The full-arch decision
All-on-4 and its cousins: what the names mean
A plain-English decoder for the branded-procedure alphabet soup — and what actually differs between them.
The bottom line
All-on-4, All-on-6, Teeth-in-a-Day, and the trademarked names are all variations on one idea: a full arch of teeth on a handful of implants. The main real difference is how many implants and whose branded system it is.
Listen to this lesson
It’s mostly the same idea wearing different hats
You’ll hear a dozen names thrown around, and it can feel like each office invented its own procedure. Mostly they didn’t. “All-on-4” just means a full arch on 4 implants. “All-on-6” means the same arch on 6. That’s the headline difference right there.
A lot of the fancier names — the ones with trademark symbols — are brand names for a particular company’s implants, tools, or workflow. Useful to the dentist, marketing noise to you. Underneath, it’s the same core concept from the last lesson.
What actually differs, and when it matters
The count matters when your bone and bite call for it. Six implants spread the load over more anchors, which some surgeons prefer for the upper jaw, where bone tends to be softer. Four can be plenty in a strong lower jaw. This is a clinical call, not a loyalty program.
The other real variable is the material of the final teeth — acrylic on a metal frame, or a stronger zirconia (a tough ceramic). We’ll get into materials later. For now, know that the name of the procedure tells you less than the number of implants and what the teeth are made of.
How to cut through it in a consult
Don’t get tangled in trademarks. Ask three plain questions: how many implants, what are the final teeth made of, and why is that right for me. A good specialist will answer without a sales sheet.
If two offices quote you different “systems,” that alone doesn’t make one better. Compare the actual plan — implant count, materials, timeline, and total cost — not the branding. The best procedure is the one that fits your mouth, done by someone who does a lot of them.
Straight talk
A branded name with a trademark symbol is often just a supplier’s marketing, not a better surgery. What protects you isn’t the logo on the plan — it’s the experience of the hands doing the work.
Key things to remember
- All-on-4 vs All-on-6 is mostly about implant count.
- Trademarked names are often brand labels, not different operations.
- Implant number and tooth material matter more than the name.
- Ask: how many, made of what, and why for me.
