All-on-4 vs All-on-6: Pros and Cons Side by Side
Specialist Prosthodontist · Taki Dent, Antalya
All-on-4 pros: lower cost, less bone needed, usually no grafting, faster surgery, proven 15+ year track record — cons: less redundancy if one implant fails, a small rear cantilever, less ideal for very heavy bites. All-on-6 pros: better load distribution, more redundancy (lose one, five remain), stronger for grinders and long arches — cons: higher cost, needs more bone, occasionally requires grafting, slightly longer surgery. Neither is universally better: All-on-4 suits most patients, All-on-6 is the upgrade for dense bone and heavy bites. The right pick comes from your CT scan. Taki Dent offers both at fixed Turkey prices.
What are the pros and cons of All-on-4?
All-on-4's strengths are practical and well-proven. It costs less, needs the least bone, usually avoids grafting thanks to its angled rear implants, involves shorter surgery, and is backed by more than fifteen years of clinical data. For the majority of patients it delivers a fixed, natural-feeling arch in a day at the lowest price.
Its trade-offs are modest: with only four implants there is less redundancy if one is lost, the bridge has a small cantilever at the very back, and for extremely heavy bites it offers less mechanical margin than six implants would.
| All-on-4 | All-on-6 | |
|---|---|---|
| Cost | Lower ✓ | Higher |
| Bone needed | Less ✓ | More |
| Grafting | Usually none ✓ | Sometimes |
| Redundancy | Lower | Higher ✓ |
| Heavy bites | Good | Stronger ✓ |
| Track record | 15+ years ✓ | Strong |
What are the pros and cons of All-on-6?
All-on-6's advantages centre on resilience. Six implants distribute bite force more evenly, reduce the rear cantilever, and provide genuine redundancy — lose one implant and five still support the arch. For patients with dense bone, a heavy or grinding bite, or a long arch, that extra robustness is a real benefit and can lower the chance of a mid-life mechanical complication.
The costs are equally clear: it is more expensive, requires more bone, occasionally needs a graft or sinus lift in the upper jaw, and takes a little longer in surgery.
So which set of trade-offs is right for you?
There is no universal winner — that is the honest conclusion. If you have moderate bone, a normal bite and a budget to respect, All-on-4's pros outweigh its cons comfortably. If you have dense bone, a heavy or grinding bite, a long arch or simply want maximum redundancy, All-on-6's extra strength justifies its higher cost. The decision is individual and rests on your CT scan and bite assessment, which is why a specialist opinion — not a price list — is the right way to weigh these trade-offs.

Frequently asked questions
What is the main downside of All-on-4?
Less redundancy if an implant is lost and a small rear cantilever. For most patients with a normal bite these are minor, and All-on-4's lower cost and proven record outweigh them.
What is the main downside of All-on-6?
Higher cost, more bone required and occasional grafting. The benefit — better load distribution and redundancy — matters most for heavy bites and long arches.
Which has the better pros-and-cons balance?
It depends on you. All-on-4 wins for most moderate cases; All-on-6 wins for dense bone, heavy bites and those wanting maximum redundancy. A CT scan decides.
