Mesenchymal Stem Cells in Oral and Maxillofacial Surgery: A Systematic Review of Clinical Applications and Regenerative Outcomes

Aim This systematic review aims to evaluate the use of mesenchymal stem cells, particularly those derived from bone marrow, adipose tissue, and dental pulp in maxillofacial and oral surgery, focusing on their regenerative potential, clinical applications, and integration with biomaterials. Introduction: Mesenchymal stem cells are multipotent stem cells known for their immunomodulatory and regenerative abilities. Their low immunogenicity and differentiation capacity make them ideal for treating craniofacial defects and enhancing soft tissue repair. Materials and Methods The review followed PRISMA guidelines and was registered in PROSPERO. The literature was searched across PubMed, Scopus, and Web of Science from 2009 to 2024. Twelve studies met the inclusion criteria and were analyzed for clinical efficacy and methodological quality. Results Clinical trials demonstrated the safety and regenerative benefits of mesenchymal stem cell in bone and soft tissue reconstruction. Adipose-derived stem cell and dental pulp stem cell showed favorable outcomes in angiogenesis and healing, while bone marrow’s cell proved effective in bone regeneration, particularly when combined with scaffolds. Discussion and Conclusions Although results are promising, limitations remain in consistency and long-term outcomes. Optimizing scaffold integration, preservation methods, and delivery techniques is crucial. Mesenchymal stem cell-based therapies represent a powerful, minimally invasive alternative to traditional grafting in oral and maxillofacial surgery.
