A biomechanical comparison between original and used titanium miniplates.
Four dogs were chosen for this study. An experimental fracture was made in the mandibular symphysis region of each dog. Two miniplates and eight screws were applied, and removed three and six months postoperatively. In this study, the surface and mechanical characteristics of titanium miniplates were evaluated. Study materials consisted of four groups. In each of the groups, there were six miniplates. The groups are as follows: Group A: Original plates (not used) as a control (i.e. used as a reference in comparisons) Group B: Original plates bent as in operation but not left in tissue Group C: Plates removed at third month postoperatively Group D: Plates removed at sixth month postoperatively. After evaluation of all groups, there was no difference in the microstructure of the surfaces but some differences in mechanical characteristics were apparent.
