IMPLANT OVERDENTURE SYSTEM AND IMPLANT

摘要

An implant over denture system (1) fixes an implant over denture (3) to a residual ridge (8) by means of an implant (10). The implant over denture (3) has a prosthetic tooth (31), a denture baseplate (32), and a magnet structure (4). The implant (10) has an implant main body section (11) and a keeper (2). The maximum diameter (d1) of the circumscribed circle of the external shape of the adsorbed surface of the keeper (2) is set to be at least ? 1.8 mm and the maximum diameter (d2) of the implant main body section (11) is set to be at least ? 1.2 mm and no more than ? 3.5 mm, so that the two diameters have a relationship of d1/d2= 1.5.
