Torquing auxillaries /certified fixed orthodontic courses by Indian dental academy

  1. 1. TORQUING AUXILLARIES INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  2. 2. MOLLENHAUR”S ALIGNING AUXILLARY & ITS  The MAA attempts root control from the very beginning, without significantly affecting the anchorage and over bite correction.  The MAA is made from the 0.009” Supreme grade wire. www.indiandentalacademy.com
  3. 3.  Requirements for use of the MAA  1 . It must generalte very light moving forces.  The adjacent rectangles must not diverge by more than 45  The auxillary must be able to resist deformation- Supreme grade wire is used.  The base wire should be able to resist the reciprocal forces. www.indiandentalacademy.com
  4. 4.  5. MAA is engaged first and the main arch wire is piggy back.  Advantages of the MAA  1. Efficaci in intrusion and simulataneous retraction of the anterior teeth.  2.rapidly bodily alignment of the anterior teeth.  3. Stable results.  4. Reciprocability of torquing forces on the instandind laterals or palatally placed canines. www.indiandentalacademy.com
  5. 5.  5. Periodontal advantages.  Short stage III.  Various applications of the MAA  By bending more positive torque, it can be used after the stage I as a braking mechanism.  Applying labial root torque on the lower incisors in growing brachyfacial cases to prevent their roots from lingualizing. www.indiandentalacademy.com
  6. 6. mollenhauer can be used for controlling the mesio- distal root position.  This application is called MAA- tip.   Biomechanics of the MAA.  A. www.indiandentalacademy.com
  7. 7. Modified application of the MAA  The holding down the boxes for lingual root torque with the tail end of the lock pins was difficult.  In this modification, the torque is directly applied on the gingival surface of teeth.  It is made with the boxes inside the circle. www.indiandentalacademy.com
  8. 8.  When reciprocal root torque is required, the box meant for labial root torque rides over the main wire and presses against the incisal portion of the crown.  MAA is not used for unravellingcrowding. It is fitted only after enough space is created by distalizing the canines. www.indiandentalacademy.com
  9. 9. The torquing auxillary with spurs  The auxillary is made from 0.012” premium Plus wire.  Modifications:  1. Length of the spur- the length of the spur should be kept at least 5mm, leaving it about 1mm short of the gum to facilitate proper hygeine. www.indiandentalacademy.com
  10. 10.  2. Inclination of the spurs to the horizontal(occlusal) plane is kept 0.in other words the activation is 100%.  3. The angle of the spur from the inter spur span opens up and the legs of the spur tend to converge.  This is remedied by slightly over angulating the spur and by keeping it less divergent.  The distal leg of every spur is kept slightly shorter by about 0.5mm so that it does not project incisally to the main archwire. www.indiandentalacademy.com
  11. 11.  4. The inter spur span is curved as recommended by Kesling.a straight or angulated inter-spur span cannot assume a perfect curvature.  Correctly made auxillary having curved inter=spur span. www.indiandentalacademy.com
  12. 12.  Modifications of torquing auxillary  A. Reverse (lsbisl) torque on one or both the lateral incisors: Boxes at right angle to the plane of the spurs are made that lie at the incisal area of lat incisors  Crossover bends are made on either side of the lateral incisor bracket to permit the auxillary to pass over the base wire www.indiandentalacademy.com
  13. 13.  B. torquing boxes on the canines for lingual root torque: Boxes can be provided  The ends of the auxillary need not extend beyond the canine area www.indiandentalacademy.com
  14. 14. Some other torquing auxillary  1. Single root torquing auxillary :  it is useful design for any teeth except molars.  It is particularly indicated on upper premolar www.indiandentalacademy.com
  15. 15.  2.reciprocal torquing auxillary (SPEC) design.  It is employed when teeth require torque in opposite directions.  It is made in lighter 0.009” or 0.010” size wire if uded in stage I & II  If needed for the stage III it should be made in 0.012” www.indiandentalacademy.com
  16. 16.  3. Reverse torquing auxillary for cntrolling the roots of canine or premolars.  Designed by Franciskus Tan in 1987  It is used for labial root movement of palatally impacted canine.  For lingual root torque it is inverted.  It is made from 0.012”P wire in conjunction with 0.018” or 0.020” base wire www.indiandentalacademy.com
  17. 17.  In order to resist the palatal root torque on the molar that arises as a reaction from the auxillary the molars are stabilized with the help of TPA.  4. Buccal root torque on the molars.an additional auxillary made in 0.014” size wire isfitted in a round molar tubes.  It has boot design occlusal extensions on the molars. www.indiandentalacademy.com
  18. 18.  The auxillary need not be engaged in other brackets.  5. Labial root torque only on the lateral incisors: It is used for reducing the prominence of the canine roots  It is made from0.012” size arch wire www.indiandentalacademy.com
  19. 19. Uprighting springs in new australian wires The 0.014” size wire was used earlier but now 0.009” supreme grade wire is used.  Advantages Very light continious forces.  Less taxation on the anchorage  Ease in maintaining mouth hygeine and better esthetics. www.indiandentalacademy.com
  20. 20.  The new springs differ from the older springs in the following respects The coil of the spring is only twice the size of the wire; in contrast to the size of the former springs that was 4 times the wire diameter.  The stem of the spring runs tangential to the coil, unlike the previous springs in which the stem was radial to the coil. www.indiandentalacademy.com
  21. 21.  1oo% activation; the stem and active arm are in one line ie making an angle of 180 compared to the earlier 135 angulation www.indiandentalacademy.com
  22. 22.  Securing the springs  The ligature wire is passed through the bracket in front of the archwireand then passed behind the archwire outside the bracket and the two ends are twisted together.  The ligture tied in this fashion will leave just enough space for insertion of the spring stem, thus ensuring a snug fit. www.indiandentalacademy.com
  23. 23. Size of the coil- Mini Maxi or midi  Newer springs- mini springs  Conventionasl springs- maxi spring  The coil of the spring is very small.  The coils can be made bigger by winding it around the0.9mm spring winder tip.- midi spring.  These are generally made in 0.010” for incisors.  0.012” canines and premolars. www.indiandentalacademy.com
  24. 24. How to prepare a Spring winder? 2 pieces of wires are embeded in a cylindrical acrylic handle  One wire is kept at axial centre.  The other is kept at the side of the main arch wire.  Both are seperated by a distance of aout 1mm.  The diameter of the coil would be equal to the diameter of this projecting wire. www.indiandentalacademy.com
  25. 25. Project Goals  Ultimate goal of project  Relationship to other projects  High-level timing goals www.indiandentalacademy.com
