摘要： The invention relates to an intra-osseous implant for placement in bone of a human or animal body comprising at least

one intra-osseous part (12) intended for placement in said bone tissue having an apical side (12b) and a cervical side (12c) and composed of a body friendly material, which part is provided on its circumferential surface with a thread (18) running in the direction of the apical end; and
a support part (15) present at said cervical side of said at least one intra-osseous part intended for supporting a prosthetic element.

The invention aims to provide a medical intra-osseous implant and especially a dental intra-osseous implant, which allows an accurate implant position at a desired depth into bone tissue, without losing a high degree of primary implant stability.
To this end according to the invention the intra-osseous part is provided with one or more grooves (19a-c) extending in longitudinal direction and interrupting the screw thread.

摘要： A single stage dental implant for implantation in living jawbone having overlying gingiva comprises a generally cylindrical body section having an exterior surface for confronting the jawbone and a head section attached to the body section for extending through the overlying gingiva when the body section is confronting the jawbone. The head section has an end portion which is generally near an outer layer of the gingiva. The implant further includes a bore within the head section extending to an opening at the end portion of the head section. The bore is defined by first, second, and third walls. The first wall has internal threads. The second wall has a larger diameter than the first surface and is substantially cylindrical. The second wall extends from the first wall toward the end portion. The third wall extends from the second wall to the opening and flares toward the opening to a diameter that is wider than a diameter of the second wall. The implant is delivered to the site in the patient's mouth with a carrier that is expanded into the second wall of the bore thereby developing a tight engagement capable of withstanding the insertion torque. The implant can be fitted with posts which extend above the upper portion of the implant. The post can be fitted with gingival forming components and temporary posts.
