Molar distalization in begg technique /certified fixed orthodontic courses by Indian dental academy

  1. 1. MOLAR DISTALIZATION IN BEGG TECHNIQUE. INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  2. 2. Recent advances in mechanotherapy and change in the concept of treatment has increased the clinician’s interest in avoiding extractions in moderate discrepancies. A popular method for creating additional space within the dental arch is by distalization of molars. www.indiandentalacademy.com
  3. 3. What one should look for, to consider a case for molar distalization? 1. Normal or near normal mandibular arch. 2. Profile consideration: Well developed nose and chin, have better chances of tolerating slight proclination. 3. Age of the Patient:- the success of molar distalization is greater in growing children, usually in late mixed dentition and early permanent dentition. www.indiandentalacademy.com
  4. 4. Mst.Sachin . Age: 9.8yrs. Mild :Class II Div. I HORIZONTAL GROWTH PATTERN www.indiandentalacademy.com
  5. 5. www.indiandentalacademy.com
  6. 6. www.indiandentalacademy.com
  7. 7. 4. Inclination of Molars:- OPG forms an ideal diagnostic tool. If the first and second molars are distally angulated, the case is contraindication for molar distalization. 5. Amount of available posterior space and 3 rd molars: Usually absence of 3rd molar is advantageous for molar distalization. Distal angulation of 3rd molars is, again a contraindication and it is indicative of posterior crowding. 6. Growth Pattern – vertical growth pattern is a contra – indication for distalization. www.indiandentalacademy.com
  8. 8. www.indiandentalacademy.com
  9. 9. www.indiandentalacademy.com
  10. 10. How to identify molar distalization case: 1. End on molar relationship with mild to moderate space requirement in the maxillary arch. 2. a) High labially placed canine / unerupted canine, with end-on or full cusp class II molar relation. b) Ectopic eruption of 1st or 2nd premolars. www.indiandentalacademy.com
  11. 11. These above two conditions may be caused by premature loss of deciduous tooth and forward migration of the upper permanent molar. www.indiandentalacademy.com
  12. 12. 3. During late mixed dentition, when lower E space is to be utilized for relief of lower anterior crowding. Here the lower molars are held back, and utilizing the E space anterior crowding can be corrected. In such cases molar distalization in the upper arch helps in changing a class II molar relation to Class I relation. www.indiandentalacademy.com
  13. 13. METHODS OF MOLAR DISTALIZATION IN COMMON USE ARE:   1.     Use of extra-oral force    2. Wilson Bimetric arch design      3. Modified Nance lingual appliance for unilateral                molar distalization.    4.     Pendulum appliance    5.     Lip bumper    6.     Use of Japanese NiTi coil springs  www.indiandentalacademy.com
  14. 14.    7. Distal Jet Appliance    8.  Jones Jig    9. K-loop appliance   10. Molar distalization with magnets   11.  Removable distalization appliance   12.  Sagittal appliance. Undoubtedly, most of the above mentioned molar distalization techniques can be effectively used with the Begg technique. www.indiandentalacademy.com

  20. 20. MODIFIED BIMETRIC ARCH DESIGN: In  our  department  we  use  a  slight  modification  of  original  WILSON’S BIMETRIC ARCH. The upper arch wire is  made from 0.16” premium SS wire.  The arch  wire  is  shaped  in  an  ideal  form.  Cuspid  circles  are  kept  abutting  the  cuspid  bracket.    Two pear shaped loops, one on each side, are  made, 6-7mm in height and 4mm in width at  the  top  and  almost  touching  each  other  at  bottom.   www.indiandentalacademy.com
  21. 21. About  45°  bends  is  placed  equally  distributed  on  either side of the loop for simultaneous intrusion of  anteriors. Mild toe in is given for molar segment.   www.indiandentalacademy.com
  22. 22. www.indiandentalacademy.com
  23. 23. Opening loops by 2mm on each side activates  arch  wire  in  the  anterior  segment,  which  is  then  ligated  into  brackets.  This  causes  expansion  forces  in  the  labial  or  buccal  direction  in  the  incisor  canine  and  premolar  area.  This expansion force is resisted by using  class  II  elastics  on  elastic  load  reduction  principle.  Hence  the  force  is  transferred  onto  the molars, in a distal direction.  www.indiandentalacademy.com
  24. 24. www.indiandentalacademy.com
  25. 25. ELASTIC LOAD REDUCTION PRINCIPLE The patient is asked to use class II elastic in a definite sequence, namely – TP green elastics for 1st week, pink elastic for 2nd week and yellow for the following 2-3 weeks, all in class II fashion. The initial heavy elastic force of green elastic is required to resist the forward pushing force of the arch wire, thus transferring it in a distal direction to the molars. www.indiandentalacademy.com
  26. 26. As the molar becomes upright, the distally directed archwire force acting on it diminishes. Thus a slightly lesser force with pink elastics and finally with light yellow elastic is applied. About 1mm of distal movement of upper molars can be achieved per month. The archwire is activated for 3 visits for the required amount of correction. Employing this procedure, a suitable borderline case can be converted into a non-extraction case. www.indiandentalacademy.com
