How to Choose Between All-on-4 and All-on-6 for Your Case
Specialist Prosthodontist · Taki Dent, Antalya
Four factors decide between All-on-4 and All-on-6: your bone (more bone makes All-on-6 possible), your bite (heavy grinders benefit from six implants), the arch (the upper jaw and longer arches often favour six), and your budget (All-on-4 costs less). The choice should be made on a CT scan by a specialist, not on a price list. As a rule of thumb, most patients with moderate bone and a normal bite do excellently on All-on-4; All-on-6 is the upgrade for dense bone, heavy bites or extra peace of mind. Taki Dent gives a free CT-based recommendation before you commit.
What four factors actually decide it?
Strip away the marketing and the decision rests on four things. Bone volume: All-on-6 needs more bone to place two extra implants, so dense, healthy bone opens that option. Bite force: heavy chewers and grinders put more load through the arch, where six implants distribute stress better. The arch itself: the upper jaw is softer and longer arches carry more leverage, both nudging toward six. Budget: All-on-4 costs less, which matters and is a legitimate factor.
No single factor decides alone — your specialist weighs them together against your CT scan.
| If you have… | Lean toward |
|---|---|
| Moderate bone, normal bite | All-on-4 |
| Dense bone, heavy/grinding bite | All-on-6 |
| Upper jaw, long arch | All-on-6 (if bone allows) |
| Tighter budget | All-on-4 |
| Want maximum redundancy | All-on-6 |
What questions should you ask your dentist?
Ask: "Based on my CT scan, do I have enough bone for All-on-6, and would it meaningfully benefit me?" Ask what implant brand and bridge material are included. Ask whether the rear implants will be angled to avoid grafting. Ask what guarantee backs the work and who handles complications. A specialist who answers these clearly — and recommends All-on-4 when it suits you rather than upselling — is the one to trust.
What are the red flags?
Be wary of any clinic that recommends All-on-6 (or All-on-8) for everyone regardless of anatomy — that is selling implants, not planning treatment. Be wary of quotes that seem too low to include a zirconia final bridge. And be wary of a plan made without a CT scan: you cannot honestly choose between four and six implants without seeing the bone. The right answer is individual, and it comes from imaging plus specialist judgement.

Frequently asked questions
Can I decide between All-on-4 and All-on-6 before a scan?
Not properly. The choice depends on your bone volume and bite, which a CT scan reveals. Any clinic deciding without imaging is guessing.
Is it a red flag if a clinic always recommends All-on-6?
Yes. Recommending six implants for every patient regardless of anatomy suggests selling rather than planning. A specialist recommends All-on-4 when it suits you.
How does Taki Dent help me choose?
Taki Dent provides a free CT-based recommendation, explaining whether your bone and bite favour four or six implants before you commit to anything.
