Abstract
Abstract After securement of brackets to teeth of a patent to be treated, an impression is taken of the mouth. The impression is removed, replicas of brackets are inserted in the impression and a simulation or model is made, as by positioning castings of the teeth made in the impression, in ideal locations in the model. Arch wires are then preformed to fit brackets on the ideal model and after preforming, the arch wire is transferred to the brackets previously mounted on teeth of the patient.
