The optimization of biomaterials in maxillary sinus augmentation associated with bone marrow aspirate concentrate

ABSTRACT

The researches for new technologies and biomaterials are constant in Implant Dentistry field. Bone Marrow Aspirate Concentrate (BMAC) is considered an abundant source of undifferentiated mesenchymal cells. The clinical application of BMAC in association with grafts from different origins (autogenous, animal or synthetic) demonstrate to improve bone regeneration, such as, in maxillary sinus lift surgeries (MSLS). This literature review aimed to perform a strategic search for scientific articles about the use of BMAC associated with grafts in MSLS. For this, a manual search and a strategy search was carried out in three databases (Scielo, PubMed e Bireme), through crossing different descriptors as well as with search strategy "PICO" (population/procedure, intervention, comparison and outcome). According to final result, a total of 16 articles were selected for a critical and analytical analysis. The results showed a lack of randomized clinical trials about the theme, demonstrating that is still unclear about the standard clinical protocols available for association of BMAC and MSLS. It can concluded, although the scientific limitations, exists a benefic potential in BMAC approach with MSLS with different grafts, suggesting to be a therapeutic option as adjuvant for grafting materials. Therefore, there is a discreet potential profile in the acceleration of the bone neoformation process in these procedures, favoring for a posterior surgical re-intervention to dental implants placement in previously grafted areas.
