Development of the objective diagnostic method using the specific serum antibody titer on peri-implantitis.

本研究对16名受试者的20个种植体进行。X线片显示骨缺损大于2mm的种植体周围炎9例。在牙周致病菌的检测中，虽然与种植体周围炎无关，但高频率检测到了T. pylori，并对9名受试者的11颗种植体（7颗种植体周围炎）和9颗天然牙进行了微生物组分析。结果表明，在牙周病和种植体周围炎中，G.碱性杆菌、G.盐单胞菌、G.密螺旋体和G.酸性氨基球菌的检出率较高。尤其是G. Acidaminococcus在种植体周围炎中明显升高。

This study was performed on 20 implants of 16 subjects. The number of the implant with peri-implantitis which have the bone defect more than 2mm on X-ray photograph was nine. In the examination of periodontopathic bacteria, it is not concerned with the peri-implantitis, but T.forsythesis was detected by high frequency.Furthermore, microbiome analysis was conducted for 11 implants (7 peri-implantitis) of nine subjects, and nine natural teeth. As a result, with periodontosis and peri-implantitis, the rate of G.Alkalibacterium, G.Halomonas, G.Treponema, and G.Acidaminococcus is high. Especially G.Acidaminococcus is notably high with the peri-implantitis.
