Fracture of polycarbonate brackets--a related photoelastic stress analysis.

  • NHS Dumfries and Galloway

Research output: Contribution to journalArticlepeer-review

Abstract

In clinical use polycarbonate edgewise bracket designs, patterned on metallic predecessors, have demonstrated slot-wing fracture. A preliminary two-dimensional photoelastic stress investigation is described in which two bracket designs, without angles in the edgewise slot component, are subjected to simulated palatal root torque mechanics.
