富血小板纤维蛋白膜(PRF)治疗牙龈退缩的临床效果评价

To evaluate the clinical effects of PRF(Platelet-Rich-Fibrin) membranes in gingival recessions

目的：采用Choukroun＇s富血小板纤维蛋白膜（PRF膜）手术治疗牙龈退缩,对治疗前后的临床效果进行评价。方法：选取有牙龈退缩且有意愿进行PRF手术治疗的MillerⅠ～Ⅱ度患者10例,采用PRF手术,在术前、术后不同时间点（术后3、6、12个月）分别测量牙周袋深度、附着龈宽度、附着丧失,对比治疗前后的临床效果。结果：牙周袋深度术前术后无显著性差异（P〉0.05）;角化龈宽度增加,术前与术后各组之间有显著性差异（P〈0.05）;根面达到部分或全部覆盖,术前与术后各组之间有显著性差异（P〈0.05）。结论：PRF膜（富血小板纤维蛋白）治疗牙龈退缩MillerⅠ、Ⅱ度病例可以达到很好的临床治疗效果。

Objective： To explore the new ways of clinical treatment of gingival Recessions through Clinical Evalua- tion of Choukroun＇s platelet-Rich-Fibrin （PRF） Membranes. Method： Choose 10 patients of Gingival Recessions intend to surgical treatment, measure periodontal pocket depth, width of attached gingival and loss of attachment level in different time points of preoperative and postoperative （after 2 months, 3 months, 6 months, 1 year）,TO contrast the Clinical effect of the Clinical Evaluation of Choukroun＇s PRF Membranes in Gingival Recessions, Provide theoretical basis for clinic. Result.. No significant change in Periodontal pocket depth by surgery （P 〉0.05） ; The width keratinized gingival is increasing, A signifi- cant change in it after operation as compared with every group before operation （P 〈0.05） ; To cover part or all of root sur- face, A significant change after operation as compared with every group before operation （P 〈0.05）. Conclusion： For gingival Recessions, It can be achieved a better Clinical effects by Platelet-Rich-Fibrin （PRF） Membranes.
