Guided Bone Regeneration (GBR) is a crucial technique for implant site development, designed to restore alveolar bone volume in cases of deficiency. It involves the use of barrier membranes to protect the healing environment, allowing bone growth while preventing soft tissue infiltration. GBR enhances ridge augmentation, socket preservation, and defect repair, ensuring optimal implant stability and long-term success. Careful selection of graft materials, membrane stability, and surgical techniques contributes to predictable outcomes, improving both functional and aesthetic results. Advances in minimally invasive approaches continue to refine guided bone regeneration (GBR), making it a cornerstone of modern implantology.
