Auxiliary attachment that used in orthodontics

1. Auxiliary attachment
Done by
DR.SAKHAA GARFAN
MSD

2. • Auxiliary are used as “aids” in orthodontic
treatment with fixed appliances, but which
alone cannot be used to carry out a complete
orthodontic treatment.

3. • Auxiliary include:
1.Elastics and elastic modules
2. Springs
3.Magnets
4.Buccal tube
5.Lingual attachment
6.Lock Pins
7-Bi-level Pins
8-Power Pins
9-Tip Edge Rings

4. Elastics
• They provide the cheapest and relatively reliable
force delivery.
Elastics can be of
• latex or
• non-latex material.
• Non-latex elastics deteriorate less as compared
to the latex elastics, in the oral environment.

5. • Elastics are available in various strengths,
which is dependent upon their diameter and
thickness.
• are chosen according to the purpose of their
use.
• They may be color coded
according to strength

6. Elastic modules or elastomeric links
• Elastic modules or elastomeric links They are made
of two elastic rings separated by a variable distance
• used to closed spaces or for derotation of teeth.
• 1- Closed or short elastic chain
• 2-long elastic chain
• 3- Continuous elastic chain

7. SPRINGS
• used as auxlliarios to generate tooth-moving
forces.
• mainly used for tooth uprighting and torquing
in the Begg appliance therapy and the tip
edge appliance.

8. Spring
• made from either stainless steel or nickel-
titanium alloys.
• The force generated by any spring is inversely
proportional to its length
• stainless steel springs will exert a greater force
than nickel-titanium springs

9. • Springs used along with the fixed orthodontic
appliances are:
1-Uprighting springs (to upright teeth)
. They move the tooth root in a mesial or distal
direction

10. 2- Rotating springs (to rotate teeth in a
particular direction)
• used in the vertical slots of the Begg and the
Tip-edge bracket.

11. 3-Torquing springs (to bring about root
movement)

12. 4-Open coil springs (to open or maintain or
regain space)

13. 5- Closed coil spring (to retract or close already
existing).

14. MAGNETS IN ORTHODONTICS
• used for the generation of tooth moving
forces in both repulsion (regaining lost space)
as well as attraction mode(space closure).

15. Applications of magnets in
orthodontics include:
• • Diastema closure (magnets used in
attraction mode)

16. • • Arch expansion (magnets used in repulsion
mode)

17. • • Distal driving of molars (magnets used in
repulsion mode)

18. • • Removable appliance for treating impacted
teeth (magnets used in attraction mode)

19. • • Active vertical corrector (magnets used in
attraction mode)

20. • • Magnetic bracket system.

21. Buccal Tubes
• are horizontal hollow tubes, round, rectangular or oval in
shape,
• used on molars and help provide better three dimensional
control of these anchor teeth.
Classification
based on mode of attachment
1-Weldable-can be welded on-to bands
2-Bondable-bonded directly to
the tooth surface

22. • Classified according to lumen shape as
• • Round (Fig. 39.34A)
• • Oval (Fig. 39.34B)
• • Rectangular (Fig. 39.34C)

23. • According to the number of tubes
• Single
• Double
• Triple

24. Classified according to the technique
• Begg tube (Figs 39.34A and B),
round or oval
• Edgewise tube (Fig. 39.35B
• Preadjusted edgewise (Fig. 39.35C)

25. Lingual Attachments
• Lingual buttons : attachment of
elastics.
• Lingual seating lugs : help in
seating of bands.
• Lingual eyelets :used to tie
elastic threads or ligature wires.

26. • Lingual cleats (Fig.
39.39) used for
attachment of elastics
• Lingual sheaths (Fig.
39.40) used for
attaching accessories
such as transpalatal
arches

27. • Lingual elastilugs (Fig.
39.41) These are used for
attaching elastics
• Lingual ball hooks (Fig.
39.42used to attach.

28. Lock Pins
• used to hold the wire in bracket slots in the
Begg technique or accessories in the tip edge
technique.

29. Bi-level Pins
• These can be used to capture auxiliaries
behind the tie wings of the tip edge brackets
(Fig. 43.13).

30. Power Pins
• Power pins (Fig.43.14A)are used for engaging
removable elastics or fixed elastomerics.

31. Tip Edge Rings
• These are designed to function exclusively
with tip edge brackets. They have lingually
facing lugs which wedge between the
archwire and the bracket and hold the teeth
upright during the finishing stages of the
treatment
