Complete upper and lower teeth
Full mouth dental implants replace all the teeth in one or both jaws, with either a fixed bridge or a denture that clips onto implants. They may suit you if you have no teeth left, or if most of your teeth have a poor outlook. However, the right design is a choice between trade-offs, not one package for everyone, so your dentist confirms it only after an in-person examination and a CBCT scan.
Full mouth implants at a glance
Typical ranges only. So your dentist confirms your options and timeline after an in-person examination and CBCT imaging.
Full mouth dental implants are not one single treatment. Instead, the term covers several ways to restore a whole arch, in the upper jaw, the lower jaw or both. For example, one jaw may get implants while the other keeps its own teeth.
Next comes the main choice: fixed or removable teeth. Only your dentist takes out a fixed bridge. By contrast, you take out an overdenture each day to clean it. In a 2026 review, both beat a normal denture for quality of life. So your bone, your priorities and your cleaning decide which suits you.

One bridge screwed onto four to eight implants. For example, All-on-4 and All-on-6 are common layouts.
A denture that clips onto small attachments or a bar. Two implants are the agreed minimum in the lower jaw, but the upper jaw needs at least four.
Healthy teeth with a good outlook can often stay. Then your dentist plans implants around them, or treats one jaw and leaves the other.
Suitability is individual. So treat these points as a guide, because a dentist weighs them only after examining you.
Each option trades stability against upkeep. For the lower jaw, UK experts call a two-implant overdenture the minimum standard for most people. In the upper jaw, however, one review found no clear gain over a new, well-made denture.
A common pathway uses two trips to Istanbul. However, grafting or a complex bite can add stages.
First, send photos and an X-ray or CBCT scan for a provisional plan.
Then, in person, your dentist confirms which teeth can stay and which design suits each jaw.
Next, your surgeon removes the teeth with no future and places the implants in one or both jaws.
Depending on how stable the implants are, you leave with fixed or removable temporary teeth.
The implants fuse with the bone over several months, so you eat softer food. Meanwhile, remote check-ins help.
Finally, your dentist takes new scans and fits the final bridge or overdenture.
Eat soft food while the implants heal. Later, a fixed bridge gives the firmest bite, while an overdenture still chews better than a loose denture.
With a fixed bridge, clean under it every day. With an overdenture, however, take it out and clean the implants and clips. Either way, poor cleaning can inflame the gums and, over time, cost you an implant.
See a dentist or hygienist every 3 to 6 months. At these visits, your dentist checks the gums, the screws and any clips that wear.
Studies report high survival for full-arch treatment. For example, in one large review, 95.2% to 99.2% of implants lasted 5 to 15 years. Fixed bridges lasted in 89.5% to 96.8% of cases. Even so, survival does not mean problem-free, because repairs are a normal part of owning full-arch teeth.
The number of implants matters too. In a review of 54 studies, implants under fixed bridges failed less often than under overdentures. Also, upper jaw implants failed more often. So ask why your plan uses that number.
NHS information says over 90% of implants bond with the jawbone. However, smoking lowers the odds, so stop at least six months before treatment.
In one review, upper overdentures on fewer than four implants lost implants about three times as often. For this reason, experts advise at least four in the upper jaw.
On fixed bridges, veneered zirconia chipped in 15% to 35% of cases in long-term reviews. Similarly, screws loosened in 5% to 15%.
Clips wear and dentures need adjusting, so overdentures need regular upkeep. However, close follow-up keeps these problems in check.
Plaque can inflame the gums around implants. When bone loss follows, dentists call it peri-implantitis. Full-arch reviews found it in 4% to 18% of patients.
Numbness after surgery is very rare and usually settles, although very rarely it is permanent. Similarly, severe bleeding is extremely rare.
Before you book, ask any clinic, including us, for clear written answers.
Not always. For example, many people treat a loose lower denture and keep their own upper teeth. Your dentist also checks how the jaws bite together.
Not for everyone. In a 2026 review, fixed bridges gave a firmer bite but needed more upkeep. However, overdentures were easier to clean.
It depends on the jaw and the design. Two implants can hold a lower overdenture. In the upper jaw, however, reviews advise at least four.
Often two, several months apart. First, your dentist examines you and places the implants. After healing, you return for the final teeth.
In long-term reviews, 95.2% to 99.2% of implants lasted 5 to 15 years. However, no one can promise a lifetime, because the teeth wear and may need repair.

Send a recent panoramic X-ray or CBCT scan and a few photos of your smile. A dentist will then review them and explain which option looks suitable. Your plan stays provisional until your dentist examines you in person.
