Hard tissue augmentation plays a vital role in periodontal practice, offering solutions for preserving tooth stability, enhancing aesthetics, and facilitating successful periodontal and implant therapy. Guided bone regeneration, bone grafting techniques, and ridge augmentation procedures are essential tools in the periodontist's armamentarium for restoring lost bone volume and supporting periodontal tissue regeneration. Recent advancements in tissue engineering, 3D printing, and regenerative medicine hold promise for further improving the outcomes of hard tissue augmentation in periodontal practice, paving the way for enhanced periodontal and implant treatment outcomes in the future.
