To evaluate an additional mechanical approach, a titanium brush, in the implant surface decontamination performed during the regenerative surgical therapy of peri-implantitis.
A randomized double-blinded clinical trial, with a 1-year follow-up, was carried out. After a hygienic phase, peri-implantitis-affected implants were randomly assigned to a control or to a test group. In the control group, implant surface was decontaminated both mechanically and chemically with 3% H O and plastic ultrasonic scalers, respectively, while in the test group, a titanium brush was also applied. Intrabony defects in both groups were filled with an alloplastic material (β-tricalcium phosphate and hydroxyapatite) and covered with a collagen membrane. The primary outcome was the reduction in probing pocket depth (PPD) at the deepest site.
Thirty patients were included, 15 in each group. At 12 months, reduction in PPD was 4.87 (standard deviation [SD] 1.55) mm and 2.85 (SD: 1.91) mm, respectively (p = 0.009). The correspondent figures for residual PPD were 3.6 (SD: 0.91) and 4.92 (SD: 1.26) mm, respectively (p = 0.007).
The additional use of a titanium brush during regenerative treatment of peri-implantitis resulted in statistically significant benefits in terms of PPD reduction after 12 months.
评估一种额外的机械方法，即钛刷，在种植体周围炎再生治疗期间对种植体表面进行的去污。
进行了一项随机、双盲的临床试验，随访时间为 1 年。在进行了卫生阶段后，将患有种植体周围炎的种植体随机分为对照组和试验组。在对照组中，分别使用 3% H2O2 和塑料超声刮治器进行机械和化学表面去污，而在试验组中，还应用了钛刷。两组的骨内缺损均用同种异体材料（β-磷酸三钙和羟基磷灰石）填充，并覆盖胶原膜。主要结局是在最深部位探测袋深度（PPD）的减少。
共纳入 30 名患者，每组 15 名。在 12 个月时，PPD 的减少分别为 4.87（标准差 [SD] 1.55）mm 和 2.85（SD：1.91）mm（p=0.009）。相应的残留 PPD 分别为 3.6（SD：0.91）mm 和 4.92（SD：1.26）mm（p=0.007）。
在种植体周围炎的再生治疗中额外使用钛刷，在 12 个月时在 PPD 减少方面具有统计学显著益处。
