At the 25th Anniversary Meeting of the Academy of Osseointegration, Dr. Jan Gottlow presented impressive results of an animal study that compared the implant stability of hydrophilic Straumann SLActive® implants and four competitor implant surfaces, all with non-hydrophilic surfaces. This study was performed in 40 rabbits and utilized removal torque measurement to assess implant stability. Measurements were taken at 3 and 6 weeks (120 implants per timepoint). The following five implant systems were included in the study:
- Straumann® SLActive®
- AstraTech™ OsseoSpeed™
- Zimmer® Tapered Screw Vent®
- Implant Direct® ScrewPlant®
- Osstem™ GS II Fixture
Results showed significant differences between the mean removal torque values of SLActive and the selected competitors’ implants at 3 and 6 weeks. The SLActive implants showed significantly higher implant stability compared to the implants with non-hydrophilic surfaces as assessed by removal torque evaluation.
