All-on-4
A fixed alternative to a removable denture for a jaw with no remaining useful teeth — surgery first, final bridge months later.
What this treatment involves
All-on-4 replaces a whole upper or lower arch with a fixed bridge carried on four implants rather than one implant per tooth.
The two implants at the back are placed at an angle. That is the central idea: tilting them lets a longer implant engage bone that is still dense, which often avoids the bone grafting or sinus lift that vertical implants in the same jaw would require.
Where the implants are stable enough at placement, a fixed temporary bridge is fitted the same day or the next. This is what "teeth in a day" refers to — the temporary, not the finished result.
Who may be suitable
It is considered for people who have lost, or are about to lose, all the teeth in a jaw, and for those struggling with a removable denture that moves or rubs.
Enough bone must remain in the front of the jaw to hold four implants securely. Uncontrolled diabetes, smoking and untreated gum disease all raise the risk of failure. Some jaws need more than four implants for a safe result, and some need bone grafting first — which is why the assessment includes a CT scan rather than a photograph.
Whether this is appropriate for you can only be decided by a clinician after examining you and reviewing that scan.
Why patients choose it
The bridge is fixed. It does not come out, does not need adhesive, and does not move while eating or speaking — the specific complaints that lead most people to ask about this.
Because the angled implants often reach usable bone, treatment is frequently possible without grafting, which shortens the overall timeline and reduces the number of procedures. Chewing function is closer to natural teeth than any removable denture achieves.
How treatment works
Assessment and CT scan
Trip 1, day 1
A cone-beam CT scan shows bone volume and density and the position of the nerve and sinus. Treatment is planned from this, not from photographs.
Any remaining teeth removed
Day 2
Teeth that cannot be saved are extracted, usually in the same appointment as implant placement.
Implant placement
Day 2, 2–3 hours
Four implants are placed under local anaesthetic, with sedation available. The two posterior implants are angled to engage denser bone.
Fixed temporary bridge
Day 2–3
Where the implants are stable enough, a fixed temporary bridge is fitted within 24–48 hours. You leave with fixed teeth.
Healing at home
3–6 months
The implants integrate with the bone. A soft diet is required throughout. Your coordinator stays in contact.
Final bridge
Trip 2, 4–5 days
A second, shorter trip for impressions, try-in and fitting of the definitive bridge.
What happens in Istanbul
Full-arch treatment usually means two trips. The first covers surgery and a fixed temporary bridge, and lasts around five to seven days. You then return home to heal for three to six months before a second, shorter trip for the final bridge. Your coordinator confirms both sets of dates, transfers and accommodation in writing before you travel.
Recovery
Swelling and bruising of the face and lips are expected for several days and usually peak around day three. Discomfort is managed with prescribed medication.
A soft diet is required for the whole healing period — typically three to six months — because the temporary bridge is not built to take full biting force and the implants must not be loaded heavily while integrating. This is the part patients most often underestimate.
The final bridge is fitted after the implants have integrated and the gum contour has settled.
Risks and considerations
This is oral surgery under anaesthetic, and carries the risks that implies: infection, bleeding, and reaction to anaesthesia.
Implants can fail to integrate. With only four supporting a whole arch, losing one is more consequential than losing one of eight — it can mean the bridge cannot be supported until the site heals and a further implant is placed, which adds months.
Lower-jaw surgery carries a risk of injury to the nerve supplying the lip and chin, which can cause numbness or altered sensation, occasionally permanent. Upper-jaw surgery near the sinus carries a risk of sinus complications.
The temporary bridge can fracture if the soft-diet instructions are not followed. Long-term success depends on cleaning around the implants daily and attending maintenance appointments — peri-implantitis, an inflammatory condition around implants, can cause bone loss and eventual failure years later.
This information is general and educational. Whether a procedure is appropriate for you can only be determined by a qualified medical professional after an individual assessment, including your medical history and an examination.
Common questions
Do I really get teeth in one day?
You get a fixed *temporary* bridge, usually within 24–48 hours of surgery — so you do not leave without teeth. The final bridge comes three to six months later, once the implants have integrated. Any clinic describing the same-day bridge as the finished result is being misleading.
How long do I have to eat soft food?
Usually three to six months — the whole time the implants are integrating. This is the part most people underestimate, and it is not optional: biting hard food on a temporary bridge can fracture it or disturb an implant that has not yet integrated.
Why four implants and not more?
Four is the minimum that can safely carry a full arch when the bone allows it, and using fewer implants means less surgery and often no grafting. But it is not right for every jaw — some need six or more for a safe, durable result. The CT scan decides that, not a package name.
