This manuscript introduces a concept that aims to optimise peri-implant health and ensure stability of peri-implant tissues in dental implant therapy. It encompasses the principles of platform switching, restorative abutment design, optimal (internal conical) connection and subcrestal implant placement, and is thus referred to as the PROS concept. Platform switching involves strategic repositioning of the implant–abutment junction to contain inflammatory infiltrate, whereas restorative abutment design emphasises the importance of abutment height and contour in peri-implant tissue stability. Optimal (internal conical) connection focuses on minimising micromovements to reduce microgaps and enhancing stability, and subcrestal placement explores the benefits of implant placement depth on peri-implant tissue health. By integrating these principles, clinicians can enhance the predictability of peri-implant bone stability, leading to successful outcomes in dental implant therapy. This clinical guideline has been developed in accordance with the Appraisal of Guidelines for Research and Evaluation, ensuring methodological rigour and transparency, and enhancing its credibility and usability in clinical practice.
