A facial implant is two decisions, and most consultations discuss only one. The design — the shape, the projection, the way it meets the bone — is what patients ask about, and rightly. The material is the quiet half, and it decides things the design cannot: whether the implant can be removed in fifteen years, whether a future scan can see through it, and whether the bone beneath it stays as strong as it was.
I use PEEK for custom facial implants in Dubai, and this article explains why. It also explains what PEEK costs you, because a surgeon who names only the advantages of his own material is describing a product rather than a material.
Key takeaways: the material, judged honestly
- PEEK is stiff like bone, so it does not shield the bone beneath it.
- It is bioinert: it will not integrate, so it must be screwed rigidly.
- It is radiolucent, so a future scan reads the skeleton, not the implant.
- Complications in 18% across 194 patients in the review.
- No coated or modified PEEK has been reported in facial surgery.
- It is a good material honestly described, not a perfect one.
A note on scope: this article is about the material. How a chin implant changes facial proportion is covered in my article on chin implant materials and facial proportions, how a bespoke implant is designed from a scan in my article on custom chin implants and jawline balance, and what the soft tissue does afterward in my article on relapse after chin surgery.
What recommends PEEK
Polyetheretherketone is a high-performance polymer, used in spinal and craniofacial surgery for decades before it reached aesthetic work. Four properties recommend it for the face.
- Stiffness like bone. Its elastic modulus is comparable to cortical bone, so it behaves mechanically much as the skeleton it sits on. A material far stiffer than bone can absorb the load the bone should carry, and bone that is not loaded thins. PEEK does not do that.
- Bioinertness. The body neither attacks it nor bonds to it. It provokes little inflammation and does not degrade.
- Radiolucency. It is transparent to X-rays and compatible with CT and MRI, producing none of the scatter that a metal implant throws across an image.
- Precision. It can be milled or printed to one person’s anatomy, and adjusted intraoperatively with a standard burr if the fit needs refining.
What it costs you
Every one of those properties has a price, and the second one has the largest.
PEEK does not osseointegrate. A thin fibrous layer forms at the interface rather than a bond to bone, so the implant is held by fixation rather than by biology. That is why I screw a PEEK implant rigidly to the skeleton rather than seating it in a pocket and trusting the tissue to hold it. Done that way, it is stable. Done loosely, it would not be.
A systematic review of PEEK patient-specific implants reported an eighteen percent complication rate across 194 patients. That is a real number, and I would rather quote it than a comfortable one.

The same property, read twice
Bioinertness is the interesting case, because it is the same fact stated as a weakness and as a strength.
As a weakness: the implant never becomes part of you, and depends on screws and a clean pocket for its stability.
As a strength: the implant can be removed, years later, without cutting bone away. An integrated implant has to be separated from the skeleton it has grown into. A PEEK implant comes out by removing screws and lifting it, leaving the bone as it was.
For surgery that nobody medically needs, on a face, that property seems to me to matter a great deal. A decision you can revisit is a better decision than one you cannot.
| Property | What it gives you | What it costs you |
|---|---|---|
| Bone-like stiffness | No stress shielding | Less strong than titanium |
| Bioinert | Removable in future | Never integrates; needs screws |
| Radiolucent | Clean CT and MRI | Invisible on a plain X-ray |
| Custom-milled | Fits one skeleton | Planning time and cost |
What the evidence supports, and what it does not
A single-centre series of 44 implants in 37 patients, followed over a mean of 78 months, recorded no implant dislocation, no rupture, and no long-term infection. That is a reassuring durability signal over a genuinely long interval.
What the evidence does not yet support is the improvement everyone is waiting for. Coatings — hydroxyapatite, titanium — do improve integration in laboratory and spinal work. In facial surgery, no coated or modified PEEK implant has been reported at all. It is a direction, not an option, and I would rather tell you what exists.
Why radiolucency is a patient’s argument, not a surgeon’s
This one is easy to skip past, and it matters more than it sounds.
If you ever need a CT of the facial skeleton — after an accident, for a sinus problem, for anything — a titanium implant throws a bright shadow across the image, and the radiologist reads around it. A PEEK implant is simply not there. The bone is seen as bone.
You are choosing an implant for a face you will have for fifty years, during which you will probably be scanned for something. Not compromising that seems a reasonable thing to want.
So is it the best material?
No material is best. A material is matched to a purpose, and the purpose here is a custom implant, on a face, that may one day need to come out, in a person who may one day need a scan.
For that purpose, PEEK is the one I reach for, and I have told you what it costs. If a surgeon offers you a material and names only its advantages, ask him what it costs you. The answer, and whether he has one, will tell you a great deal. That is the standard I hold in my practice in Dubai, and my approach to the operation itself is set out on my page about chin surgery in Dubai.
FAQs about PEEK facial implants in Dubai
-
What is PEEK, and why is it used for facial implants?
PEEK is polyetheretherketone, a high-performance polymer used in spinal and craniofacial surgery for decades. What recommends it for the face is its stiffness. Its elastic modulus is comparable to cortical bone, so it behaves mechanically much as the skeleton it sits on. It holds its shape, tolerates load, and can be milled or printed to one person’s anatomy. So it is not a new or exotic material. It is an established one that happens to suit the face.
-
Does PEEK integrate with the bone?
No, and this is the honest limitation. PEEK is bioinert: the body neither attacks it nor bonds to it, and a thin fibrous layer forms at the interface instead of true osseointegration. So the implant is held by fixation rather than by biology, which is why I screw it rigidly to the skeleton rather than relying on the pocket to hold it. Done that way it is stable. Left loose, it would not be.
-
Is bioinertness a disadvantage?
It is both, and I would rather you heard both halves. Because it never integrates, PEEK can be removed years later without cutting bone away, which is a genuine advantage in elective surgery you may one day change your mind about. Because it never integrates, it depends entirely on the screws and on a clean pocket. So the same property that makes it reversible makes it unforgiving of loose fixation. The answer is not a different material; it is fixation done properly.
-
Why does radiolucency matter to me?
Because of the scan you have not needed yet. PEEK is transparent to X-rays and compatible with CT and MRI, so it produces no scatter and no metal artefact. Titanium does. If you ever need imaging of the facial skeleton, for a fracture, a sinus problem or anything else, the radiologist reads the bone rather than a bright shadow across it. So it is not an aesthetic argument at all. It is about not compromising your future medical care for the sake of today’s contour.
-
How common are complications with PEEK facial implants?
The best available review reports complications in eighteen percent of 194 patients receiving patient-specific PEEK implants. That is a real number and I will not soften it. It is also drawn largely from case reports and reconstructive series, which tend to describe difficult cases rather than routine ones. So the figure sets an outer bound rather than describing what a straightforward chin augmentation carries. Ask any surgeon for his own rate, and treat a claim of zero with suspicion.
-
Are coated or modified PEEK implants better?
In laboratory and spinal work, coatings such as hydroxyapatite and titanium do improve integration. In facial surgery, no coated or modified PEEK implant has been reported at all. So this is a promising direction rather than an available option, and any surgeon offering you a coated facial PEEK implant today is describing something the literature has not yet seen. I would rather tell you what exists than what may exist.
-
Is PEEK better than titanium or porous polyethylene?
Better at some things, and not at others. PEEK is stiffer than polyethylene and does not shield bone the way a metal can, and it images better than titanium. Titanium is stronger and integrates. Porous polyethylene allows tissue ingrowth, which makes it stable and makes removal harder. So there is no best material, only a material matched to a purpose. For a custom facial implant that may one day need to come out, and for a face that may one day need a scan, PEEK is the one I reach for.
-
Can a PEEK implant be removed if I change my mind?
Yes, and that is a large part of why I use it. Because PEEK does not bond to bone, removal means taking out screws and lifting the implant, not chiselling an integrated device off the skeleton. The bone beneath is left as it was. So an elective operation on a face remains an operation you can reverse, which seems to me the right property for surgery nobody medically needs. I would not want to give you a decision you cannot revisit.
