1. A general consideration of
Stage I in Begg Technique.

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

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.

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. • 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. • 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. • Orthodontic apparatus in Stage I.
• Attachments – Bands, brackets, tubes &
•
•
•
•
lingual cleats.
Archwires
Ligatures.
Elastics.
Auxiliaries.- Rotation springs.
www.indiandentalacademy.com

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. • 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.

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. • 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. • 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. • 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. • 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. • 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. • 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. • Rate of progress.
• Amount of space remaining.
• Location in looped archwire.
• Non – extn. cases
• 1st molar extn. cases.
• 2nd Premolar extn. cases.

Nearer
the
tube

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.
