of mesially angulated canines

1.25 mm diameter SS
Function: transverse expansion,
buccal crossbite correction

15. Active component of Removable Appliances
Screw
Function:
Expansion and distalization
Activation: 1 turn / week = 0.25mm
(1/4 turn)

16. ELASTICS Rubber or Latex rings Used in: Extra oral traction
Inter-intramaxillary traction
Patient cooperation

17. Retentive components

18. Types of Clasps 1. Adams Clasps 2. Southend Clasps 3. Labial bow
4. Ball-ended Clasps
5. Delta Clasps

19. Retentive component of Removable Appliances
Adams clasps
0.7 mm diameter SS on molars
0.6 mm SS on premolars, canine and deciduous molar

20. Retentive component of Removable Appliances
Southend clasps
0.7 mm diameter SS
Function:
Useful when distal movement of canines required

21. Retentive component of Removable Appliances
Labial bow
0.7 mm diameter SS
Function:
Retention
important when mesial / distal
movement is planned

22. Retentive component of Removable Appliances
Labial bow
Short labial bow
Long labial bow

23. Ball- ended Clasps 0.7 mm diameter SS Undercut interproximally
minimal retention

24. Delta Clasps
0.7 mm diameter SS
Difficult to adjust

25. Anchorage Definition: the resistance to unwanted tooth movement
equal in magnitude and opposite in direction

26. Types of intra oral Anchorage
Simple
Reciprocal
Stationary
Intermaxillary

27. Types of INTRA ORAL Anchorage
Simple Anchorage
Active movement of few teeth versus several anchor teeth

28. Types of intra oral Anchorage
Resiprocal Anchorage
When two teeth or two sets of teeth move to an equal extent in an opposite direction

29. Types of intra oral Anchorage
Stationary Anchorage
Bodily movement of one group of teeth against tipping of another

30. Types of intra oral Anchorage
Intermaxillary Anchorage
When the anchorage units situated in one jaw used to provide the force required to move teeth in the opposing jaw

31. Baseplate
1. Hold components 2. Clear acrylic : - heat cure - cold cure - autoresin 3. Comfortable 4. Good fit 5. Can be active - biteplanes

32. Baseplate
Posterior biteplanes
Anterior biteplanes

33. FUNCTIONAL APPLIANCES
Removable or fixed orthodontic appliances which use forces generated by the stretching of muscles, fascia, and /or periodontium to alter skeletal and dental relationships

34. TYPE OF CASE
For correction of moderate to severe Class II div I and Class II div 2
Less for correction of Class III due to much lower success

35. INDICATIONS PATIENT Growing patient Motivated patient DENTAL
Classic case: uncrowded, well aligned
Functional appliance have non-mechanism for treating irregularities of alignment of teeth
SKELETAL
Moderate to severe Class II skeletal base
Normal to low MMPA

36. CONTRA INDICATIONS Non-growing Non compliance
Labial tipping of lower incisors
Care needed with:
High angle cases with backward mandibular growth rotation
Cases with proclined lower incisors

37. TYPES OF FUNCTIONAL APPLIANCE
TWIN BLOCK
THE ANDRESEN ACTIVATOR
THE HARVOLD ACTIVATOR
HERBST APPLIANCE
MEDIUM OPENING ACTIVATOR
BIONATOR
FRANKEL APPLIANCE
Others

38. Twin block appliance
The upper and lower parts fit together using posterior bite blocks with interlocking biteplanes which posture the mandible forward

39. The Andresen Activator

40. Herbst Appliance
A fix-functional appliance.

41. Bionator
Minimal bulk

42. The Frankle Appliance Is a functional regulator and uses shield.
Complex, uncomfortable, rapid changes if worn properly.
Three main variants:
FR1: Class II div 1
FR2: Class II div2
FR3: Class III

43. WEAR 12-14 hrs-Andresen, Harvold, Bionator
Full-time- twin block, Herbst, Frankel (except for eating and sports)

44. appliance which is fixed to teeth and cannot be removed by the patient
FIXED APPLIANCES
appliance which is fixed to teeth and cannot be removed by the patient

45. COMPONANTS OF FIXED APPLIANCE
1. Attachments include bands (especially on 1st and 2nd molars) & brackets bonded directly to the teeth (especially on anterior & premolar teeth) .
2. Axillaries (attach arch wire to brackets and bands
to move teeth such as tubes, hooks and elastics
3. Arch wires are attached to the brackets by bending the wire, it
will give force and pressure that cause teeth to move in the
desired direction .
