Notes:
The production of titanium parts from powder metallurgy is one of the tendencies ofmodern metallurgy, since it allows obtaining structures with complex geometries and controlledporosity. The purpose of this study was to produce two types of dental implant prototype, andcompare them biologically. Smooth surface prototypes were obtained, by the conventional turningprocess and porous surface prototypes using Metal Injection Molding (MIM). The prototypes wereimplanted in rats that were euthanized after 3 weeks, and the bone/implant interface was analyzed.The results showed that all prototypes were clinically stable at the end of the healing period, butthose produced by the MIM process presented a significantly higher percentage of osseointegration(bone/implant contact) than the milled prototypes in the same healing period. It is concluded thatthe bone tissue grew independent of type of implant, enabling quick, rigid fixation already in thethird week of the healing process
