DentalAll-on-6 & All-on-8
All-on-6 and All-on-8 restore a full arch on six or eight implants, spreading chewing forces over more anchor points β useful for denser bone, heavier bites and full zirconia bridges. Here is how they work and cost.
Last reviewed: 20 July 2026
What All-on-6 and All-on-8 are
Like All-on-4, these are full-arch, fixed solutions where a bridge of 10β14 teeth is screwed onto implants. The difference is the number of implants: six (All-on-6) or eight (All-on-8). More implants share the chewing forces across more points, which can improve support for a heavy, rigid zirconia bridge, help in cases of strong clenching, and provide redundancy if one implant were ever to fail. The trade-off is more implants, potentially more surgery, and a higher price.
All-on-8 is essentially the same principle taken further, used mainly for the upper jaw or for large, full zirconia bridges where maximum distributed support is wanted. The choice between four, six and eight is a clinical judgement based on bone volume and density, bite forces, the arch (upper bone is softer than lower), and the final bridge material.
Who it suits β and who it may not
All-on-6/8 may be preferred when you: have enough bone to place six or eight implants, want a full zirconia bridge, clench or grind heavily, or are restoring the upper jaw where bone is softer and extra support helps. It may not be the route if you: have limited bone that only supports four implants (All-on-4 or grafting), or a tighter budget where the extra implants are hard to justify. As always, uncontrolled diabetes, heavy smoking and active gum disease are managed first, and a CBCT scan is decisive.
Step by step
- 1. CBCT planning Positions for six or eight implants, avoiding sinus and nerve.
- 2. Extractions Any remaining unrestorable teeth removed.
- 3. Implant placement Six or eight implants placed, with multi-unit abutments as needed.
- 4. Temporary bridge Often a fixed temporary the same day where stability allows.
- 5. Healing Roughly 3β6 months of osseointegration.
- 6. Final bridge A definitive bridge β frequently monolithic zirconia β fitted after healing.
Materials and systems
The implants are titanium; the extra support of six or eight implants pairs naturally with a strong milled zirconia bridge, though acrylic-titanium bridges are also used. The same implant systems apply (Straumann, Nobel Biocare, Osstem, MegaGen and others). Precision multi-unit abutments and an accurate, passive framework are even more important with more implants, because any misfit is shared across the bridge.
Healing, risks and timeline
Timeline and healing mirror All-on-4 β a temporary bridge, a soft-diet healing period, then the final bridge, usually across two trips if treated abroad. Risks are the same family: infection, implant non-integration, nerve or sinus involvement, bite and speech adaptation, and long-term maintenance. With more implants there is more surgery but also more redundancy.
Choosing between four, six and eight implants
There is no single right number β it is a balance of biology, mechanics and budget. Denser lower-jaw bone often achieves excellent stability with four implants, while the softer upper jaw can benefit from six or eight to spread load. Heavy clenchers and people who want a rigid, wear-resistant zirconia bridge lean towards more implants, because a solid bridge transmits force with little cushioning. Redundancy is a genuine advantage of six or eight: if one implant were ever lost, the remaining implants may still support the bridge, whereas losing one of four is more consequential. Against that, more implants means more surgery, more cost, and β with more anchor points β an even greater need for an accurate, passive framework. A CBCT scan turns this from guesswork into a measured decision.
Aftercare and long-term maintenance
A full-arch bridge is cleaned underneath, where it meets the gum, with superfloss, floss threaders or a water flosser; skipping this invites peri-implantitis around several implants at once. Plan on regular professional cleanings, and understand that the bridge itself is a serviceable component β screws are checked and re-tightened, acrylic teeth can be repaired or replaced, and a zirconia bridge is more wear-resistant but not indestructible. Keeping a record of your exact implant system helps a dentist at home service the work.
Typical approach in Turkey and indicative price
Turkish clinics commonly present All-on-6 (and sometimes All-on-8) as an upgrade from All-on-4, frequently bundled with a zirconia final bridge. Because the number of implants and the bridge material both change, compare quotes carefully β an "All-on-6 zirconia" package is not comparable to an "All-on-4 acrylic" one.
Indicative bands only (GBP; rates fluctuate). Verify with the clinic β implant count and final bridge material drive the price. See the implant cost guide.
Frequently asked questions
Is All-on-6 better than All-on-4?
Not universally β it depends on your bone and bite. All-on-6 spreads load over more implants, which can support a heavier zirconia bridge and add redundancy, but it needs more bone and costs more. All-on-4 is often enough and more economical. A CBCT-based assessment decides which is appropriate for you.
When is All-on-8 used?
All-on-8 is used mainly for the upper jaw or large full-zirconia bridges where maximum distributed support is wanted, and where there is enough bone for eight implants. It is less common than four or six and is a clinical judgement rather than a default upgrade.
Do more implants mean the bridge lasts longer?
More implants can better support a heavy bridge and provide backup if one fails, which may help longevity, but the biggest factors are hygiene, not smoking, bite control and regular reviews. More implants is not a substitute for maintenance.
Can I have a zirconia bridge with All-on-6?
Yes β the extra support of six implants pairs well with a strong, wear-resistant monolithic zirconia bridge, which is a common combination. Zirconia costs more than acrylic-titanium, so confirm which material the quote includes.
Does All-on-6 need bone grafting?
Sometimes. Placing six implants needs more available bone than four, so grafting or a sinus lift may be required if bone is limited β or All-on-4 or angled implants may be chosen instead. Your 3D scan determines what is realistic.
How many trips does All-on-6 take?
Usually two, like All-on-4: one for surgery and a same-day temporary bridge, and one a few months later for the final bridge. Confirm the schedule, inclusions and aftercare in writing before travelling.
