Abstract
After loss of teeth in the posterior maxilla, the alveolar ridge decreases by bone atrophy and pneumatization of the maxillary sinus cavity. Maxillary sinus augmentation is a well-established technique for functional rehabilitation of partially or completely edentulous patients with severe maxillary atrophy and the goal of sinus augmentation procedures is to create bone quantity and quality in order to ensure the placement of dental implants of sufficient length and satisfying initial stability. Various bone grafting materials have been used in sinus augmentation including autogenous graft, freeze-dried bone allograft, xenograft, and alloplastic material. Attempts have been made to increase the bone formation using growth factors, such as bone morphogenetic proteins (BMPs). Platelet-rich plasma (PRP) has been used in sinus augmentation procedures but conflicting results are being reported. Tissue engineering procedure using autogeous mesenchymal stem cells combined with scaffold has been applied in maxillary sinus augmentation procedure. In this review, the effect and efficacy of biomaterials including growth factors and mesenchymal stem cells in sinus augmentation procedures will be addressed.
