The aim of this randomized controlled trial was to assess the effect of two maintenance programmes when treatments were performed every third month from six to 18 months following surgical treatment of peri-implantitis.
At the 6-month post-surgical evaluation, 44 subjects were randomized into groups receiving supportive peri-implant treatment either by the use of titanium curettes or chitosan brushes at implants registered with BoP and PPD >3 mm. Follow-up examinations and supportive therapy were performed 6, 9, 12, 15 and 18 months post-surgically. Clinical and radiographic assessments were made.
The percentage of implants registered with inflammation was high at the 6-month baseline examination (>80% bleeding on probing in both test and control group) and remained high throughout the observation period. Similar observations were made for all clinical parameters, and no significant difference was found between test and control groups.
In the present study, no statistical significant difference was found when supportive peri-implant treatment was performed with either titanium curettes or chitosan brushes. Within the limits of the study, the results might indicate the need of more effective submucosal cleaning procedures following peri-implant surgery.
本随机对照试验旨在评估在种植体周围炎治疗后 6 至 18 个月，每 3 个月进行一次治疗时，两种维护方案的效果。
在术后 6 个月评估时，将 44 名受试者随机分为两组，分别使用钛刮治器或壳聚糖刷对探诊出血（BOP）和探诊深度（PPD）>3mm 的种植体进行支持性种植体治疗。术后 6、9、12、15 和 18 个月进行随访检查和支持性治疗。进行临床和影像学评估。
在 6 个月的基线检查中，有炎症的种植体百分比很高（>80%的探诊出血，试验组和对照组均如此），并在整个观察期间保持较高水平。所有临床参数均观察到类似情况，试验组和对照组之间无显著差异。
在本研究中，当使用钛刮治器或壳聚糖刷进行支持性种植体治疗时，未发现统计学显著差异。在研究范围内，结果可能表明需要在种植体周围手术后采用更有效的黏膜下清洁程序。
