An additional stabilization device intended to be used in combination with an endo-osseous dental implant, such an endo-osseous implant which has at least one endo-osseous anchoring foot adapted to an installation in a jaw bone of a patient so as to cooperate with an external pillar intended to be fixed into the anchoring foot and further has means for fixing a dental prosthetic element, the anchoring foot and the pillar further has anti-rotational means with which the relative movements of the pillar relatively to the anchoring foot may be inhibited, once the pillar is placed in the anchoring foot.
