All-on-4 vs All-on-6 vs All-on-8: Which Is Right for You?
Specialist Prosthodontist · Taki Dent, Antalya
All-on-4, All-on-6 and All-on-8 all replace a full arch of teeth on a fixed bridge — the number simply refers to how many implants carry it. All-on-4 (four implants) suits most patients and needs the least bone; All-on-6 (six) adds load distribution for dense bone and heavy bites; All-on-8 (eight) is reserved for large, high-force arches with excellent bone, usually the upper jaw. More implants is not automatically better: placement quality decides longevity, and four well-placed implants outperform eight rushed ones. At Taki Dent in Antalya all three are planned on a CT scan, not sold on price.
What is the difference between All-on-4, All-on-6 and All-on-8?
The names describe a single idea executed at three scales: a full arch of fixed teeth supported by titanium implants. All-on-4 uses four implants — typically two upright at the front and two angled at the back to avoid the sinus and grab the most bone. All-on-6 adds two more implants, giving six points of support and reducing the cantilever at the rear. All-on-8 spreads the load across eight implants, putting an implant under almost every functional tooth position.
The progression is about load distribution and redundancy, not a different procedure. Each step up means more bone is needed, more surgical time, and a higher cost — which is exactly why the count should be matched to your anatomy rather than chosen for its own sake.
| All-on-4 | All-on-6 | All-on-8 | |
|---|---|---|---|
| Implants per arch | 4 | 6 | 8 |
| Bone needed | Least | Moderate | Most |
| Best for | Most patients | Dense bone / heavy bite | Large high-force arches |
| Relative cost (Turkey) | Lowest | Mid | Highest |
| Teeth in a day | Usually | Usually | Often |
Is more implants always better?
No — and this is the single most important point. Eight implants placed into bone that cannot properly support them is worse than four implants placed expertly where the bone is strong. The All-on-4 protocol has more than fifteen years of published follow-up showing four implants reliably carry a full arch for decades.
Adding implants buys two things: a margin of safety if one fails, and better force handling for heavy bites or long arches. If you do not need those things, you are paying for biology you will not use. A skilled surgeon doing All-on-4 will out-perform a rushed clinic doing All-on-8 every time.
Who is each option best for?
All-on-4 is the default for most patients, especially those with moderate bone loss who want fixed teeth in a day at the lowest cost. All-on-6 is the upgrade for patients with good bone, a heavy or grinding bite, or a longer arch who want extra resilience. All-on-8 is a niche choice — generally a large upper jaw with excellent bone density and very high bite forces, where the extra fixtures genuinely earn their place.

Frequently asked questions
Is All-on-8 worth the extra cost?
Only if your anatomy calls for it. For a large upper arch with strong bone and a very heavy bite, the extra implants add resilience. For an average case it is over-engineering — the money is better spent on a zirconia bridge and a specialist clinic.
Can I upgrade from All-on-4 to All-on-6 later?
Not easily once the bridge is made. The number of implants is decided before surgery based on your CT scan, so it is important to choose correctly the first time with a specialist who explains the trade-offs.
Which option does Taki Dent recommend most?
For most UK patients, All-on-4 or All-on-6 depending on the CT scan. All-on-8 is reserved for the minority of cases that truly need it. The recommendation is always based on your anatomy, never on selling more implants.
