Comparative Bone Graft Evaluation for Dental Implant Success: An Evidence-Based Review

In this review, we provide a comparative evaluation of different bone grafts for dental implants success. We performed a literature review to analyze dental implant success and survival rates after the use of various grafts for bone augmentation. A total of 41 studies were selected and analyzed based on parameters including study design, number of implants placed, total number of participants, type of graft used, site from which graft was obtained, time elapsed between bone augmentation and implant placement, implant survival, and success rates. Results indicate that after a follow-up period of 1-5 yr, respective success and survival rates are as follows: block grafts, 91.5% and 75%; blood derivatives, 91.5% and 96.7%; composite grafts, 80.9% and 94.2%; xenografts and particulate grafts, 100% for both success and survival. After evaluating the available studies, we can report that autologous block grafts, composite grafts, and blood derivatives were the most commonly used grafting materials for bone augmentation before placing dental implants. Xenografts and particulate grafts had 100% success and survival rates, but more studies are needed to assess the impact of these grafting materials.
