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: Choukroun’s platelet fibrin membrane (PRF membrane) surgery for the treatment of gingival recession, the clinical effect of treatment before and after evaluation. Methods: Ten cases of Miller Ⅰ ~ Ⅱ degree patients who had gingival recession and who were willing to undergo PRF were selected. PRF was used to measure periodontal disease at preoperative and postoperative time points (3, 6 and 12 months after operation) Bag depth, gingiva width, attachment loss, compared with the clinical effect before and after treatment. Results: The depth of periodontal pouch had no significant difference before and after operation (P> 0.05). The width of keratinized gingival margin increased significantly (P <0.05) All coverage, preoperative and postoperative groups were significantly different (P <0.05). Conclusion: PRF membrane (platelet-rich fibrin) treatment of gingival recession Miller Ⅰ, Ⅱ degree cases can achieve good clinical effect.
