In vivo early plaque formation on pure titanium and ceramic abutments: a comparative microbiological and SEM analysis

摘要: A lack of information exists about the influence different implant abutment materials on bacterial colonization and its role in development perimplantar infections. In order to study these aspects, removable acrylic devices, harboring samples titanium novel ceramic abutments (Nobel Biocare) were adapted molar-premolar region 2 mandibular quadrants 4 volunteers. Samples each material collected at 6 24 h, 7 14 days. observed by scanning electron microscopy counts made means ATP detection direct plate count. The micrographs demonstrated that bacteria was already present after h presence oral cavity. After both covered several layers cells. No differences microbial between samples. microbiological analysis confirmed relevant amounts cells tested maximum achieved cavity remained constant over day period. significant two analyzed this study. addition, ATP-bioluminescence technology be a suitable system evaluate
