Mini-review examines nanomaterial strategies for managing implant-associated oral biofilms

A mini-review synthesizes current research on nanomaterial-based strategies for managing peri-implantitis and other implant-associated oral biofilm infections. The approaches discussed include passive surface functionalization, active delivery systems, externally triggered therapies, and host-directed osteoimmunomodulation. These are positioned as potential alternatives to conventional debridement or chemotherapy, which the review notes often fail against mature biofilms. The central premise is that nanomaterials may offer multifunctional strategies to control infection while supporting osseointegration.

No specific study results, sample sizes, or populations are reported, as this is a narrative review of the broader field. The review does not present primary data on efficacy outcomes.

Significant safety and practical limitations are emphasized. Key concerns include the safety of reactive oxygen species (ROS)-based modalities, long-term tribological (wear) performance, manufacturing challenges, and the need for validation in complex, mixed-species biofilms. Long-term biocompatibility also remains a major question. The review suggests practical selection of strategies should be guided by disease stage and host risk factors, but this is a theoretical framework rather than an evidence-based recommendation.

Given the early stage of evidence, high maturity risk, and numerous unresolved technical and safety issues, these nanomaterial strategies are not ready for routine clinical use. They represent an active area of preclinical research that requires rigorous, long-term validation before any translation to patient care can be considered.
