1. Fixed orthodontic appliances deliver precise forces to teeth to correct malocclusions and include brackets, wires, and elastics.
2. The Begg and Edgewise techniques popularized the use of fixed appliances; Begg emphasized light forces while Edgewise allowed three-dimensional control.
3. Modern preadjusted appliances provide built-in tip and torque for improved control of tooth movement and alignment.

4. Evaluation of Fixed Appliances in
Brief
Dr.Edward Angle - 1926.
- Father of Modern Orthodontics
- School of Orthodontics
- Edgewise Appliance
- 1st
bracket, Band
- Classification of mal-occlusion
- Proponent of non extraction treatment.www.indiandentalacademy.
com
6. Rectangular wire insertion for 3
dimensional control
Followers of Dr.Edward Angle
- Dr. Tweed
- Dr.Begg
Dr.Tweed popularized edgewise technique
and extraction therapy.
Dr.Begg popularized Beggs technique and
extraction therapy.www.indiandentalacademy.

7. 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 detailingwww.indiandentalacademy.
com
8. 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. www.indiandentalacademy.
com
12. 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.

13. 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. www.indiandentalacademy.

56. 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.www.indiandentalacademy.
