RESUMEN
Introduction: The invention of dental implants has replaced the fixed partial dentures for the replacement of the teeth. Hence, in the present study, we compared the surface characteristics of various zirconia dental implant systems. Materials and Methods: We conducted an in vitro comparative study of 50 implants of the dental implant systems "Straumann pure ceramic implants (SC) and Bredent dent whiteSKY™ (BW)." Scanning electron microscopy (SEM) was used to compare the groups for the surface characters at the different regions of the implant surface. Results: SC showed deep markings on the surface and droplets, and BW showed smoother surface and bigger droplets under the SEM. Conclusion: SC may perform better in the clinical conditions as the surface characters are better than the BW.
