Abstract

L'invention se rapporte au domaine de la médecine et des techniques médicales, notamment à la stomatologie chirurgicale, et peut être utilisée pour l'implantation immédiate ou précoce ou même différée en deux phases en vue du rétablissement de patients ayant perdu partiellement ou entièrement leurs dents. L'invention concerne essentiellement un implant stomatologique fileté et intra-osseux en deux étapes comprenant des parties intra-osseuse et extra-osseuse possédant entre elles une connexion conique; la partie intra-osseuse de l'implant a une forme conique; l'épaisseur du filetage du corps de la partie intra-osseuse de l'implant s'élargit à proximité du collet de la partie intra-osseuse de l'implant et la finesse du filetage diminue; la conicité du collet de l'implant est différente de la conicité du corps de l'implant; il existe une différence entre les diamètres des parties intra-osseuse et extra-osseuse de l'implant; la surface de la partie intra-osseuse de l'implant est granuleuse; et un sillon (entaille) vertical s'étant le long du filetage de la partie intra-osseuse de l'implant. Cette structure permet de réduire la vitesse de résorption des tissus osseux entourant l'implant et d'allonger la durée de vie de l'implant, d'accélérer l'intégration osseuse et la prophylaxie de ré-implant.
