Abstract:
This study was performed to evaluate the effect that screw number and length have on the ability of two types of plate to resist vertical masticatory force. Five trials were done with two, four, or six screws, using screws 4 mm, or 12 mm in lenght and mini bone plates or mini compression plates. The fractured ribs were subjected to increasing weights until failure. With the mini bone plate, increasing the number of screws increased the weight resisted than screw length. For the mini compression plate, increasing screw length and the number of screws increased weight resisted.
