Zirconium Dioxide
Zirconium oxide has shown clinical success in all the forms, namely, monoclinic, tetragonal, and cubic phases. It also attains a stable form when mixed with other metals. Stabilized zirconia with metal oxides is more favorable compared to pure zirconia due to tetragonal–monoclinic phase transformation at an elevated temperature of 1170°C.
Description
Zirconium oxide is a bio-inert nonresorbable metal oxide that is characterized by high hardness, superior mechanical properties, excellent chemical stability, and corrosion resistance and, therefore, can be used for hard tissue replacements (Piconi and Maccauro, 1999; Ferraris et al., 2000). Zirconia (ZrO2) ceramics were evaluated as biomaterials in the late 1960s and are currently used for dental implants (Akagawa et al., 1993) and orthopedic implants as ball heads in artificial hip joints (Piconi and Maccauro, 1999; Adolfsson and Hermanson, 1999).
Products Description
Zirconium oxide has a high affinity with bone tissue (Akagawa et al., 1993) and the structure of bone/implant interface was shown to be similar to that observed around Ti implants (Rosengren et al., 2002). Recent studies demonstrated that ZrO2 films fabricated by cathodic arc deposition exhibit favorable bioactivity and cytocompatibility (Liu et al., 2006). Bioinert ZrO2/SiO2 film was shown to be able to initiate HAp growth in simulated body fluid solution (Morks and Kobayashi, 2008). Note that the incorporation of bioinert compounds, such as ZrO2, into bioactive matrix can be useful for improving mechanical properties without substantial compromise in biocompatibility (Ji and Marquis, 1992).
