A dental implant is provided that can be firmly fixed in an oral cavity, even if the amount of bone required to embed the implant is small. A necessary amount of bone can be provided by generating new bone so that the fixture part of the implant can be fixed in the bone. The fixture part of the implant includes several members which are movably connected to each other so that the fixture part is adjustable in length. The fixture part includes a first member which is made up of an uppermost member, a middle member, and an end member. It is preferred that the middle member be cylindrical or rod-shaped with male screws extending radially-outwardly from an outer circumferential periphery thereof. The fixture part also includes a second member which is a hollow cylinder. It is preferred that the hollow cylinder have a tapped hole on one end with female screw on an inner periphery thereof so that the middle member of the first member can be screwed into the second member. A continuous stimulating force which is formed by the embedment of the implant into bone and the lifting up of the mucous membrane by extending the fixture part of the implant, contributes to the osteogenesis around the implant
Implant dentaire qu'on peut fixer fermement à l'os dans la cavité orale, même quand l'os manque de la quantité nécessaire à l'implantation, au moyen de la constitution de nouveaux os, ce qui permet de disposer de ladite quantité. Ce dispositif comprend une combinaison de plusieurs éléments présentant des longueurs librement réglables. Plus particulièrement, on préfère un ensemble composé d'un élément extérieur tubulaire pourvu d'un taraudage, dans lequel est vissé, de façon à être solidaire de l'ensemble, un élément intérieur en forme de tige filetée. On constitue de nouveaux os autour de l'implant par stimulation continue de la membrane muqueuse au moyen de l'insertion de l'implant dans l'os et du soulèvement de la membrane par élongation des éléments.
