Advancing the diagnosis of peri‐implant diseases: From histological foundations to next‐generation ultrasonographic diagnostic markers

Peri-implant diseases can affect the tissues around dental implants and can lead to inflammation and bone loss. Understanding how these diseases develop and how best to diagnose them is essential for improving patient care. The present narrative review looked at scientific studies that examined the tissues around implants and the methods used to diagnose peri-implant diseases. It explains what researchers have learned from tissue (histological) studies and summarizes the current clinical and X-ray based diagnostic standards. It also highlights new advances in high-frequency ultrasound (HFUS), a technology that can provide detailed, real-time images of the soft tissues and bone around implants without radiation. Recent studies show that HFUS can measure tissue thickness, detect inflammation, visualize blood flow, and help identify early bone defects. These ultrasound features match what is known from histology, suggesting that HFUS could become an important tool for detecting peri-implant disease earlier and more accurately. Overall, adding HFUS and power Doppler imaging to current diagnostic methods can improve the evaluation of peri-implant tissues. These noninvasive techniques can help clinicians see key structures more clearly, assess inflammation, and better understand the severity of the disease.
