Abstract

Coarse-grained titanium powder of high purity and not containing toxic ingredients is placed in to the one-sidedly closed casing (1), the casing (1) is placed into the forming matrix (4) and the powder is pressed with use of the extruder (5) to a density of at least 4050 kgm-3. The loose part of the casing (1) is removed, the casing (1) is closed and the powder is sintered, advantageously at the temperature from 1250 to 1450°C for 1.5 to 2.5 hours. The sintered material is repeatedly extruded, advantageously at least ten times, through the narrowed space in the matrix (4) using the CEC method of cyclic compression, advantageously at the temperature of 220 to 250°C. By this method a nano- titanium is obtained, which is then processed by drawing through the die (7), advantageously at the temperature from 160 to 200°C to form a body, advantageously a wire, which is the semis for manufacturing of a dental implant.
