Abstract: L'invention concerne un implant dentaire contenant une intercouche de polyéther-éther-cétone (3) et son procédé de fabrication. L'implant dentaire comprend une pile externe (1), une pile interne (2) et une intercouche de polyéther-éther-cétone (3). La pile externe (1) et la pile interne (2) sont toutes les deux des corps tournants standard. Un trou borgne (4) est formé dans la pile externe (1). La pile interne (2) comprend une table cylindrique (5) et une tige de liaison (6) perpendiculaire à la face d'extrémité de la table cylindrique (5). L'intercouche de polyéther-éther-cétone (3) est disposée de manière fixe dans le trou borgne (4) et pourvue d'un filetage interne correspondant à la tige de liaison (6). La pile interne (2) est reliée par filetage à l'intercouche de polyéther-éther-cétone (3) au moyen de la tige de liaison (6). L'implant dentaire contenant l'intercouche de polyéther-éther-cétone (3) réduit le module d'élasticité global de l'implant dentaire par ajout de l'intercouche de polyéther-éther-cétone (3). L'implant dentaire endommagé peut être démonté et remplacé de manière commode au moyen d'une conception structurelle multicouche, et les dommages sont réduits ainsi, en particulier lorsqu'une vis centrale est toujours hors du travail. De plus, la conception structurelle multicouche est avantageuse pour la réutilisation de parties intactes.
