  In restorative dentistry, dental implants have emerged as a groundbreaking solution for replacing missing teeth and restoring smiles. However, successful dental implantation relies heavily on having a strong and healthy foundation of bone to support the implant. This is where dental bone graft and substitutes play a vital role. Dental bone grafts involve the transplantation or addition of bone tissue to areas where the patient's natural bone is insufficient to support an implant. This procedure is commonly used in cases where bone loss has occurred due to tooth extraction, gum disease, or trauma. The graft material can be sourced from the patient's own body (autograft), a donor (allograft), or synthetic materials (alloplastic grafts). The role of bone grafts is to stimulate bone regeneration and growth, providing a solid base for the dental implant. The grafted bone acts as a scaffold, encouraging the patient's bone cells to populate the area and integrate with the graft...
