In response to the frustration of applying conventional treatments that so often fail on contaminated surfaces, this work by Dr Eduardo Anitua proposes a surgical and biological paradigm shift. The book provides a clear clinical algorithm that guides precise decision-making at each stage of disease severity: from strengthening the tissue seal and correcting the emergence profile in the early phases, to performing clean implant removal without bone loss using the counter-torque system. It explains how to regenerate the receiving bed effectively with plasma rich in growth factors (PRGF-ENDORET®) and restore function predictably, even with immediate reimplantation. Supported by an extensive series of real clinical cases documented step by step, this manual is an indispensable tool for managing complex situations with complete confidence.
