E-mail: manudrago@hotmail.com The use of materials produced from bovine bone has been proposed in the manufacture of implants such as pins, plates and screws, due to their osteoinductive and osteoconductive properties or functions of bone graft. However, structural and mechanical aspects must be evaluated prior to the use, in vivo of bone implants. The aim of this study was to evaluate mechanical strength, through a mechanical bending test, of plates produced from bovine cortical bone, used to repair fractures of the tíbia of rabbits ex vivo. Twenty six plates were manufactured from bovine cortical bone and stored in saturated salt solution. Three study groups were used: group GP (n = 10), made up of the bone plates; GTP group (n = 16), rabbit tibia osteotomized and stabilized with bone plates and four screws and Group GT (n = 10), intact tibia. A three-point bending biomechanical test was used to determine the maximum tension, maximum deflection, and stiffness. The results were submitted to Kruskal-Wallis test (p
