Abstract
Titanium is a good material for dental and orthopaedic implants, but m any authors reported that it releases ions into the surrounding tissue s and into the serum. Titanium nitride has good mechanical properties and chemical inertless and may be employed as an implant coating mater ial. In this experiment, pure titanium and SiO2 coated with TiN implan ts were inserted in the tibia of rats. After thirty days, the bones we re taken and examined by a proton microprobe. TiN-coated implants show ed a lower ion release into the bone compared with pure titanium. This suggests that TiN may be a good coating for endosseous implants.
