Peri-Implantitis: Why Implants Fail, and How Titanium and Ceramic Compare

The short answer: Peri-implantitis is inflammation of the tissue around a dental implant that, left unchecked, destroys the bone supporting it. It is the leading cause of late implant failure, the reason an implant that worked well for years can loosen and be lost. It is driven mainly by bacterial biofilm building up around the implant, made worse by poor oral hygiene, smoking, uncontrolled diabetes, leftover cement, and poor implant positioning. It affects both titanium and ceramic implants. There is reason to think ceramic (zirconia) may carry some advantage, because it attracts less plaque and tends to integrate very well with the surrounding gum, but the honest picture is that prevention, planning and maintenance matter far more than the material alone. Catching it early is everything, because bone lost to peri-implantitis does not grow back on its own.

What peri-implantitis actually is

An implant, like a natural tooth, sits surrounded by gum and anchored in bone. When bacteria accumulate at the gum line around an implant, the tissue becomes inflamed. This has two stages:

• Peri-implant mucositis is the early, reversible stage: the gum around the implant is inflamed, often bleeds, but the bone is still intact. Caught here, it can usually be resolved.

• Peri-implantitis is the advanced stage: the inflammation has spread to the bone, which begins to resorb around the implant. As the bone is lost, the implant loses support, and eventually it can loosen and fail.

The critical point is that mucositis is a warning, and peri-implantitis is damage. The whole aim is to catch and stop the process before bone is lost, because unlike the gum, the bone does not simply recover once it is gone.

What causes it

Peri-implantitis is fundamentally an infection driven by bacterial biofilm, but several factors raise the risk:

• Poor oral hygiene, which allows biofilm to build up around the implant. This is the single biggest controllable factor.

• Smoking, which impairs healing and blood supply to the gum and bone.

• Uncontrolled diabetes and other conditions that affect healing and immunity.

• A history of gum disease (periodontitis), which strongly predicts implant problems.

• Residual cement left under the gum during crown fitting, which acts as a trap for bacteria.

• Poor implant positioning or an ill-fitting restoration, which makes the area impossible to clean properly. This is where planning and surgical skill matter enormously.

• Lack of regular maintenance and professional check-ups, so early problems go unnoticed.

Notice how many of these are controllable. Peri-implantitis is largely a preventable and manageable condition when an implant is well planned, well placed and well maintained.

Titanium vs ceramic: does the material matter?

This is a fair and important question, and it deserves an honest, measured answer rather than a sales pitch.

Peri-implantitis affects both titanium and ceramic implants. No implant material makes you immune to it, and good hygiene and maintenance are essential whichever you choose.

That said, there are reasons ceramic (zirconia) may offer some advantage:

• Lower plaque affinity. Zirconia tends to accumulate less bacterial biofilm than titanium, and biofilm is the root driver of peri-implantitis.

• Favourable soft-tissue response. Gum tissue integrates very well around zirconia, and a good soft-tissue seal is part of the defence against bacteria reaching the bone.

• No metal corrosion or particle release. Titanium can, in some circumstances, release micro-particles into the surrounding tissue, and there is ongoing research into what role this may play in inflammation. Zirconia is bioinert and does not corrode.

Here is the honest caveat. Titanium has decades more long-term data, and while these properties of zirconia are promising, large long-term comparative studies on peri-implantitis rates are still developing. So the responsible position is this: ceramic may carry advantages relevant to peri-implantitis, but material choice is not a substitute for the things that truly determine risk, which are planning, positioning, hygiene and maintenance. A poorly placed ceramic implant in a patient who does not maintain it is at more risk than a well placed, well maintained titanium one.

The warning signs

Peri-implantitis is often painless in its early stages, which is exactly why regular monitoring matters. Signs to be aware of include:

• Redness or swelling of the gum around the implant.

• Bleeding when brushing around the implant.

• Gum receding, or the implant starting to look longer.

• Pus, or a bad taste around the implant.

• In later stages, looseness of the implant, which is a serious sign.

If you notice any of these around an implant, it should be assessed promptly. Early action can mean the difference between a simple clean-up and losing the implant.

How it is diagnosed and treated

Diagnosis combines a clinical examination, measuring the depth of the tissue around the implant and checking for bleeding, with imaging. A CBCT 3D scan shows the pattern and extent of any bone loss precisely.

Treatment depends on the stage:

• Early (mucositis): thorough professional cleaning and improved home care can often resolve it.

• Established peri-implantitis: treatment aims to decontaminate the implant surface and control the infection, sometimes with a surgical approach to clean the area, and in some cases regenerative procedures to rebuild lost bone. A biological approach uses tools such as ozone and PRF to support healing.

• Advanced/failing implant: where too much bone has been lost, the implant may need to be removed. After healing, and often bone regeneration, a new implant can usually be placed.

The earlier it is caught, the simpler and more successful the treatment.

How to prevent it

The good news is that peri-implantitis is largely preventable:

• Excellent daily hygiene around implants, as advised for your specific restoration.

• Regular professional maintenance visits, so early inflammation is caught and treated before bone is affected.

• Not smoking, and controlling conditions such as diabetes.

• Well-planned, well-placed implants and restorations that can actually be kept clean, with no leftover cement. This starts with the implantologist.

• Choosing biocompatible materials as part of a whole-mouth, biological approach to long-term implant health.

An implant is not “fit and forget.” It is a long-term restoration that, cared for properly, can last decades.

Frequently asked questions

Is peri-implantitis common? It is one of the most common long-term complications of dental implants, which is why prevention and regular maintenance are so important. Most cases are avoidable with good planning, hygiene and check-ups.

Can peri-implantitis be cured? If caught at the early, gum-only stage (mucositis), it can usually be resolved. Once bone is lost, treatment aims to stop the progression and, where possible, regenerate bone, but bone already lost does not return on its own. Early detection is key.

Do ceramic implants get peri-implantitis? Yes, they can. No implant is immune. Ceramic may carry some advantages because it attracts less plaque and integrates well with the gum, but good hygiene and maintenance remain essential regardless of material.

Will I feel it if I have peri-implantitis? Often not in the early stages, which is why it is sometimes missed. It can progress painlessly, so regular professional monitoring, not just symptoms, is how it is caught in time.

My implant feels loose. What should I do? See your dentist promptly. A loose implant is a serious sign that should be assessed without delay, as early intervention gives the best chance of saving it or planning the right next step.
