The objective was to test the influence of a pulsed electromagnetic field (PEMF) on bacterial biofilm colonization around implants incorporated with healing abutments. Healing abutments with (test group) and without (control group) active PEMF devices were placed in a multispecies biofilm consisting of 31 different bacterial species. The biofilm composition and total bacterial counts (x10) were analyzed by checkerboard DNA-DNA hybridization. After 96 h, the mean level of 7 out of the 31 bacterial species differed significantly between groups, namely ssp. nucleatum ssp. Vicentii and were elevated in the control group ( < 0.05). The mean total bacterial counts were lower in the Test group the control group ( < 0.05). An electromagnetic healing cap had antimicrobial effects on the bacterial species and can be used to control bacterial colonization around dental implants. Further clinical studies should be conducted to confirm these findings.
目的是测试脉冲电磁场 (PEMF) 对带有愈合基台的植入物周围细菌生物膜定植的影响。带有（实验组）和不带有（对照组）主动 PEMF 装置的愈合基台被放置在由 31 种不同细菌组成的多物种生物膜中。通过棋盘 DNA-DNA 杂交分析生物膜组成和总细菌计数（x10）。96 小时后，7 种细菌的平均水平在组间有显著差异，即 ssp. 核梭杆菌 ssp. Vicentii 和 在对照组中升高（<0.05）。实验组的总细菌计数 对照组（<0.05）。电磁愈合帽对细菌具有抗菌作用，可用于控制牙种植体周围的细菌定植。应进行进一步的临床研究以证实这些发现。
