Full-arch dental implants
All-on-6 Dental Implants in Turkey
All-on-6 dental implants replace a whole upper or lower arch with a fixed bridge held by six implants. A dentist may suggest six instead of four because of your bone, your bite or the bridge design. However, more implants do not mean a better result for everyone, so your plan is confirmed only after an in-person examination and a CBCT scan.

Typical ranges only. Your plan, timeline and number of implants are confirmed only after an in-person examination and CBCT imaging.
Why six? How All-on-6 dental implants work
Your surgeon places six implants along the jaw and then screws one bridge onto them. So the bridge rests on six points of support instead of four.
Still, where each implant goes matters as much as the number. For example, a wider spread can shorten the part of the bridge behind the last implant. However, bone, bite and materials shape that decision too.
- 1
Six implants, spread out
Your dentist spreads them from the front towards the back. In one review, implants spread this way also survived better.
- 2
A shorter overhang
Also, support further back can shorten the bridge overhang. Even so, no single measurement sets a safe length.
- 3
One fixed bridge
A single bridge carries a full arch of teeth. You don't take it out yourself. Instead, your dentist removes it for check-ups and cleaning.
When All-on-6 dental implants may suit you
A dentist weighs these points after examining you. So treat them as a guide, not a checklist.
Six implants may be proposed if
Six may not be needed, or a different plan may be safer, if
All-on-6 dental implants, All-on-4 or an overdenture?
Notably, reviews found similar implant survival with four and six implants. So the choice depends on your bone, your bite and the bridge design. Alternatively, an overdenture that clips on is easier to clean.
Your journey with All-on-6 dental implants
A common pathway uses two trips to Istanbul. However, grafting or a complex bite can add stages.
- 1Online
Remote review
First, photos, an X-ray or a CBCT scan let a dentist prepare a provisional plan. So four or six is only a suggestion at this stage.
- 2Trip 1
Examination and CBCT
In person, your dentist then checks your bone along the whole arch and confirms how many implants you need.
- 3Trip 1
Placing your All-on-6 dental implants
Next, your surgeon removes any teeth that cannot be saved and places the six implants.
- 4Trip 1
Temporary bridge
Your dentist fits it soon after surgery, but only if the implants are stable enough. Otherwise, you wear a removable denture while you heal.
- 5At home
Healing
The implants fuse with the bone over several months, and longer if you had a graft. Meanwhile, you eat softer food.
- 6Trip 2
Definitive bridge
New scans and try-ins come first. Then your dentist fits the final bridge and adjusts your bite.
Living with All-on-6 dental implants
Eating
Eat soft food while the implants heal. Later, your dentist tells you when to widen your diet, although very hard food can still chip the teeth.
Cleaning
Above all, clean under the bridge every day. If plaque stays there, your gums can bleed and swell, and in time you could lose an implant.
Check-ups
After treatment, see a dentist or hygienist every 3 to 6 months. At these visits, your dentist checks the screws, the teeth and the gums around each implant.
Risks of All-on-6 dental implants
Six implants do not remove the usual risks of a full-arch bridge. In fact, a 2026 review found similar complication rates with four and six. Even so, 95.2% to 99.2% of implants survived in long-term reviews.
However, survival is not the same as being problem-free. So ask for written terms on who pays if something needs repair.
Occasionally an implant fails, often in the first months. Smoking raises this risk, so NHS advice is to stop at least six months before treatment.
Over time, bridge teeth wear and may then need replacing. In long-term reviews, veneered zirconia chipped in 15% to 35% of cases, while solid zirconia had fewer problems.
The screws that hold the bridge loosened in 5% to 15% of cases. So your dentist checks and tightens them at maintenance visits.
If plaque builds up, it can inflame the gums around implants. When the damage reaches the bone, dentists call it peri-implantitis, and reviews found it in 4% to 18% of patients.
If you grind your teeth, the extra force can overload implants and lower success. So tell your dentist before your bridge is designed.
Some bone loss around implants is common. However, in two reviews it was slightly lower with six implants than with four.
What your All-on-6 plan should answer
Ask any clinic, including us, for clear written answers before you book.
- 1Why six implants for me, and not four?
- 2Where will each implant go along my arch?
- 3Do I have enough bone, or do I need a graft or a sinus lift?
- 4Will my temporary teeth be fixed or removable?
- 5What is the final bridge made from, and why?
- 6How will I clean underneath it?
- 7What happens if one implant doesn't fuse with the bone?
- 8Which repairs are included, for how long, and who pays for travel?
All-on-6 dental implants: your questions
Not in general. Reviews found similar implant survival with four and six implants. However, some studies found slightly less bone loss or fewer technical problems with six. So your bone, bite and bridge design decide which suits you.
Dentists weigh bone, bite and bridge design differently. Also, a remote plan is only provisional. Therefore, ask each clinic to explain in writing why it chose that number.
Usually, yes, because the extra implants need bone further back. If there is too little, a graft, a sinus lift or a four-implant layout with tilted implants may be options.
Often two. On the first trip, your dentist places the implants and, if they are stable, fits a temporary bridge. After several months of healing, you return for the final bridge.
In long-term reviews, bridges survived in 89.5% to 96.8% of cases over 5 to 15 years. However, no one can promise a lifetime, and the teeth may need repair or replacement.
It can be, because a denture that clips onto implants is easier to clean. On the other hand, fixed bridges gave better chewing and stability in one review.

Are All-on-6
dental implants
right for you?
Send a recent X-ray or CBCT scan and a few photos. A dentist will then explain whether six implants, four or another option looks suitable. Your plan stays provisional until you're examined in person.
