DENTAL ENDOSTEAL-SUBPERIOSTEAL IMPLANT AND METHOD FOR PLACING IT Russian patent published in 2014 - IPC A61C8/00 C22C19/03 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely to surgical dentistry, and is applicable as a bridge prosthesis carrier in the patients suffering a maxillary lateral alveolar process defect. The dental endosseous-subperiosteal implant is made of a thermally mechanical shape-memory material and configured as a solid structure comprising an intraosseous plate with one or more abutment, with one or more vestibular osseous throw-over tape and with one or more palatal osseous throw-over tape. The vestibular and palatal osseous throw-over tapes with a semicircular section and a flattened surface facing inside, are curbed after the alveolar process shape, uniformly distributed alongside and from both sides of the intraosseous plate, gradually taper to a free end bent with its hook inside. The intraosseous plate has active elements at the ends. A height of the figure-of-eight active element is 1.5-2 times higher than that of the intraosseous plate and comprises an open ring with a horizontal connector and an open ellipse with a vertical connector. Arches of the open ring and open ellipse at the level of the connector are oppositely separated. From the opposite end, the intraosseous plate has either the ring-shaped active element with the oppositely separated arches at the level of the horizontal connector, or the rectangular active element consisting of two legs oppositely separated in the horizontal plane. An analogue implant comprising a plate with rectangular projections in a projection of the throw-over tapes is used to form a slot for the intraosseous plate of the endosseous-subperiosteal implant in the alveolar process along its crest. kgrooves with an intraosseous canal at the end are formed across the crest along slopes for placing the osseous throw-over tapes at 0 to +5°C. The osseous throw-over tapes are separated by means of crampon forceps, and a hook is folded to 90°. The active elements are aligned within a single contour with the intraosseous plate. The implant is placed intraosseously and osseously into the prepared slot, groove and canal.

EFFECT: by opposite three-plane separation of the active elements of the intraosseous plate of the implant, bone in-growth into the through holes of the active elements inside the osseous plate, the group of inventions enables providing higher stabilising properties of the dental endosseous-subperiosteal implant and improving the functional qualities of the prosthetic implant system.
