English abstract
Background: Cell interactions, adherence, and osseointegration at the bone-implant interface can be directly influenced by the surface properties of the titanium implant. Purpose: To characterize osseointegration of Neoss (R) implants with conventional (control group) and hydrophilic (test group) surface treatments. Materials and Methods: Six Labrador dogs received Neoss implants with conventional and hydrophilic surfaces. The bone-implant interfaces were evaluated 1 and 4 weeks after implantation, and osseointegration was evaluated using histological, histomorphometric, fluorescence, and resonance frequency analyses. The surfaces were also subjected to topographic and hydrophilicity analyses. Results: The topographic analyses revealed increased surface roughness in the test group compared with the control group (surface area roughness 0.42 and 0.78 mu m, respectively, for control and test group surfaces; p <= .05). The wettability values were higher in the test group (contact angles 67.2 degrees and 27.2 degrees for the control and test group surfaces, respectively; p <= .05). Implants in the test group also exhibited better stability, more bone-implant contact, and increased bone area compared with implants in the control group. Conclusion: Neoss implants in the test group improved bone formation in the early stages of osseointegration compared with implants in the control group.
