TL;DR: Peri-implantitis affects up to 22% of all implant patients after 10 years. In the early stage, it is completely reversible — but only if it is detected. Digital diagnostics significantly increase the detection rate.
What is Peri-implantitis?
Peri-implantitis is an inflammatory disease of the tissue around a dental implant. It is the implantological equivalent of periodontitis — with the difference that implants lack natural defense mechanisms like the periodontal ligament. This makes them more susceptible and the disease potentially more aggressive.
The disease occurs in two stages: Peri-implant mucositis (reversible, soft tissue only) and peri-implantitis (irreversible without treatment, bone loss). The transition is gradual and often asymptomatic.
Prevalence Data: How Common is Peri-implantitis Really?
The data is clear, but the figures vary considerably depending on the study — mainly due to different diagnostic criteria. A meta-analysis by Derks & Tomasi (2015) shows:
| Diagnosis | Prevalence (Patients) | Timeframe |
|---|---|---|
| Peri-implant mucositis | 43% | 5–10 years |
| Peri-implantitis (mild) | 14% | 5–10 years |
| Peri-implantitis (moderate/severe) | 8% | 5–10 years |
| Peri-implantitis total | 22% | 10 years |

Risk Factors: Who is Particularly at Risk?
Not all implant patients have the same risk. The following factors significantly increase the likelihood of peri-implantitis:
- Pre-existing periodontitis: 3-fold increased risk (Heitz-Mayfield et al., 2019)
- Smoking: Significantly impaired wound healing and osseointegration
- Diabetes mellitus: Increased inflammation, slowed healing
- Poor oral hygiene: Biofilm accumulation as primary trigger
- Irregular follow-up: Lack of professional cleaning
Digital Diagnostics: Early Detection with Precision
Conventional diagnostics (probing, radiographs) often only detect peri-implantitis in advanced stages. Digital methods significantly improve early detection:
Treatment: What is Possible?
Treatment depends on the stage. In the mucositis stage, professional cleaning and improved oral hygiene are sufficient — complete reversibility is possible. For peri-implantitis with bone loss, surgical interventions (flap surgery, bone regeneration) are necessary.
The success rate of treatment decreases dramatically with disease progression. This is the decisive reason why early detection is not optional — it is the only way to enable complete healing.
