Age, Health & Zygomatic Implants: Who Is Suitable?

Implants fuse with bone through osseointegration, and that process does not switch off with age. Older bone can integrate implants successfully; what changes with age is the likelihood of carrying other health conditions and taking medication that affects healing. It is those conditions, not the years, that shape the decision.

There is also a practical point that cuts the other way. Many people who most need zygomatic implants are older, precisely because the bone loss that rules out standard implants takes decades of denture wearing to develop. Treating age as a barrier would exclude exactly the group the technique was designed for.

What older patients are more likely to need is a more careful pre-operative work-up — a proper look at medication, cardiovascular fitness and anaesthetic risk — rather than a different implant plan.

The one place where age genuinely is the criterion is at the young end. Implants are fixed in bone and do not move, while a growing jaw does. Placing an implant before facial growth is complete can leave it out of position as the surrounding bone continues to develop.

Clinics therefore wait until skeletal growth has finished, which is assessed individually rather than by a fixed birthday — growth completes at different times for different people, and typically later in men than in women. The published position is that osseointegrated implants are generally contraindicated until craniofacial growth has been completed, because an implant placed earlier behaves like an ankylosed tooth while the jaw around it keeps developing, producing infraocclusion and interfering with alveolar growth.

In practice this rarely affects zygomatic candidates, who are overwhelmingly adults with long-standing bone loss. This page covers age, medication and fitness for anaesthesia; for the full set of criteria — including how much bone is needed and what rules treatment out — see who is and is not a candidate.
