What are zygomatic implants?
Zygomatic implants are much longer than standard dental implants and anchor in the cheekbone (zygoma) instead of the upper jawbone. They are considered for severe upper-jaw bone loss, when standard implants, tilted implants or grafting are not realistic, and they usually support a fixed full-arch bridge. They are used in the upper jaw only. At Creative Arts in Dubai, suitability is assessed by Dr. Firas Osman, Oral & Maxillofacial Surgeon & Implantologist.
How is a zygomatic implant different from a standard implant?
A standard implant is a screw roughly the length of a natural tooth root, placed into the jawbone where the tooth used to be. It needs enough bone height and width around it to hold firm while the bone integrates.
A zygomatic implant does the same job with a different anchor. It is several times longer, enters at the back of the upper jaw and runs upwards at an angle, past or through the region of the maxillary sinus, until its tip engages the dense bone of the cheekbone. Its head emerges roughly where the premolars or first molars would be, so it can support teeth even when almost no jawbone is left beneath them.
Zygomatic implants are rarely used alone. A common arrangement is one on each side combined with standard implants at the front, where bone is often better preserved; when the front is also severely reduced, two on each side may be considered. All the implants are joined by a rigid full-arch bridge, which spreads the biting load. Because the cheekbone sits above the upper jaw only, this is an upper-jaw technique.
Why does the upper jaw run out of bone?
The bone that holds teeth exists to support them. Once teeth are lost, that bone gradually shrinks, and in the upper jaw two processes work together:
- Ridge resorption. The ridge narrows and flattens over the years after extraction, especially if a denture presses on it.
- Sinus expansion. The maxillary sinus, the air space above the upper back teeth, tends to expand downwards into the space the roots once occupied, leaving only a thin floor of bone.
- Gum disease. Advanced periodontitis destroys bone before the teeth are even lost.
- Failed implants or grafts. Each failure can leave less bone than before.
- Trauma or previous surgery in the upper jaw.
Upper-jaw bone is also naturally softer than lower-jaw bone. That combination, less of it and lower density, is why the upper arch is where the hardest implant cases usually arise.
Zygomatic implants vs the alternatives for a thin upper jaw
A general comparison. A CBCT 3D scan and your health decide which of these are realistic for you.
| Sinus lift + standard implants | Tilted implants (All-on-4 style) | Zygomatic implants | Removable denture | |
|---|---|---|---|---|
| Where support comes from | New bone grown under the sinus floor | Remaining bone, angled to avoid the sinus | The cheekbone, usually with front implants | The gums and palate |
| Bone grafting | Yes | Usually avoided | Usually avoided | No |
| Time to fixed teeth | Longest: graft healing, then implant healing | Implant healing, typically about 3–6 months | Depends on the protocol; decided case by case | Not fixed; made in weeks |
| Surgical complexity | Moderate; sometimes two stages | Moderate | High; deep sedation or general anaesthesia | None |
| Main risks | Sinus membrane tear, graft not taking, infection | Needs enough bone at the front | Sinus problems, gum problems around the implant, rare nerve or eye-socket injury | Movement, sore spots, continued bone loss |
| Often considered when | Bone loss is limited to the back of the upper jaw | Bone loss is moderate and the front is adequate | Bone loss is severe across the upper jaw, or grafts have failed | Surgery is not wanted or not advisable |
Every option on this table has a legitimate place. The least invasive option that reliably meets your goals is usually the right starting point.
Who is considered for zygomatic implants?
Zygomatic implants are considered for severe upper-jaw bone loss. In practice that usually means one or more of the following:
- The CBCT scan shows too little bone at the back of the upper jaw for standard implants, even tilted, and not enough at the front to carry a bridge alone.
- Previous bone grafts or sinus lifts have failed, or implants have been lost along with the bone around them.
- Extensive grafting would be needed, and a long, multi-stage pathway is unsuitable for the patient's health or circumstances.
Equally important is who is not a candidate. If standard or tilted implants can be placed predictably, they are simpler and generally preferred. Untreated sinus disease needs attention first, sometimes with an ear, nose and throat opinion. Uncontrolled diabetes, heavy smoking and some bone-affecting medicines raise the risks of any implant surgery.
Being told you have "no bone for implants" is a reason for a full 3D assessment and a discussion of every option, including a sinus lift or ridge augmentation, not a reason on its own to proceed with zygomatic implants.
Zygomatic implants are not a first choice
Most people with upper-jaw bone loss are treated with standard implants, tilted implants, a sinus lift or grafting. Zygomatic implants are a solution for the cases where those routes are not realistic, which is why the assessment always compares them side by side.
What are the risks of zygomatic implants?
The surgery is more complex than standard implant surgery, works close to the sinus and the eye socket, and is carried out under deep sedation or general anaesthesia. The complications most often discussed are:
- Sinus problems. Inflammation or infection of the maxillary sinus is the complication reported most often, and some cases need treatment from an ear, nose and throat doctor.
- Gum problems around the implant. The gum around the head of a long implant can recede or become inflamed, especially if the implant emerges towards the palate.
- An opening between the mouth and the sinus, which may need repair.
- Numbness of the cheek or upper lip from irritation of a nearby nerve, usually temporary.
- Rare injury near the eye socket, which is why careful 3D planning and experience with the technique matter.
- Harder rescue if an implant fails, because removing a long implant and rebuilding the area is more involved than with a standard implant.
After surgery, swelling and bruising of the cheeks, sometimes reaching the area under the eyes, are common for one to two weeks. Minor nose bleeding can occur, and you are usually asked not to blow your nose forcefully for a period while the area heals.
Zygomatic implants are one route to a fixed full arch. See every option for replacing all your upper or lower teeth, from dentures to implant bridges.
Full mouth implant optionsHow is an assessment for zygomatic implants carried out at Creative Arts?
At Creative Arts in Dubai, zygomatic implants are considered for severe upper-jaw bone loss, and suitability is assessed by Dr. Firas Osman, Oral & Maxillofacial Surgeon & Implantologist. The assessment covers:
- Your history: how the teeth were lost, previous implants, grafts or sinus surgery, current dentures, and your general health and medicines.
- A CBCT 3D scan of the upper jaw, sinuses and cheekbones, showing bone height, width and density, and the health of the sinus lining.
- The bite and the opposing jaw, because a full-arch bridge has to work against whatever it bites on.
- Every realistic option side by side: standard or tilted implants, a sinus lift or bone graft, zygomatic implants, and removable options, each with its timeline, risks and recovery.
If zygomatic implants are recommended, Dr. Firas Osman explains the surgical pathway, the anaesthesia involved and where the operation would take place. You receive a written, itemised plan before any commitment.
Living with zygomatic implants
Day-to-day life with a bridge on zygomatic implants resembles life with any fixed implant bridge: daily cleaning around and under it with a brush, bridge floss or a water flosser, and regular professional reviews using methods that are safe on implants, as described on our implant cleaning page.
Two things deserve extra attention: the sinuses (report persistent congestion, one-sided nasal discharge or pain over the cheek) and the gum around the heads of the long implants, which is checked at every review. Night-time grinding is managed with a protective appliance where appropriate.
Questions to ask before agreeing to zygomatic implants
Whoever you consult, these questions help you judge the recommendation:
- What does my CBCT scan show, and why are standard or tilted implants not enough?
- Would a sinus lift or bone graft be possible, and what would that involve?
- How many zygomatic implants are planned, and will standard implants be used at the front?
- What anaesthesia is involved, and where does the surgery take place?
- What happens if an implant does not integrate or causes sinus problems?
- What provisional teeth will I have, and what maintenance will I need?
Clear written answers are a better guide than any technique name. For four versus six implants on a full arch, see All-on-4 vs All-on-6.
