Bracketing for dental assistants

  1. 1. Bracketing: A Basic Teaching Module for Dental Assistants Dr Jean Marc Retrouvey McGill University, Faculty of Dentistry
  2. 2. General steps in bracket bonding
  3. 3. Prophylaxis • Pre-bonding prophylaxis procedure – Using oil-free pumice mixed with water: tooth surfaces where the brackets are to be bonded must be cleaned.
  4. 4. Isolation of teeth (Cheek retractors)
  5. 5. Acid Etching
  6. 6. Proceed by quadrants
  7. 7. Apply a light coat of resin
  8. 8. Select the proper bracket
  9. 9. Position the bracket as precisely as possible
  10. 10. Use a mirror to verify if the bracket is centered on the crown
  11. 11. Excess composite Remove excess composite around the bracket with a scaler or an explorer before light curing. If not, it will encourage plaque accumulation.
  12. 12. Use height gage properly
  13. 13. In the canine, premolar and molar regions, the gauge is placed parallel with the occlusal plane
  14. 14. Verify bracket positioning
  15. 15. Tip and Torque in the position of incisors
  16. 16. GENERAL ORTHODONTIC INSTRUMENTATION FOR FIXED APPLIANCES
  17. 17. Examination kit • Cotton pliers. This instrument is used to hold brackets securely when placing them onto the tooth surface. • Explorer. In orthodontics, this is commonly used to remove elastics, in place of a scaler. In addition, it can be used to remove excess resin after bracket placement. • Mouth mirror. This is used to verify the MD position of the bracket
  18. 18. Bidirectional ligature director. This instrument is used to tuck metal ligatures under the archwire, to keep the ends free from irritating the soft tissue. Bracket height gauge. This is used to measure the distance from the occlusal/incisal surface to the bracket slot. Distal-end cutter. This instrument cuts the distal end of archwire while holding the cut end. Therefore, this can be used in an intraoral setting.
  19. 19. Mathieu plier. This is an instrument that locks (like a haemostat) and braces small metal parts. In general, they are used to hold and twist the ends of metal ligatures, and also to place elastic ligatures. Ligature-cutting plier. To avoid damage to the instrument, these pliers must only be used to cut small gauges of “dead soft” stainless steel ligature wire (<0.014”) intra orally. Hard wire cutter. This instrument is designed to cut thick wire (> 0.014”) extraorally.
  20. 20. Ladmore composite instrument. This non-stick instrument is used to place resin onto the base of the bracket. Cheek and lip retractor. This is an adjustable device that retracts away the lips and cheeks to maximize visibility and to minimize salivary contamination. Debonding plier. This instrument is used to remove brackets by holding the bracket mesio-distally and applying slight pressure by torquing or turning in a clockwise motion.
