The short version
- A full arch is carried on four to six implants, not one per tooth.
- Angled placement often avoids the grafting patients are told they need elsewhere.
- Smoking and uncontrolled diabetes materially raise the failure rate and must be addressed first.
Patients who have lost most or all of their teeth usually arrive having tried dentures and disliked them. The complaints are consistent: they move while eating, food gets underneath, certain foods become impossible, and the constant low-level worry that something will slip in company.
Full-arch implant treatment addresses that by fixing the teeth to the jaw. It is a significant undertaking, and worth understanding properly before deciding.
Four implants, not twenty-eight
The idea that a full set of teeth needs an implant per tooth is the commonest misconception, and it is why people assume the cost is impossible.
An entire arch is instead carried on four to six fixtures, positioned where the bone is strongest. The back implants are often placed at an angle, which lets them engage more bone and frequently avoids the sinus lift that a vertical implant would need. A single bridge of twelve teeth is then fixed onto them.
This matters for more than cost. Angled placement means many patients who were told they lacked the bone for implants turn out to be treatable without grafting.
What the treatment involves
It begins with a three-dimensional scan showing exactly where usable bone lies. Any remaining unsalvageable teeth are removed, often on the same day as implant placement.
Surgery is carried out under local anaesthesia, with sedation where a patient is anxious. It takes a few hours per arch. In many cases a fixed temporary bridge is fitted the same day or within a day or two, so you do not leave without teeth — this is what people mean by teeth in a day, and it is genuine, though the bridge is provisional.
Then bone fuses to the fixtures over roughly three to six months, during which the temporary bridge does its job. Once integration is confirmed, the final bridge is made and fitted.
What it feels like afterwards
Swelling and bruising for several days is normal, and most patients describe discomfort as less than expected — comparable to a difficult extraction. A soft diet is necessary while healing, and the temporary bridge is not built for hard or sticky food.
Speech takes a little adjusting to. Most people are speaking normally within a fortnight.
Who it suits, and who it does not
It suits patients who have lost most teeth in an arch, existing denture wearers who cannot tolerate the movement, and people with advanced gum disease whose remaining teeth are not worth saving.
It is not suitable for everyone. Uncontrolled diabetes impairs healing and must be stabilised first. Smoking substantially raises the failure rate, and an honest conversation about that has to happen before treatment rather than after. Certain bone medications used for osteoporosis affect healing and must be disclosed. Some patients simply do not have enough bone even with angled placement, and need grafting first.
A clinic that offers this treatment to everyone who asks is not assessing properly.
Fixed, or removable but stabilised?
There is a middle option that suits some patients better, and it is worth asking about. An implant-supported overdenture clips onto two to four implants: it is removed for cleaning, but it no longer moves while you eat and it does not need adhesive.
It costs less than a fixed bridge, is simpler to clean — which matters if dexterity is limited — and can often be fitted where bone is insufficient for a full fixed arch. What it does not give you is the sensation of teeth that are simply there. Patients who have spent years fighting a loose denture usually want fixed; patients whose main complaint is movement are frequently very happy with an overdenture.
What it does not fix
Fixed teeth are not natural teeth. The bridge sits slightly above the gum and requires deliberate cleaning underneath, daily, with the tools you will be shown. Neglect it and the implants develop the same inflammation that took the original teeth.
It also will not restore a face that has already lost considerable bone height to a flawless profile. It restores function, appearance and confidence very substantially — but a clinic promising a transformation with no qualifications is overselling.
Making the decision
This is not treatment to decide in one appointment. Expect a full examination, a three-dimensional scan, a written plan with staged costs, and time to think. Ask how many arches the surgeon has completed, what happens if an implant fails to integrate, and what the maintenance schedule is.
We provide full mouth rehabilitation at our Khurram Nagar and BKT clinics, planned and carried out by an oral and maxillofacial surgeon. You are welcome to book a consultation to find out whether you are a candidate, including if you have been told elsewhere that you lack the bone.
