Application effects of platelet-rich fibrin combined with bone filling material in maxillary sinus lifting
Objective:To observe application effects of platelet-rich fibrin(PRF)combined with bone filling materials in maxillary sinus lifting.Methods:A prospective study was conducted on 110 patients who underwent maxillary sinus lifting in this hospital from March 2021 to March 2023.According to the random number table method,they were divided into control group and observation group,55 cases in each group.The control group was implanted with bone filling materials,while the observation group was combined with PRF implantation on the basis of that of the control group.The postoperative pain[visual analogue scale(VAS)]score,the implant stability coefficient(ISQ)value,the new bone height,the incidence of complications,and the implant retention rate were compared between the two groups.Results:12 and 24 hours after the surgery,the VAS scores of the observation group were lower than those of the control group,and the differences were statistically significant(P<0.05).3 and 6 months after the surgery,the ISQ values of the observation group were higher than those of the control group,and the differences were statistically significant(P<0.05).6 months after the surgery,the height of proximal and distal new bone in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05).The incidence of complications in the observation group was 1.82%(1/55),which was lower than 16.36%(9/55)in the control group,and the difference was statistically significant(P<0.05).However,there was no significant difference in implant survival rate between the two groups(P>0.05).Conclusions:PRF combined with bone filling materials in maxillary sinus lifting can reduce the postoperative pain scores and the incidence of complications,and improve the postoperative ISQ value and the new bone height.Moreover,it is superior to simple bone filling material.
