Guided Bone Regeneration

Guided Bone Regeneration (GBR) is a biologically driven surgical technique aimed at restoring lost alveolar bone to facilitate optimal periodontal health and successful implant rehabilitation. The concept is based on the principle of selective cell repopulation, achieved through the placement of barrier membranes that prevent soft tissue invasion and create a protected space for osteogenic cell proliferation and new bone formation. This book presents a comprehensive overview of the biological principles, wound healing mechanisms, and clinical rationale underlying GBR. It also discusses various barrier membranes and bone graft materials, including autografts, allografts, xenografts, and alloplastic substitutes, along with their indications and limitations. Emphasis is placed on clinical protocols, case selection, surgical techniques, and management of complications. Recent advances in biomaterials, growth factors, and tissue engineering approaches are highlighted, providing insight into the evolving future of bone regeneration. This book serves as a valuable reference for postgraduate students, clinicians, and researchers.
