Dental jaw implant to affix dentures

摘要

A dental jaw implant for supporting at least one of a replacement tooth neck and a crown portion includes a monolithic implant body comprising an ingrowth section comprising an ingrowth structure which grows together with a patient's jaw bone. An insertion opening is arranged at a coronal axial end. A replacement tooth neck and/or a crown portion is inserted in the insertion opening. A female thread adjoins the insertion opening. The female thread threads a replacement tooth retaining element. The replacement tooth retaining element retains the at least one of the replacement tooth neck and the crown portion. An outer cone is arranged at the coronal axial end. The outer cone tapers towards a non-coronal end. A radial step comprises an annular surface substantially disposed in a radial plane. The annular surface is arranged between the outer cone and the ingrowth section.

主权项

1. A dental jaw implant for supporting at least one of a replacement tooth neck and a crown portion, the dental jaw implant consisting of a monolithic implant body consisting of an ingrowth section and an outer cone:
the ingrowth section comprising an ingrowth structure configured to grow together with a patient's jaw bone; the ingrowth section having a top surface at a coronal end of the ingrowth section and a non-coronal end defining a non-coronal, terminal end of the implant; the outer cone extending directly from the top surface of the ingrowth section in a coronal direction and having a top surface defining a coronal, terminal end of the implant; the outer cone tapering from a wide end at the coronal end of the implant to a narrow end making direct contact with the top surface of the ingrowth section, the wide end being wider than the narrow end; an insertion opening arranged at the coronal end of the implant, the insertion opening being configured to have the at least one of the replacement tooth neck and the crown portion be inserted therein; and a female thread adjoining the insertion opening, the female thread being configured to thread a replacement tooth retaining element, the replacement tooth retaining element being configured to retain the at least one of the replacement tooth neck and the crown portion, wherein, the top surface of the ingrowth section forms a radial step consisting of one annular surface substantially disposed in a radial plane, the one annular surface being arranged directly between the narrow end of the outer cone and the ingrowth section and facing the coronal end of the implant.
