Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

Résumé fourni par la source

Dental implants are a common and effective solution for tooth loss. However, achieving consistent soft tissue integration (STI) remains a significant challenge, affecting their long‐term performance. A robust soft tissue seal around implants is essential for protecting against bacterial infection, thereby reducing the risk of peri‐implantitis and potential implant failure. Yet, replicating the natural tooth–gingiva interface continues to be difficult. Recent advances in material science—particularly surface modifications of titanium implants—have shown promise in enhancing gingival cell attachment and mimicking native tissue architecture. The strength of this interface is crucial for mitigating gum recession, and maintaining this seal is key to improving implant longevity and, ultimately, the quality of life for individuals without natural dentition. This review highlights the biological importance of soft tissue sealing and explores the key factors influencing integration at the implant interface, including bacterial colonisation and the role of implant surface properties. We summarise current strategies—ranging from surface chemistry and topography to biological coatings and emerging cell‐based approaches—aimed at improving STI. Overall, this review offers an up‐to‐date material science perspective on enhancing the long‐term success of titanium dental implants.
