  4. 2. Biomaterial Components Prepared by Titanium Powder Technology

    Author : Mikael Eriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dental; coping; biomaterial; titanium-hydroxyapatite composite; crown; cold isostatic pressing; deformation; titanium powder; high velocity compaction; powder metallurgy;

    Abstract : The main objectives of this work were twofold: First, to determine if a pressed-powder method could be used to fabricate titanium dental copings, and to line out what problems or benefits this new method would have. Second, to test if high velocity compaction of titanium powder could be used to form biomaterial components such as copings or dental implants. READ MORE
