【摘要】 目的 观察浓缩生长因子（CGF）在复杂牙拔除后牙槽窝处理中的应用效果。方法 90例接受复杂牙拔除的患者随机分为两组，观察组采用CGF处理牙槽窝，对照组采用牙槽窝常规处理，比较两组的牙槽嵴宽度和高度、牙槽嵴骨量。结果 术后30 d、 90 d，观察组的牙槽嵴宽度、高度均高于同期对照组（P <0.05）。术后90 d，两组的REC均升高，且观察组的REC高于对照组（P <0.05）。结论 CGF用于复杂牙拔除后牙槽窝的处理可有效维持牙槽嵴的高度及宽度，防止拔牙后牙槽骨吸收。更多还原

【Abstract】 Objective To explore the application effect of concentrated growth factor(CGF) in the treatment of alveolar socket after complex tooth extraction. Methods A total of 90 patients with complex tooth extraction were randomly divided into two groups. The observation group used CGF to treat the alveolar socket, and the control group received conventional alveolar socket treatment. The width and height of alveolar ridge, and the bone mass of alveolar ridge were compared between the two groups. Results At 30 d and 90 d after surgery, the width and height of alveolar ridge in the observation group were higher than those in the control group at the same period(P <0.05).At 90 d after surgery, REC in both groups increased, and REC in the observation group was higher than that in the control group(P <0.05).Conclusions The application of CGF in the treatment of alveolar socket after complex tooth extraction can effectively maintain the height and width of alveolar ridge, and prevent alveolar bone resorption after tooth extraction.更多还原
