目的：研究浓缩生长因子（CGF)在即刻种植修复牙龈愈合中的临床效果。方法：20例即刻种植修复患者分为两组，实验组在种植体-骨间隙内添加CGF与Bio-oss骨粉混合物，比例为1：1，对照组种植体-骨间隙内单独添加Bio-oss骨粉，从术后牙龈愈合情况，牙间乳头指数及牙龈缘高度3个方面评价CGF对牙龈组织愈合的影响。结果：术后10天内，实验组牙龈组织愈合明显好于对照组；术后6个月时所有病例为3度牙间乳头；实验组牙龈退缩为（0.35±0.15）mm，对照组牙龈退缩为（0.42±0.37）mm，两者间没有统计学意义（＞0.05）。结论：浓缩生长因子（CGF）具有促进牙龈组织愈合的作用。

Objective To study the clinical gingival healing effect of concentrated growth factor (CGF) used in immediate implant and immediate restoration. Methods 20 patients were divided into two groups of immediate implant and immediate restoration, the 1:1 ratio of CGF and Bio- oss mixture was added to the implant- bone gap in 10 cases;Bio- oss was placed alone to the implant- bone in the other 10 cases,evaluate the clinical impact of CGF from gingival tissue healing and nipple height index and the gingival margin. Results In 10 days postoperative,the gingival tissue healing of CGF groups was significantly better than the control group; all cases was 3 degrees dental papilla in 6months after implantation; CGF group gingival recession was (0.35±0.15)mm and the control group gingival recession was 0.42±0.37 ( P>0.05). Conclusion The concentrated growth factor (CGF) can promote gingival tissue healing.
