<p>The improvement of the present invention pertains to a frustoconical abutment (20 and 20') intended to overcome the problem of the implant's (I) lack of parallelism. The abutment (20 and 20') can be of the Allen-driven type or the through-screw type. Both engage with an implant (I) ranging from partially to totally inserted below the gingival margin. The abutment (20 and 20') of the Allen-driven type includes a threaded cavity (22) that receives a threaded member (M) of a prosthesis (P). The through-screw abutment (20 and 20') includes a threaded through-opening that also receives the threaded member (M) of a prosthesis (P). The frustoconical abutment (20 and 20') permits a dentist to reduce the mass to end up with a resulting shape that will correct the lack of parallelism typically created by misaligned implants (I) and allowing for more aesthetic form which mimics a natural tooth shape. This is particularly helpful when part of the implant's (I) end protrudes from the gingival margin instead of submerged below it.</p> |
