Am I a Candidate for Zygomatic Implants?

The core indication is narrow and well described. The 2023 ITI consensus report states that zygomatic implants are "mainly indicated in cases with maxillary bone atrophy or deficiency" — in plain terms, an upper jaw that has shrunk or been lost to the point where conventional implants have nothing to hold onto. [1]

In practice that covers a recognisable group: long-term upper denture wearers whose ridge has flattened over years, people who have lost upper teeth to advanced gum disease, patients whose previous implants or bone grafts have failed, and those who have lost jaw structure to trauma or to cancer surgery. What they share is not a diagnosis but a measurement — there is not enough bone in the upper jaw, and the cheekbone above it is intact.

You do not need to have lost every upper tooth. Many plans combine zygomatic implants at the back, where bone loss is usually worst, with standard implants at the front where some bone often remains. Which configuration suits you is a question about your anatomy, not about how bad things feel.

It is worth being precise about language, because clinics use these terms loosely. An absolute contraindication means treatment should not go ahead at all. A relative contraindication means the risk is raised and has to be managed, discussed and sometimes traded off — not that the door is closed.

Very few things fall into the first category. The ones that do tend to be structural or situational rather than a matter of general health: no usable zygomatic bone on the scan, an active untreated infection at the surgical site, or being unable to undergo the anaesthesia the operation requires.

Almost everything else patients worry about — age, diabetes, smoking, having had implants fail before — sits in the second category. That distinction matters, because being told "you are not suitable" without being told which kind of unsuitable is meant leaves you unable to act on it. Each has its own guide: smoking, diabetes, and what happens when an implant fails.

Everything above narrows the field. None of it settles the question, because the deciding factor is a measurement that cannot be estimated from the outside: how much bone remains in your upper jaw, and what the zygomatic bone above it looks like in three dimensions.

A cone-beam CT scan shows the height and width of remaining bone, the shape and health of the maxillary sinus, and the position of the structures a surgeon has to avoid. That is what a treatment plan is built from. A panoramic X-ray is a useful first look but it flattens a three-dimensional problem into two, which is why it can suggest possibilities but not confirm them.

This is also why the sequence matters. A scan first, then a plan, then a price. If a price arrives before a scan, what you have been given is a starting position rather than an assessment — see how to check a surgeon for the questions that expose the difference.

A large share of people who end up having zygomatic implants were told at some point that implants were impossible for them. That statement is usually accurate about the treatment being discussed at the time — standard implants in a jaw that cannot hold them — and not about every option that exists.

It also runs the other way, and this deserves saying plainly: being told you are suitable is not the same as being told this is your best option. Grafting remains the more thoroughly studied route for people who have enough bone to rebuild, and a well-made denture is a legitimate choice rather than a failure. Every option when you have bone loss sets those side by side.

The published evidence is also consistent on one point that has nothing to do with your anatomy: this is a technique-sensitive operation and outcomes track the surgeon. One overview of systematic reviews concludes it "should be reserved only to professional clinicians with vast surgical experience and a good knowledge of the 3D anatomy". Whoever assesses you should be someone who does these regularly. [7]
