DENTAL COMPONENT, DENTAL IMPLANTABLE COMPONENT AND DENTAL IMPLANT Russian patent published in 2017 - IPC A61C8/00 

FIELD: medicine.

SUBSTANCE: group of inventions includes dental component, dental implant and dental implantable component, refers to the field of dentistry, namely to dental implantology and intended for replacement of a missing tooth. The dental component comprises an implantable component engaging portion for dental component engagement with the dental implantable component adapted to be inserted in the jaw bone, or for dental component engagement with a modeled implantable component. The implantable component engaging portion has a geometric central axis and is provided with at least one radially projecting first indicating element with an apical end, and at least one radially projecting second indicating element. The second indicating element has an apical end located further towards the top end of the apex of the said first indicating element. The region of the second indicating element apical end, which is the most distant in radial direction, is located at a smaller radial distance from the said central axis than the region of the first indicating element apical end, which the most distant in radial direction, and/or of the second indicating element apical end is smaller compared with the first indicating element apical end along the perimeter of the engaging portion of the implantable component. At least one first indicating element is separated along the perimeter from any of the said (at least one) second indicating elements. At least one second indicating element is the only second indicating element or at least two second indicating elements asymmetrically distributed along the perimeter of the engaging portion of the implantable component.

EFFECT: invention allows the dentist to provide easier determination of the desired angular orientation of the dental component, such as an abutment relative to the implantable component through the use of at least two indicating elements for accurate engagement of abutment protrusions with recesses in the implanted component, and to provide additional anti-rotation capability.
