A general consideration of stage i in begg /certified fixed orthodontic courses /certified fixed orthodontic courses by Indian dental academy

  1. 1. A general consideration of Stage I in Begg Technique. INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  2. 2. Introduction • General objective of any ortho trt. – to • • • • aobtain a result that simulates normal occlusion. With Begg tecchnique objective achieved by dividing trt. into 3 stages. Stages I and II – Crown tipping phase. Stage III – Root tipping phase. Stage IV – Finishing phase www.indiandentalacademy.com
  3. 3. • Overlapping of the stages must be avoided. • Ie. Objectives of each stage met before • • proceeding Therefore better results and fewer problems are encountered. Division into stages – to prevent anchorage failure – Teaching and learning made easier. www.indiandentalacademy.com
  4. 4. Objectives of Stage I • • • • Correction of crowding and irregularity Closure of anterior spaces. Correction of rotations. Elimination of deep bites -edge to edge bite / openbite except in class III www.indiandentalacademy.com
  5. 5. • Openbites  Overbite relations • Correction of Mesiodistal relations of buccal segments – Class I and Class II  Mild class III – Class III  Class I or Class II • Co-ordination of upper and lower arches. www.indiandentalacademy.com
  6. 6. • Correction of anterior and posterior cross bites. • Axial relation of anchor molars corrected – upright position. – Extraction spaces become smaller – All tooth movements carried out simultaneously & in both arches. www.indiandentalacademy.com
  7. 7. • Orthodontic apparatus in Stage I. • Attachments – Bands, brackets, tubes & • • • • lingual cleats. Archwires Ligatures. Elastics. Auxiliaries.- Rotation springs. www.indiandentalacademy.com
  8. 8. • Apparatus applied simultaneously – – to avoid breakage Act simultaneously to reciprocal adv. with each other – Creeping into trt. Also avoided  Severe loss of anchorage. www.indiandentalacademy.com
  9. 9. • Material – Archwires – – – – 0.016 special AJW – principal wire of Stage I. Combination of resilienbcy and flexibility. Adequate stiffness for bite opening Developed by rigid control in wire drawng and heat trt. – 0.018 special – Molar extraction cases – 0.014 special – rotating springs. www.indiandentalacademy.com
  10. 10. • • • Parts. Intermaxillary Hooks – ( IMH ) Small loops for engaging elastics and cuspid ties – 2 types – • Boot • Circle/ Helical – Adv of Circle hook. • 2 – 2.5 outside dia. • Mesial & Distal rolling possible • Less space requirement. • Less distortion • Greater stiffness in horizontal and vertical plane. www.indiandentalacademy.com
  11. 11. • Location – Well aligned ant. – 1-2 mm mesial to the cuspid bracket. – Spaced ant. – Farther mesially. – Mildly crowded ant. – impinging on the bracket. – Severley crowded – multi loop wires. www.indiandentalacademy.com
  12. 12. • Anterior Segement. – Portion of the wire b/w intermaxillary IMH lies gngival to buccal segment for effective intrusion – Reverse curve at midline – 2-3 mm elevated form occusal plane for even intrusion. www.indiandentalacademy.com
  13. 13. • Cuspid Offset bend. – Horizontal offset bend mesial to the IMH. – Proper positioning of the cuspid and the lateral incisor. • Cuspid Curve: – Labial curvature in cuspid area – incorporated to avoid lingual tipping of canines. – In narrow arches requiring expansion, cuspid offset given. www.indiandentalacademy.com
  14. 14. • Anchorage bends / Tip back bends. – In buccal segment of the archwire mesial to the tube with vertewx facing occlusally. • Angulation depends on – – Stage of trt. - as stage progresses. – Depth of overbite - with bite opening. – Rate of progress of case. www.indiandentalacademy.com
  15. 15. • Inclination of anchor molars. – Mild to moserate inclination – slight anchor bend. – Severe inclination – Initially no anchor bend. – Later gradually increases anchor bend to upright the molar. – No intrusion of anteriors beyond edge to edge or mild openbite. www.indiandentalacademy.com
  16. 16. • Location depends on – Time elapsed since commencement of trt. – as far mesially. – Distal to ccuspid bracket. – In mild open bite and overbite – anchor curve. • Depth of overbite. – Greater reduction in overbite if closer to the molar tube. www.indiandentalacademy.com
  17. 17. • Rate of progress. • Amount of space remaining. • Location in looped archwire. • Non – extn. cases • 1st molar extn. cases. • 2nd Premolar extn. cases. www.indiandentalacademy.com Nearer the tube
  18. 18. • Toe in and toe out bends. – Horizontal offset bends combined with anchor bends. – Anchorage bend bent lingually – toe in. – Anchorage bend bent buccally – toe out. www.indiandentalacademy.com
