Abstract Objective: To analyze the clinical application of Bio-Oss bone powder combined with concentrated growth factor (CGF) in simultaneous implantation of maxillary sinus elevations in patients with bone deficiency in maxillary posterior teeth area. Method: A total of 80 patients with bone deficiency in the posterior maxilla who were admitted to the Department of Stomatology, Shangrao People's Hospital from January 2019 to December 2020 were selected, and divided into the control group (n=34) and the combination group (n=46) according to the suitable implanted bone substitute material chosen based on the patient's condition. The control group underwent Bio-Oss bone powder implantation, while the combination group underwent Bio-Oss bone powder combined with CGF implantation. The bone mineral density in the implantation area, bone tissue height around the implant and implant stability quotient (ISQ values) were compared between the groups. Result: The bone mineral density in the implantation area of the combination group were significantly higher than those in the control group at 6, 12 and 18 months after operation (P<0.05). Bone tissue height around the implant in the combination group were significantly smaller than those in the control group at 6, 12 and 18 months after operation (P<0.05); ISQ values were significantly higher than those in the control group at 6, 12 and 18 months after operation (P<0.05). Conclusion: Applying Bio-Oss bone powder combined with CGF in simultaneous implantation of maxillary sinus elevations in patients with bone deficiency in maxillary posterior teeth area can effectively improve the bone mineral density in implantation area and help to improve osteogenesis effect around the implant, with good safety.
