<p>The system has a tooth implant assembly (20) designed for permanent disposition in a tooth implant and comprising an elongate section (22) adapted to the tooth implant relative to its geometry. Another elongate region has geometric elements (38, 40, 42) arranged such that it is externally detected by an optical scanning device, and a reflective surface in the geometric elements to be optically scanned. An extension element has an end formed in such a manner that it is releasably connected with the latter elongate section and one of the three geometric elements.</p> |
