ABSTRACT
Objective:
To design and assemble an orthodontic friction prototype testing apparatus and evaluate its performance.Methods:
Simulating progressive tooth tipping movement,results of the opera-ting friction trials are reported at different archwire-bracket angulation.Results:
An orthodontic friction testing apparatus was designed and developed,by which the complexity of tooth movements observed with in vivo sliding mechanics was simulated and a series of in vitro friction experiments were conducted.This friction testing apparatus enables previously unattainable testing of the orthodontic archwire-bracket-ligation interface.In the passive configuration or the active configuration with second-order angulation,the friction in sliding mechanics was measured.Conclusion:
The apparatus presented has the ability to allow for a high standard of basic hypothesis testing,product development and performance evaluation with relative ease.Furthermore,it will be the prototype of a computer-controlled multifunctional friction testing device in the near future.
