Effect of Symphysis Onlay Bone Graft, Injectable Platelet Rich Fibrin (I-PRF) and Xenograft on Horizontal Alveolar Ridge Augmentation in Esthetic Zone

The aim of the study: was to evaluate whether mandibular symphysis Onlay autogenous bone graft mixed with Injectable PRF could offer any advantages for patients undergoing horizontal alveolar ridge widening regarding increase alveolar ridge width compared to mandibular symphysis Onlay autogenous bone graft mixed with Xenograft

Alveolar bone resorption is one of complications post-extraction complications where there is a reduction in the dimensions and quality of the alveolar bone. Alveolar bone resorption is known to occur over time, but resorption in the first few months of tooth extraction is known to be very significant. The ideal bone graft material should have osteoconductive, osteogenic, and osteoinductive properties and mechanical stability and be free from disease. Osteoconductive is a physical property of a material that provides a framework for the growth of blood vessels and osteoprogenitor cells in bone formation. Osteoinductiveness is the ability to stimulate stem cells to differentiate in mature cells through stimulation by local growth factors. Osteogenicity is the bone growth factors in bone grafts. Growth factors from PRF such as platelet-derived growth factor (PDGF), transforming growth factor (TGF), and insulin growth factor (IGF) are known to play a significant role in healing and bone regeneration to prevent excessive alveolar resorption after tooth extraction.
