Smart implants with embedded biosensors for early detection of peri-implantitis

Abstract

Smart implants with embedded biosensors represent an emerging approach to improving the early detection and management of peri-implantitis. Conventional diagnostic methods primarily depend on clinical examination, probing, radiographic assessment, and detection of established tissue changes, which may limit the identification of early biological disturbances. Smart implant technology integrates miniature biosensors capable of monitoring local physiological and biochemical parameters, including temperature, pH, inflammatory biomarkers, microbial activity, and mechanical loading. These sensors can provide continuous or periodic information regarding changes in the peri-implant environment, potentially allowing inflammatory and infectious processes to be recognized before substantial bone destruction occurs. Integration with wireless communication, digital dentistry, and Internet-of-Things platforms may facilitate remote data transmission and longitudinal monitoring of implant health. Furthermore, combining sensor-generated information with radiographic imaging and clinical parameters could support individualized risk assessment and preventive intervention. Despite these advantages, challenges remain regarding sensor miniaturization, biocompatibility, durability, calibration, power supply, data security, and long-term clinical reliability. Future developments may incorporate multimodal biosensing and artificial intelligence to transform smart implants into predictive diagnostic systems. Overall, embedded biosensors have significant potential to shift peri-implantitis management from reactive diagnosis toward proactive, personalized, and continuous implant monitoring.
