| ABSTRACT Introduction: Implant-supported orthodontic treatment has gained an expanded interest by researchers and orthodontists in the recent years. Therefore, different methods were tried to achieve the best results in this kind of treatment. Aim of the study: The current research was conducted to compare the effect of 2 different treatment methods on the surface of orthodontic titanium mini-screws and on bone response to the treated implants. Materials and methods: Forty-eight titanium mini-screw implants were distributed under 3 equal groups; as received, sandblasted, and laser-treated, respectively. After application of the surface-treatment methods, half of the selected screws were tested for surface morphology, using a scanning electron microscope (SEM) and a digital profilometer. To evaluate the biological effects of surface treatment methods, the other screws were implanted in rabbits’ tibias which were subjected to histological examination at the end of the experimental periods of 4 and 8 weeks. The surgical procedures and euthanasia were conducted according to the limitations of Research Committee of Mansoura University. Results: Sandblasted implants showed the highest surface roughness and the most pronounced bone response. Conclusion: Sandblasting surface treatment provide more favorable conditions for implant osseointegration, in comparison to laser-treatment. | ||||
