period, yes. That’s the main difference compared to a removable denture.
