This work evaluated the laser (AsGaAl) laser effect by torque removal method, in different healing periods, of smooth and texturized standard model implants, installed in male New Zealand rabbit tibiae, submitted or not to low intensity laser irradiation. For the study, 16 animals, weighing between 3. 5 to 4. 0 kg, with two implants in each tibia, divided in four groups (control and laser for 16 and 30 days of healing) have been used. The laser (AsGaAl) was irradiated with a wave length of 830 nm, continuous mode and power of 100 mW, and the punctual application was 1 J/cm2 in three points and eight applications, with 48 hours intervals, started immediately after the implant installation surgery, in a total of 24 J/cm2. After the healing period, the animals were sacrificed and the tibiae were removed for the implant torque removal measurements with a manual digital torquemeter. The torque removal results for the control groups were: smooth implants, 16 days, 20. 42±3. 06Ncm, and 30 days 27. 42±19. 65Ncm; texturized implants, 16 days, 22. 67±11. 07Ncm, and 30 days 30. 46±16. 06Ncm. for the laser groups, the results were, smooth implants, 16 days, 19. 15±4. 65Ncm, and 30 days, 30. 08±4. 14Ncm; texturized implants, 16 days, 20. 48±6. 72Ncm, and 30 days, 23. 45±10. 40Ncm. The Factorial Analysis of Variance showed that there is a significant difference for this research results if only the time factor is analyzed and it has been observed that, on the 30 days period, the torque removal values are higher than those for the 16 days period.
