Abstract

Abstract: PURPOSE: To investigate the effect of autologous concentrated growth factor fibrin solution combined with Bio-Oss bone powder on mucosal healing and bone regeneration after oral implanted guided bone regeneration. METHODS: From October 2016 to December 2018, 83 patients with maxillary single anterior tooth loss and labial bone defect were treated, they were divided into two groups. Patients in the experimental group (42 cases) received autologous concentrated growth factor fibrin solution + Bio-Oss bone powder, while patients in the control group (41 cases) received Bio-Oss bone powder alone. The degree of mucosal healing, implant success, bone defect regeneration, pain and other complications were followed up 7 days, 6 weeks and 1 year after operation. The success rate and complications of the two groups were observed, as well as the differences of mucosal color, swelling degree, bleeding index, depth of probing, attachment loss, height of bone graft and thickness of bone formation were measured and recorded. Statistical analysis was performed using SPSS 25.0 software package. RESULTS: There was no significant difference in the success rate of implants between the two groups (95.24% vs 97.56%, P>0.05). The complication rate of the experimental group was significantly lower than that of the control group (2.38% vs 14.63%, P<0.05). The mucosal color and swelling degree scores of the experimental group were significantly lower than those of the control group [(0.65±0.03) points vs (2.01±0.15) points, (1.10±0.37) points vs (2.69±0.54) points, P<0.05], and the bleeding index, probing depth, and attachment loss were significantly lower than the control group [(0.35±0.05) vs (0.49±0.09), (3.39±0.62) mm vs (4.41±0.95) mm, (3.02±0.66) mm vs (5.31±0.91) mm, P<0.05], bone graft height and osteogenesis height were significantly higher than the control group [(2.61±0.50) mm vs (2.20±0.31) mm, (2.53±0.34) mm vs (2.02±0.27) mm, P<0.05]. The degree of postoperative pain in the experimental group was significantly lower than that in the control group(P<0.05). CONCLUSIONS: Rich self-concentrating growth factor fibrin solution combined with Bio-Oss bone powder can effectively promote mucosal healing and bone regeneration after oral implant-guided bone regeneration, and reduce postoperative pain and complications.
