Rectangular Wires as substitutes for the MAA and a Torquing Auxiliary in the Begg treatment - An Experimental study

An experimental set up consisting of an upper typodont with ivorine teeth was employed. It was fitted with the Begg brackets. Rectangular wire sectionals in 0.016"x 0.022", 0.017" x 0.025", 0.018" x 0.025" and 019" x 0.025" sizes and made of Stainless Steel, Braided Stainless Steel, Superelastic NiTi, Braided NiTi, Copper NiTi, a -Titanium and BTitanium were tested. The MAA and the four spur torquing auxiliary were made in 0.009" supreme grade and 0.012" premium plus grade wires respectively. Torquing forces generated by the above wi res inserted in the ribbon mode and the auxiliaries were accurately measured using a dial gauge and components of an electric circuit. Force comparisons were drawn to find out if forces generated by any\of the rectangular sectionals were comparable with those generated by the MAA and the four spur torquing auxiliar.
