1. Fixed Appliences

2. Evaluation of Fixed Appliances in
Brief
Dr.Edward Angel - 1926.
- Father of Modern Orthodontics
- School of Orthodontics
- Edgewise Appliance
- 1st
bracket, Band
- Classification of mal-occlusion
- Proponent of non extraction treatment.

3. Edgewise
Slot
Bracket
Rectangular slot

4. Rectangular wire insertion for 3
dimensional control
Followers of Dr.Edward Angel
- Dr. Tweed
- Dr.Begg
Dr.Tweed popularized edgewise technique
and extraction therapy.
Dr.Begg popularized Beggs technique and
extraction therapy.

5. Begg Technique
Light wire technique, Round Wire technique.
Tooth movement is sequential and divided in
to three stages.
1st
stage- Alignment, decrowding correction
of deep bite bite and over jet.
2nd
Stage- Retraction of teeth and closure of
all the spaces.
3rd
Stage- Root uprighting and torquing.
4th
Stage- Finishing and detailing

6. Features of Begg technique
-1st
and 2nd
stages mainly include tipping of
teeth
- In the 3rd
stage tooth uprighting is done and
torque is done.
- Connection of root inclination in Labio
lingual direction is called as torquing of
roots.

7. Uncontrolled tipping Control Tipping

10. Edgewise system
Bodily Movement of teeth can be achieved
In 1971 Andrews introduced Preadjusted
Edgewise system
-Built in Tip and Torque in Brackets
-Reduction of number of stages
-Esthetically pleasing bracket system
-Excellent finishing and detailing.

11. Recent Advances in PEA
• Esthetic Brackets
• Composite Brackets, Plastic Brackets,
Ceramic Brackets
• Titanic Brackets (Nickel Free)
• Segmental Approach to reduce the
treatment time and more comfortable to
patient.

14. Begg Technique Advances
Tip Edge -
- Concept of both Beggs and Edgewise
technique
- Concept of light wire technique continued
- Rectangular wire finish
- Bracket design more pleasant and
comfortable than Beggs Brackets.

15. Orthodontic Treatment Planning

16. Class I Malocclusion
Skeletal Class I
-Proclination
-Bimaxillary protrusion
-Crowding
-Spacing
-High labial positioned canines.

17. Proclination:
-With space
- Without spacing

18. Pre treatment profile, Age:15yrs

29. Crowding
-Mild - 2-3mm
-Moderate - 3-6mm
-Severe - 6 and above

36. Class II cases:
Every growing period
1. Maxillary prognathism
Mandibular Normal
2. Maxillary Normal
Mandibular deficient
Vertical growing
Horizontal
growing

37. Treatment plan: to hold maxillary growth in
anterior and posterior plane and vertical
plane. Head gear can be given.
Following to orthopaedic treatment,
fixed treatment can be started in permanent
dentition.

38. Vertical maxillary excess long face,
incompetent lips, proclined incisors, infantile
swallowing pattern

39. Skeletal open bite with long face syndrome

40. Maxillary intrusion splint, with habit
breaker, with headgear.

41. Post orthopedic appliance

45. • Maxillary Normal
• Mandibular deficient

46. Treatment plan: Functional Appliance
Therapy to advance the mandible:
-Activator
-Twin block
-Bionator
This is followed by fixed appliance therapy.

57. • Prognathic Maxillary
• Retrognathic mandible
Treatment Plan:
Head and gear and Functional appliance
Class II Combination

58. Class II non growing:
1. Maxillary forward
2. Mandibular back.

59. Orthodontics
- Caumafluege
1. Upper extraction only 4 4
4 4
2. 4 4
4 4
3. 4 4
5 5
4. Non Extraction

60. Late growing years
• Fixed functional appliances
1. EVA Appliance
2. Jasper Jumper
3. S.U.S. Device
4. Fixed Twin Block
5. Herbst Appliance
6. Class II Corrector

61. Class II Div.
Feature :
a. Usually Mandible / Chin Prominent
b. ‘U’ Shape arches
c. Cetrals retroclined
d. Deep bite.

62. Treatment Plan:
1. Alignment of incisors
2. Intrusion of incisors and correction of
deep bite
3. Some times mandibular relocation takes
place in to class I
4. Growth Modulation through functional
appliance if no relocation.

63. Class III Growing
• Retraguathic Maxilla
• Normal Mandible
6-9 years:
Face mask, reverse pull head gear
9-13 years:
Facemask with rapid palatal expander

64. RPE to split the sutures and facilitates the
translation of maxilla forward.
After 16 years
Orthognathic Surgery

65. Growing mandible:
- Chin Cup
- Observe the mandible thought the growth
period.
- May require surgery at end of growth
period.
