Özet
Objective: Zirconia dental implants are an alternativeto titanium. Various studies have been carried out in order to improvethe surface properties of zirconia implants like titanium implants. Theaim of this study is to evaluate the resistance and bioactivity of zirconia dental implant materials coated with different ratios of hydroxyapatite and wollastonite powders by plasma spray method. Materialand Methods: The bond strength between the zirconia and the coatings was measured according to the ASTM C-633 standard. The datawere obtained by using one-way analysis of variance. Differences between the groups were determined by Post Hoc Tukey HSD test. Examples prepared for bioactivity testing were kept in 37 oC simulatedbody fluid for 2, 7, 14- and 21-day periods. Changes in the samplesurfaces were analyzed by scanning electron microscopy using energy distribution x-ray spectrometry and x-ray diffraction device. Result: Bonding values of coatings containing different ratios of W werefound to be significantly higher than pure HA coatings (p<0.05). Conclusion: All sample groups used in the study showed bioactive properties in simulated body fluid.
