Abstract

L'invention concerne un implant dentaire (1) réalisé partiellement ou entièrement en polyétheréthercétone. Selon l'invention, une première partie de surface (34, 35, 36, 37, 38) d'une zone de l'implant dentaire (34', 35', 36', 37', 38') dont le matériau d'implant est constitué de polyétheréthercétone ou comporte au moins de la polyétheréthercétone, et au moins une deuxième partie de surface (34, 35, 36, 37, 38) d'une zone de l'implant dentaire (34', 35', 36', 37', 38') dont le matériau d'implant est constitué de polyétheréthercétone ou comporte au moins de la polyétheréthercétone, sont préparées chacune au moyen d'une action mécanique et/ou physique et/ou chimique telle que la surface que l'on obtient suite à la préparation de ladite première partie de surface présente une capacité de rétention superficielle qui est, au moins dans certaines parties, différente de la capacité de rétention superficielle de la surface que l'on obtient suite à la préparation de ladite deuxième partie de surface et que la capacité de rétention superficielle des surfaces obtenues suite à la préparation se distingue, au moins dans certaines parties, de la capacité de rétention superficielle que la partie de surface (34, 35, 36, 37, 38) concernée présentait avant la préparation. En outre, l'invention concerne un procédé de fabrication ou de traitement d'un implant dentaire (1).
