Abstract

La présente invention porte sur une prothèse médicale et sur son procédé de fabrication, et, d'une manière plus spécifique, sur une prothèse médicale ayant de fines saillies formées sur celle-ci pour empêcher un glissement et permettre une fixation ferme même lorsqu'une force externe est reçue, telle qu'un mouvement ou un choc, durant une chirurgie plastique dans laquelle une prothèse est introduite. La présente invention porte également sur un procédé de fabrication de la prothèse médicale. La présente invention peut empêcher un glissement même lorsqu'une force externe est reçue et peut être fixée fermement à un tissu ou à un squelette à travers les fines saillies ayant des sections longitudinales concaves, et peut rendre minimale l'absorption osseuse en rendant minimale la zone de contact avec le tissu.
