Peri-implantitis

Full explanation

In depth

The peri-implantitis is inflammation around an implant accompanied by progressive loss of the bone supporting it. The peri-implantitis is the condition that most often ends an otherwise successful implant, and its defining feature for a patient is how quiet it can be: substantial bone loss can occur with little pain, which is why monitoring is based on measurement and radiographs, not on symptoms. Treatment aims to arrest progression and manage the tissues; lost bone is generally not recovered. Regenerative results vary by defect. The peri-implantitis is why the emphasis falls so heavily on prevention and on catching the reversible soft-tissue stage, and why a baseline radiograph at the completion of treatment is worth insisting on. Change can only be judged against a record of where things started. Residual cement left beneath the gum after cementation is a recognized contributor to the disease, which is one argument some clinicians make for screw-retained restorations over cemented ones in patients already carrying other risk factors.

Also called: implant bone loss, implant infection, peri-implant disease.

Detection

Why it is found by measurement instead of symptoms

Pain is an unreliable indicator. The signs clinicians look for are bleeding or suppuration on probing, increasing probing depths, and bone loss visible on radiographs compared with a baseline. None of these are things a patient can assess at home. That makes the monitoring schedule the actual defense, and it makes the baseline record, radiographs taken when the restoration was completed, genuinely valuable years later.

If you did not receive baseline radiographs at completion, ask whether they exist in your records. A current radiograph with nothing to compare it to is considerably less informative.

Risk factors

What is associated with higher risk

FactorDetail
History of periodontitisConsistently identified as a risk factor, which is why implant planning in someone with that history includes a maintenance program from the outset.
Plaque controlInadequate cleaning around the implant is the most direct and most modifiable contributor.
Restoration designA contour that cannot be cleaned makes adequate hygiene impossible regardless of effort.
Residual cementCement left below the gum after cementation is a recognized contributor to peri-implant disease.
SmokingAssociated with poorer outcomes around implants as with periodontal treatment generally.
Irregular maintenanceImplants require their own monitoring interval. Assuming they need less attention than teeth is a frequent error.

Treatment

What management involves

  • Professional debridement using instruments appropriate to implant surfaces
  • Addressing the cause: restoration contour, residual cement, hygiene access, smoking
  • Surgical access in more advanced cases to clean and decontaminate the implant surface directly
  • Regenerative procedures in selected defects, with results that vary by defect shape and extent
  • Reshaping tissue in some cases to create an environment that can be maintained
  • Removal of the implant where support is inadequate and the situation cannot be stabilized

Questions people ask

Common questions

01

Can peri-implantitis be cured?

The goal of treatment is to arrest progression and stabilize the situation instead of restore what has been lost. Bone that has already gone is generally not recovered. Regenerative outcomes vary with the shape and extent of the defect. The peri-implantitis is the reason so much emphasis falls on catching the reversible soft-tissue stage, when bleeding appears but bone loss has not begun.

02

Will I lose the implant?

The peri-implantitis depends on how much support remains, whether progression can be arrested, and how the tissues respond to treatment. Some implants are stabilized and maintained for a long time after treatment; others cannot be saved and are removed. The honest position is that it is assessed case by case, and that early intervention materially improves the range of options available.

03

How would I know I have it?

Often you would not, which is the central problem. The peri-implantitis can progress with little or no pain. The signs are found by a clinician: bleeding or discharge on probing, deepening measurements. Bone change on radiographs against a baseline. That is why the monitoring schedule matters more than self-assessment. Why bleeding around an implant should never be dismissed because it is painless.

04

Does it affect my other implants or teeth?

Each site is assessed individually, but the risk factors are often shared, plaque control, smoking, a history of periodontitis, so finding it at one site is a reason to assess the others and to review the overall maintenance program, not to treat one implant in isolation.

05

Whose fault is it?

Rarely a single party's. The question is less useful than it feels. Contributing factors span hygiene, smoking, a history of periodontal disease, restoration design, residual cement and maintenance frequency. The productive questions are what is driving it in your case, what can be modified. What the plan is if it does not stabilize. Those are answerable; blame generally is not.

06

Is peri-implantitis contagious or can it spread from one implant to another through shared bacteria in the mouth?

The peri-implantitis is not contagious in the sense of an infectious disease transmitted between people, but the bacteria involved are part of the general oral microbial environment shared throughout your own mouth, so poor plaque control affecting one implant site can plausibly influence risk at other sites in the same mouth. An assessment finding it at one implant prompts checking the others for that reason, instead of assuming it's isolated.

07

Can peri-implantitis develop years after an implant was placed with no problems, or does it usually show up early?

The peri-implantitis can develop at any point, including many years after an implant has functioned perfectly well, since it is driven by ongoing factors like plaque control and maintenance consistency instead of something fixed at the time of placement, which is exactly why lifelong monitoring continues to matter, not assuming risk drops to zero once initial healing succeeded.

08

Are there specific antibiotics or medications used to treat peri-implantitis, or is it purely a cleaning-based treatment?

Treatment is generally centered on mechanical debridement and addressing contributing factors, though antimicrobial agents or, in some cases, antibiotics may be used as an adjunct in specific situations to help control the bacterial component alongside the mechanical cleaning: the specific combination of approaches depends on the severity and pattern of the individual case instead of following one fixed protocol.

09

Does peri-implantitis hurt more as it progresses, or does it stay painless even in advanced stages?

It can remain relatively painless well into more advanced stages, which is exactly why it is diagnosed by probing measurements and radiographs instead of by symptoms. Pain, when it does occur, tends to be a late feature, not an early warning sign, reinforcing why routine professional monitoring matters more than waiting for discomfort to prompt a visit.

10

Can removing and replacing the restoration on top of the implant help treat peri-implantitis if the current design is hard to clean?

Yes, in appropriate cases, if the restoration's contour is identified as a contributing factor making adequate hygiene genuinely impossible, remaking it with a more cleanable design can be part of the treatment plan, addressing the underlying access problem instead of only cleaning around a restoration that will keep trapping plaque regardless of effort.

11

Is peri-implantitis more common with certain implant systems or brands than others?

Differences in surface treatment and design between systems can plausibly influence susceptibility to some degree, but patient-level factors, plaque control, smoking, periodontal history, maintenance consistency, are generally considered the dominant drivers across systems, so focusing on those modifiable factors is more useful than assuming one particular implant brand is inherently protective.

12

Can peri-implantitis around one implant in a multi-implant bridge or full-arch prosthesis be treated without affecting the other implants?

Often yes, since each implant can be individually assessed and, where the restoration design allows access, individually treated, but a full-arch or multi-unit prosthesis can make isolating and accessing a single implant more complex than with a standalone crown. The practical treatment approach depends significantly on how the specific prosthesis is designed and whether it can be partially removed for access.
