| Sumario: | Objective: To compare, through biomechanical torque tests and resonance frequency analysis, Oxalife surface titanium implants, without and with vitamin C, placed in rabbit femurs. Methods: 17 Tree-Oss Rapid surface Oxalife implants of 7 mm in length and 3.3 mm in diameter with external hexagon connection were used, placed in the femur of 8 hybrid breed rabbits. Following the drilling sequence indicated by the manufacturer. Insertion torque and resonance frequency analysis were recorded to measure the initial stability coefficient. Euthanasia was performed at 60 days; then the implants were exposed to measure the final or biological stability coefficient through resonance frequency analysis (Osstell) and removal torque (Mark-10 Gauge). The data were subjected to parametric contrast Student test. Results in Ncm: Mean insertion torque value for the experimental group 16.5 ± 3.7 and for the control group 23.3 ± 4.2, with a significant difference (p<0.01). Mean removal torque for the experimental group 69.3 ± 17.4, and control group 87.2 ± 24.9 without significant differences (p=0.14). Average initial ISQ for the experimental group 40.2 ± 7.8 and for the control group 44.7 ± 6.9 (p=0.24). Final ISQ average for the experimental group 50.8 ± 1.1 and for the control 50.5 ± 2.0 (p=0.77) without differences in both measurements. Conclusion: The addition of vitamin C on the surface of the implant would not have a significant effect regarding the stability values during osseointegration |
