Abstract
The invention relates to an enossal implant, which comprises a primary cylinder (10) with a central longitudenal bore (13) which can be introduced into the jawbone and is anchored therein in positive and/or non-positive manner, as well as a secondary cylinder (100) insertable into the primary cylinder (10) and which has an oscillating rod (211) inserted and held in the longitudenal bore (13) and guide tube (30) of primary cylinder (10), said rod carrying an upper modular tube (220) made from an elastic material arranged at a distance from guide tube (30), accompanied by the formation of an air gap (225) and which is constructed at its free upper end for the connection of the dental prosthesis, whereas its lower end is connected in fixed or detachable manner to the primary cylinder (10), so that an implant is obtained which not only leads to a positive and nonpositive connection to the bone and a load-free stabilization of the primary cylinder (10), but whose oscillating rod (211) absorbs the horizontal, vertical and torsional forces occuring in the mouth and diverts same into the bottom of the implant (FIG. 12).
