Karin E. Sisti, DDS, Fellow PhD1,2,3* Rafael de Rossi, PhD4 Andreia M. Brochado Antoniolli, PhD3 Ricardo D. Aydos, PhD3 Antonio C. Guastaldi, PhD2 Thallita P. Queiroz, DDS, Fellow PhD2,5 Idelmo R. Garcia Jr, PhD6 Adriano Piattelli, PhD7 Hewerson S. Tavares, DDS, Fellow PhD8 Surface and biomechanical analysis of titanium implant surfaces modified by laser beam with and without hydroxyapatite. Titanium implants with 3 different surfaces were inserted into the tibias of 30 rabbits: group I (GI) machined surface (control group), group II irradiated with laser (GII), and group III irradiated with laser and hydroxyapatite coating applied— biomimetic method (GIII). Topographical analysis with scanning electron microscopy was made before surgery in the tibia. These rabbits were distributed into 2 periods of observation: 4 and 8 weeks postsurgery, after which biomechanical analysis (removal torque) was conducted. Statistical analysis used the Student-Newman-Keuls method. Surface showed roughness in GII and GIII. Biomechanical analysis demonstrated values with significant differences in GII and GIII. Titanium implants modified by laser irradiation can increase osseointegration during the initial phase. Key Words: rabbits, lasers, titanium, dental implants, durapatite
