ʌAbstractɔObjective:To study the application value of concentrated growth factor(CGF)and Biooss bone substitute materials in mandibular implants.Methods:A total of101patients with immediate implant bone loss in mandibular posterior area in our hospital from June2019to June2022were retrospectively select-ed,and the patients were grouped according to differences in treatment regimen:51in observatio
n group and 50in control group,The control group was treated with the Biooss bone substitute material,the observation group was given concentrated growth factors on the basis of the control group.The patients were followed up by telephone and outpatient clinic6months after the treatment to compare the horizontal and vertical bone graft-ing,bone thickness and bone regeneration effects between the two groups;the clinical efficacy of the patients was evaluated according to the changes in the postoperative stability coefficients(ISQ),and the levels of bone thickness,bone density,and bone width were compared between the two groups at the immediate postoperative stage,at3months after the surgery and at6months after the surgery;and the patients were compared with re-spect to the degree of recovery of the postoperative masticatory function,the height of gingival papilla attach-ment and overall dental esthetic degree index measurements.The measured values of the patients'postopera-tive masticatory function recovery,gingival papilla attachment height,and overall dental esthetics were com-pared.At the end of the follow-up period,patients'satisfaction with the treatment was collected and the differences between groups were compared.Results:The effect of bone regeneration in the horizontal and ver-tical directions(94.00%,92.00%)was better than that of the control group(90.19%,86.27%).The ISQ mean of patients in control group decreased first and then increased,with the lowest ISQ score of the patients, and the ISQ mean of observation group showed an increasing trend.The ISQ mean was different between both groups at1week and4weeks after the o
peration,and the mean of observation group was higher than that of control group(P<0.05),but the difference between the immediate postoperative and8weeks was not signifi-cant(P>0.05).The immediate bone thickness,bone width and bone density values in the two groups were comparable(P>0.05);compared3and6months after surgery,and observation group was higher than ser-ums(P<0.05).Compared with serums,the recovery degree of masticatory function,the height of the whole gingival nipple increased,with a statistically significant difference(P<0.05).The treatment satisfaction of observers was(96.00%)was higher than that of serums(84.31%),(P<0.05).Conclusion:Concentrate growth factor(CGF)and Biooss bone replacement material can improve patient satisfaction and bone regenera-tion effect,maintain the stability of postoperative implant,and have good clinical application effect.
