Craniofacial bone regeneration represents a critical domain within reconstructive surgery, addressing deformities caused by congenital conditions, trauma, severe inflammation, or disease. Traditional methods, such as bone grafts, are often insufficient for restoring extensive or complex maxillofacial defects, particularly those with compromised tissue beds. The lack of vascularization in the initial defect area may also result in cell death and unsuccessful regeneration. This chapter explores evolving strategies in craniofacial bone regeneration, highlighting recent advances in biomaterials, stem cell technology, and tissue engineering, and discusses their potential to enhance therapeutic outcomes. It assesses the efficacy, challenges, and potential future directions of these innovative approaches.
