Abstract

The Regional Innovation and Technology Transfer Center specialized in Materials, Coating and Surface Treatment located in Charleville-Mézières(France) together with the Biomechanics-Bioengineering unit(CNRS UMR 7338)of the University of Technology of Compiègne(France) have carried out together experiments aimed at the biological characterization of materials produced by Powder Injection Moulding (PIM). The goal of this study was to promote the use of PIM materials for dental applications in order to widen the potential applications of this technique. We have focused our biocompatibility trials on two alloys: - The titanium alloy,TiAl6V4, a well-known biocompatible metal used for dental implants in contact with bone tissue - The homogeneous composite 90% Titanium-10% Zirconia for abutments in contact with epithelial tissue In conclusion, PIM process allows the production of materials with good biocompatibility regarding the osseointegration as well as soft tissue adhesion compared to traditional materials for the dental practice.
