Biomarker‑guided risk scoring for peri‑implantitis: a practical take for the busy clinic
A retrospective long‑term study shows a biomarker‑guided score identifies a small high‑risk group with nearly fivefold greater hazard for peri‑implantitis — a tool you can use to target maintenance and avoid over‑treating low‑risk patients.

A new long‑term retrospective study applied a biomarker‑guided implant risk score to patients followed in routine private care and reports results that are directly relevant to how we schedule maintenance. In 80 partially edentulous patients with a mean implant follow‑up of 10.5 years, overall peri‑implantitis incidence was 17.5%; 27.6% of patients fell into the model’s “high‑risk” category and the high‑risk score was associated with a hazard ratio of 4.8 for peri‑implantitis (area under the ROC curve 0.84). These numbers suggest the score separates a minority of patients who carry substantially greater long‑term risk. ([lifescience.net](
Clinical takeaways
- A simple biomarker‑guided score can flag ~25–30% of patients as high risk; those patients had about a fivefold higher hazard for peri‑implantitis in the reported cohort.

- Use point‑of‑care sulcus biomarker testing as an adjunct to clinical risk assessment (history of periodontitis, smoking, plaque, prosthesis design) to personalise recall — increase visits and cleaning for high‑risk patients and avoid unnecessary interventions for low‑risk ones.

- Before you adopt: recognise the study was retrospective and modest in size; validate the tool against your patient mix and keep patient education simple — many patients remain unaware of peri‑implantitis and will not volunteer symptoms. Structured maintenance and clear communication are essential.
