Bends in Beggs Technique /certified fixed orthodontic courses by Indian dental academy

  1. 1. BENDS IN BEGGS TECHNIQUE INDIAN DENTAL ACADEMY Leader in continuing dental education
  2. 2. Bite Opening Bends Begg Technique is universally acknowledged for its efficient bite opening mechanics, which is indeed one of the strength of the technique. This is the procedure where there is incorporation of bends in the arch wire so that it helps in the intrusion of the anterior teeth and extrusion of the molars. Many authors have proposed different sites for the bite opening bends in the arch wire.
  3. 3. Anchor Bends First in the Conventional Begg’s , anchor bend is placed 3 mm mesial to the molar tube in such a way that there is gingival displacement of the anterior part of the arch wire therefore when the arch wire is placed in the bracket, there is a intrusive force acting on the anterior segment.
  4. 4. Gable bend This is a modified bite opening bend given in the arch wire distal to the canine. This tends to cause relative extrusion of the canines and the intrusion of the central and laterals.
  5. 5. Hocevar’s modification In a modification given by Hocevar, bite opening bends are placed on either side of canine, which results in more intrusion of central incisors and relative extrusion of lateral incisors and canine.
  6. 6. Mollenhauer’s modification In a modification given by Mollenhauer, where a bite opening curve is given, it will result in extrusion of the canine and intrusion of central and lateral incisors
  7. 7. Kameda’s modification In this modification both the anchor bends and gable bends are given, there is extrusion of the canine and intrusion of the incisors
  8. 8. Swain’s modification Swain advocates giving a mild gingival curve in the anterior region which starts from mesial side of one canine to the mesial side of the other canine for the better intrusion of the anteriors.
  9. 9. Vertical step up bend This intrusive action can be further augmented by incorporating a vertical step up bend 3mm in height mesial to the molar tube. After giving this bend, anchor bend of required degree can be given in the upper end of the step up bend.
  10. 10. Power arms The power arms are made from .017×.025 or larger size wire. The optimal length of the power arms is about 5−7mm and follows the contour of the alveolus. The power arms are soldered to the bands, just above the molar tubes.
  11. 11. Palatal elastics from TPA This modification given by Prof. Dr. Jayade TPA is fitted only after the molar relationship is corrected, incisor proclination reduced and spacing closed. The TPA carries a hook that is bent into the TPA itself or soldered to it.the hook should lie in line with that of the lateral incisors.
