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.

- 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
