RESUMO

The purpose of this study was to evaluate the flexion biomechanical resistance of two internal rigid fixation systems. The study which were mechanically tested in twenty sheep s hemimandibles, divided in two groups of ten in each. All mandibles were subjected to a ramus sagittal split osteotomy, followed by an advancement of 5 mm. The samples were measured to avoid discrepancies between them. Group A were fixed by three reabsorbable screws of 2.0 X 12 mm (Bionx Implants®, Tampere, Finland), inserted in positional way and disposed in inverted "L". The same happened in-group B, which were used metallic screws (Osteomed® CO. Addison, Texas - USA), with the same dimensions and design. The results showed no significant statistical difference between the groups. The reabsorbable system tested proved to be a viable alternative when compared to the metallic one
