摘要
目的:通过对比观察采用Choukroun's富血小板纤维蛋白膜(PRF膜)和采用结缔组织瓣治疗牙龈退缩的临床效果。方法:临床上选取有牙龈退缩且有意愿进行手术治疗的患者13例,分为PRF膜组和对照组,分别实施手术治疗,在术前、术后3个月测量牙周袋深度(PD)、角化龈宽度(KTW)以及牙龈退缩量,并对结果进行对照分析。结果:两组数据中牙周袋深度术前术后比较均无显著性差异(P≤0.05);角化龈宽度和牙龈退缩量术前术后比较均有显著性差异(P≥0.05)。角化龈宽度术后比较两组之间无显著性差异(P≥0.05);牙龈退缩量对照组小于PRF组(P≤0.05)。结论:PRF膜(富血小板纤维蛋白)治疗牙龈退缩的根面覆盖量虽不及结缔组织瓣+冠向复位组,但对于MillerⅠ°、Ⅱ°同样可以达到很好的根面覆盖效果;且术后角化龈宽度明显增加,和膜龈组之间无显著性差异(P>0.05)。
Objective：To provide the Clinical evaluation of Choukroun＇s platelet-Rich-Fibrin（PRF） Membranes in treatment of gingival recessions contrasting connective tissue graft. Method：Choose 13 patients of Gingival Recessions intend to surgical treatment, measure periodontal pocket depth, width of attached gingival and loss of attachment level in preoperative and postoperative 3 months. TO contrast the Clinical effect of Choukroun＇s PRF Membranes in Gingival Recessions. Result：It has no statistically significant change in Periodontal pocket depth by surgery for both groups（P〉0.05）;The width keratinized gingival and vertical gingival recession depth are increasing after operation, have statistically significant changes compared with pre-operation（P〈0.05）.It has no statistically significant change after operation between groups for width keratinized gingival（P〉0.05）;It was fewer for the PRF group in comparison with the control group for vertical gingival recession depth（P〈0.05）.Conclusion：For root coverage, it can be achieved a better clinical effects by Platelet-Rich-Fibrin（PRF） membranes,especially for Miller ClassⅠorⅡ.
