Timplant ® (b) [53].

The certiied system of Timplant ® manufactured according to
standard EN ISO 13485:2003 was used during the development of
the Nanoimplant ® implant. The intraosseal nanoimplant of 2.4 mm
diameter 2.4 mm has the strength equivalent to the conventional
of 3.5 mm diameter implant. A number of over 250 Nanoimplants ®
have been implanted [41]. For example, a 55-year-old male with
edentulous mandible and maxilla was treated by insertion of conical
implants laterally and Nanoimplants ® in the narrow anterior
part (Fig. 13.4). Primary retention of all implants was very good.
Nanostructuring of titanium by SPD processing has made the
material with signiicantly superior mechanical performance when
compared to conventional cp Grade 4 titanium and Ti-6Al-4V alloy
(Figs. 13.5 and 13.6).
