Clinical study of CGF combined with titanium mesh bone increment technique in bone defect implantation restoration
Objective To investigate the practical effect of concentrated growth factor(CGF)combined with titanium mesh bone increment technique in bone defect implantation restoration.Methods 60 patients with dentition defect accompanied by obvious horizontal bone mass deficiency(no obvious vertical bone mass deficiency)were divided into a control group and an observation group according to different admission time,with 30 cases in each group.The control group was implanted with conventional titanium mesh bone increment technology,and the observation group was implanted with CGF combined with titanium mesh bone increment technology.The alveolar ridge bone thickness,bone mineral density of the jaws and complications were compared between the two groups.Results Immediately after bone grafting,there was no significant difference in alveolar ridge bone thickness between the two groups(P>0.05).At 3 and 6 months after bone grafting,the alveolar ridge bone thickness in the observation group were(8.93±0.62)and(8.78±0.57)mm,which were higher than(8.38±0.60)and(8.02±0.52)mm in the control group,and the difference was statistically significant(P<0.05).Immediately after bone grafting,there was no significant difference in bone mineral density of the jaws between the two groups(P>0.05).At 3 and 6 months after bone grafting,the bone mineral density of the jaws in the observation group were(525.13±65.24)and(658.38±68.39)HU,which were higher than(456.78±58.32)and(534.67±62.25)HU in the control group,and the difference was statistically significant(P<0.05).The incidence of complications of 6.67%in the observation group was lower than 30.00%in the control group,and the difference was statistically significant(P<0.05).Conclusion CGF combined with titanium mesh bone increment technique has good effect in bone defect implantation restoration,and has clinical promotion value.
