22 RECHERCHE CAD/CAM Tribune Édition Française | Août/Septembre 2020 la plaque dentaire. En effet, ils ne contiennent pas qu’une seule espèce, mais sont au contraire constitués de communau- tés où plusieurs espèces différentes intera- gissent de façon complexe et répondent aux changements de l’environnement comme une seule entité (Marsh, 2004). Même si les caractéristiques d’espèces bien particulières étaient examinées séparé- ment dans la présente étude, les colonisa- teurs précoces S. sanguinis, S. oralis et S. gor- donii sont aussi importants dans la mesure où ils permettent la fixation de colonisa- teurs tardifs et, par conséquent, ils in- fluencent la composition du biofilm au cours de sa maturation. Des études ulté- rieures incluront des biofilms multiespèces plus complexes en présence de salive. 5 Conclusions Dans les limites de cette étude in vitro, on peut conclure que l’adhésion bactérienne était similaire sur le PEEK, le Ti-pc et le Ti6Al4V. Toutefois, le PEEK sablé, pourvu d’une topographie de surface plus ru- gueuse, a présenté une formation plus im- portante du biofilm par S. sanguinis, S. ora- lis, et S. gordonii.
