There’s a group of patients who have been hearing the same thing for years: that nothing can be done. They’re people who lost all their upper teeth a long time ago, who have worn dentures for years, and who were told they don’t have bone for implants. Often they were offered a large graft, got frightened by the time and cost, and that’s where it ended. For several of those cases, zygomatic implants exist. Let me explain what they are, when they’re justified and when they’re not.
Why the upper jaw runs out of bone
The bone where your roots used to be exists because those roots stimulated it. When the root disappears, the bone loses its function and resorbs. It’s a normal, progressive process. In the upper jaw that process is more pronounced for two reasons. First, because the bone up top is naturally less dense than the bone below. And second, because above it sits the maxillary sinus, an air cavity that tends to occupy the space the bone leaves behind. Over the years that leaves a strip of bone so thin that a conventional implant has nowhere to anchor.
What a zygomatic implant is
It’s an implant much longer than a conventional one — several centimeters — that passes through the maxillary area and anchors into the zygomatic bone, the cheekbone. The reason it works is simple: the zygomatic bone doesn’t resorb. It doesn’t depend on teeth, it doesn’t lose volume over the years and it’s dense bone. It’s there, available, no matter how long you’ve been without upper teeth. It’s the same principle we always look for in implantology — anchoring in good-quality bone — applied to a different area.
When they’re indicated and when they aren’t
I want to be clear about this because it matters: zygomatic implants are not a first option,
and anyone who proposes them as a first measure without having evaluated the rest is
skipping steps. In my practice the order is this:
First, conventional implants. If there’s enough bone, there’s no reason to complicate the case.
Second, strategic angulation. Tilting the implants to use the areas of dense bone that still remain, generally toward the front. This resolves a great many cases that seem impossible and avoids grafts. It’s the technique I most frequently use in patients who arrive with the “you have no bone” diagnosis.
Third, zygomatic implants. When resorption is so severe that not even angulation finds anywhere to anchor. That’s the practical difference: angulation takes advantage of the bone that remains; the zygomatic goes looking for bone elsewhere because there’s nothing left to take advantage of.
What the treatment looks like
Diagnosis. A CT scan is mandatory, here more than in any other case. We have to evaluate the volume of the zygomatic bone, the anatomy of the sinus and the relationship with neighboring structures. On that image the full trajectory of each implant is planned.
Surgery. It’s a procedure of greater complexity than a conventional placement and requires specific training. The implant trajectory is long and passes near structures that demand precision.
Immediate loading. One of the advantages of these implants is that they usually achieve very good initial stability, which in many cases allows a fixed temporary prosthesis to be placed within days. For a patient who has spent years with a removable denture, that’s a major change.
Combination. They’re frequently not used alone: two zygomatic implants are combined with conventional implants in the front area, where bone still remains. Each arch is resolved with the combination its anatomy allows.
Follow-up. As with any full rehabilitation, checks every 4 to 6 months.
What has to be said honestly
It’s a demanding technique and it isn’t free of considerations. The complication most frequently described in the literature is involvement of the maxillary sinus, and its prevention depends on planning and surgical technique. It also requires careful management of the surrounding soft tissues, and its long-term maintenance demands hygiene discipline. It’s a higher-cost procedure than a conventional rehabilitation, precisely because of the complexity and what it demands in planning. That’s why I insist on the order: if your case can be resolved with angulation, it’s resolved with angulation.
What to ask
1. Why aren’t conventional or angled implants enough in my case? 2. Can I see on my CT scan why this indication is reached? 3. How many zygomatic and how many conventional implants does my plan include? 4. Will I leave with a fixed temporary prosthesis? In how many days? 5. What specific training does the person performing the surgery have? 6. What does follow-up look like and how often?
Closing
If you were told years ago that you had no bone and you’ve since resigned yourself to a removable denture, that diagnosis deserves a review. Implantology today isn’t what it was two decades ago, and a significant share of the cases that were once dismissed now have a solution. Your case may be resolved with angulation, which is less complex, or it may require zygomatic implants. Come in with a CT scan and we’ll review it. And if there’s no indication, I’ll tell you that too.
Frequently asked questions
Do zygomatic implants hurt more? The surgery is performed under anesthesia and with the management appropriate to its complexity. Recovery usually includes swelling in the area for several days. How long do they last? By anchoring in bone that doesn’t resorb, they offer long-term stability. Like any implant, they depend on maintenance and follow-up. Can it be done if I have sinusitis? It’s a condition that must be evaluated and treated first. It’s determined case by case with the CT scan. Do they work for the lower jaw? No. They’re a specific solution for severe atrophy of the upper jaw. Below, the anatomy and the alternatives are different.
