Titanium-prepared platelet-rich fibrin (T-PRF) is activated with titanium, which results in a more mature and aggregated form than PRF. In our previous studies, we established that the fibrin carpet formed with titanium had a firmer network structure, and longer resorption time in the tissue than the fibrin carpet formed with glass. The purpose of this randomized controlled clinical trial is to compare the effects of autogenous T-PRF and connective tissue graft (CTG).
A total of 114 Miller Class I/II gingival recessions with abrasion defects were treated either T-PRF (63 teeth) or CTG (51 teeth) using a modified tunnel technique. Clinical periodontal indexes, keratinized tissue (KTW), gingival thickness, and recession depth were recorded before surgery and at 6- and 12-month follow-up examinations. The visual analog scale and healing index scores were assessed.
The mean root coverages were 93.29 and 93.22% in the T-PRF and CTG groups, respectively, at 12 months post-operatively. CTG resulted in greater gingival thickness than T-PRF at 6 and 12 months post-surgery compared to baseline. Furthermore, the mean amounts of KTW increased by 1.97 and 0.75 mm in the T-PRF and CTG groups, respectively.
Within the limits of this study, the results demonstrated that T-PRF is safe and effective for treatment of multiple Miller Class I/II gingival recession defects.
T-PRF can serve as a good autogenous alternative to CTG, which is the gold standard for root coverage.
钛制备富血小板纤维蛋白(T-PRF)通过钛激活,这导致比 PRF 更成熟和更聚集的形式。在我们之前的研究中,我们发现用钛形成的纤维蛋白毯具有更坚固的网络结构,并且在组织中的吸收时间比用玻璃形成的纤维蛋白毯更长。本随机对照临床试验的目的是比较自体 T-PRF 和结缔组织移植物(CTG)的效果。
共治疗 114 例 Miller 类 I/II 牙龈退缩伴磨损缺损,使用改良隧道技术分别用 T-PRF(63 颗牙)或 CTG(51 颗牙)处理。记录术前、术后 6 个月和 12 个月的临床牙周指数、角化组织(KTW)、牙龈厚度和退缩深度。评估视觉模拟量表和愈合指数评分。
术后 12 个月,T-PRF 和 CTG 组的平均根覆盖率分别为 93.29%和 93.22%。与基线相比,术后 6 个月和 12 个月,CTG 组的牙龈厚度均大于 T-PRF 组。此外,T-PRF 和 CTG 组的 KTW 平均增加量分别为 1.97mm 和 0.75mm。
在本研究范围内,结果表明 T-PRF 治疗多个 Miller 类 I/II 牙龈退缩缺损是安全有效的。
T-PRF 可以作为 CTG 的良好自体替代物,CTG 是根覆盖的金标准。
