<h2>Abstract</h2> The classic in vitro studies of frictional resistance mostly utilize straight-line traction applied to the wire-bracket-ligation interface. Reports from these studies include relative quantification of either static or kinetic frictional resistance, but do not simulate the complexity of tooth movements observed with in vivo sliding mechanics. A prototype testing apparatus was designed, fabricated, assembled, and its performance evaluated. Results of the operating friction trials are reported as a function of integrated and quantified angular and linear bracket movements. The ability to integrate, in real time, linear and angular bracket displacement while maintaining precise positional control enables previously unattainable testing of the orthodontic archwire-bracket-ligation interface. In addition, flexibility to accommodate user-specificity is a highly desirable feature. It is concluded that the testing apparatus presented has the ability to allow for a high standard of basic hypothesis testing, product development, quality control, and product performance evaluation with relative ease.
