Abstract：Objective To evaluate the clinical efficacy of Bio-Oss bone powder combined with concentrated growth factor(CGF)in repairing bone defects in autogenous tooth transplantation.Methods A total of 44 patients trea-ted in the Department of Oral Surgery at Hefei Stomatological Hospital from July 2018 to June 2022 were selected.The ob-servation group consisted of 23 patients who received Bio-Oss bone powder and CGF during surgery,while the control group consisted of 21 patients who did not receive any material.Patients were followed up regularly postoperatively.The immediate stability after tooth transplantation,gingival condition one week postoperatively,bone healing at three and six months postoperatively,and the success rate one year postoperatively were compared between the two groups.Results The immediate stability after tooth transplantation was significantly improved in the observation group compared to the con-trol group,with a statistically significant difference(P＜0.05).There was no significant improvement in gingival swelling one week postoperatively between the two groups(P＞0.05).Bone healing at three months postoperatively was better in the observation group than in the control group,with a statistically significant difference(P＜0.05).At one year follow-up,the success rate of tooth transplantation was 100％in the observation group and 90.5％in the control group,with a retention rate of 95.2％and a failure rate of 4.8％.The difference was statistically significant(P＜0.05).Conclusion Bio-Oss bone powder combined with CGF has good clinical efficacy in repairing bone defects in autogenous tooth trans-plantation.It promotes new bone formation,facilitates early stability of the transplanted tooth,and improves the success rate of autogenous tooth transplantation.
