Variations of the Begg technique: A preliminary report

Abstract

I have briefly reviewed Begg's light wire technique and described certain variations evolved in my use of the technique. Application of the variations to the management of specific orthodontic problems has been discussed. This is a preliminary report. I have not treated a large enough number of cases over a period of years to be able to state my results categorically as clinical facts. Thus far (1959) I have treated 105 cases of various types of malocclusion by this method. The gratifying results that I have obtained have led me to concur with Begg's claims concerning the advantages of the technique: 1. 1. The resilient light wires deliver optimum force for simultaneous tooth movement. 2. 2. The vertical spurs and loops give adequate tooth control. 3. 3. One thin round wire with a minimum of adjustment produces most of the required tooth movement. 4. 4. Treatment time is reduced. Fewer appointments and less chair time are necessary for each patient. 5. 5. The method causes little discomfort to the patient. 6. 6. Because of the rapidity of action, there is reduced appliance breakage. It would also appear that the previously outlined adaptations of the Begg mechanism have certain additional practical values to recommend their use: 1. 1. Substituting the 0.10 inch double-width edgewise bracket for the ribbon arch bracket makes the technique compatible with edgewise procedures. 2. 2. Continuing the vertical loops in the posterior section of the arch wire promotes better root control of the premolar teeth. There is less adverse bending of the light wire because of mastication or occlusal interference. 3. 3. Forming the arch wire on a diagnostic setup with all of the brackets in place produces a sureness of design that is not otherwise easily attainable. The use of diagnostic setups before treatment has been advocated, but, to my knowledge, this particular setup has not been previously described. It appears to have a significant potentiality as a treatment adjunct, since it provides a predetermined objective upon which all necessary arch wires may be formed. Since this is a preliminary report, numerous documented cases long out of retention have not been presented. In time, a more critical appraisal of the stability of results will be possible.
