Title
(EN) IMPLANT HAVING A CALCIUM PHOSPHATE COATING DEPOSITED ON A SUBSTRATE SURFACE OF THE IMPLANT WHICH HAS BEEN BLASTED WITH ALUMINIUM OXIDE PARTICLES
(FR) IMPLANT DONT LA SURFACE DE SUBSTRAT EST ENDUITE D'UN REVETEMENT DE PHOSPHATE DE CALCIUM ET NETTOYE PAR PROTECTION DE PARTICULES D'OXIDE D'ALUMINIUM
Abstract
(EN)
An implant for implantation in bone tissue has a calcium phosphate coating on a substrate surface of the implant. Prior to depositing the coating the substrate surface is blasted with particles of an aluminium oxide. The implant gives rise to a beneficial initial bone response to the implant $i(in vivo).
(FR)
L'invention concerne un implant, destiné à l'implantation dans un tissu osseux, dont une surface de substrat est revêtue d'un phosphate de calcium phosphate. Avant le revêtement, la surface de substrat est nettoyée par projection de particules d'oxyde d'aluminium. L'implant entraîne une réponse osseuse initiale bénéfique à l'implant $i(in vivo).
