  27. 27. Pre-Adjusted Edgewise Appliance or The Straight Wire Appliance Larry Andrews - studied normal occlusion and individual tooth positions Developed prescriptions for individual tooth position Elements of “ideal” tooth position are built into the appliance Minimizing active “wire manipulation” The Straight Wire Concept www.indiandentalacademy.com
  28. 28. Pre-adjusted edgewise appliance First order / in-out - Horizontal plane Second order / tip - Mesio-distal angulation Third order / torque - Labio-lingual angulation 3 - Dimensional control of tooth position www.indiandentalacademy.com

  33. 33. Third order or Torque 4 To “Torque” is the least efficient tooth movement using orthodontic appliances www.indiandentalacademy.com
  34. 34. Significance of accurate bracket/band positioning Precise tooth positioning Optimal effect of “pre-adjustment” Occlusion Esthetics Stability www.indiandentalacademy.com
  35. 35. POSITIONING BRACKETS GENERAL INSTRUCTIONS Rhomboidal shape Disto-lingual wing mark Central scribe line (long axis) www.indiandentalacademy.com
  36. 36. Maxillary Central Incisors 4 4 • Distance from the slot to the incisal edge = 4mm • From the occlusal, the bracket is centered mesio-distally. • As a guide, approximate the incisal edge of the incisor with the base of the bracket perpendicular to the clinical crown long axis. www.indiandentalacademy.com
  37. 37. Maxillary Lateral Incisor Distance from the slot to the incisal edge • = 3.5mm 3.5 3.5 www.indiandentalacademy.com
  38. 38. Maxillary Cuspids • Distance from cusp tip to bracket slot = 4.5 mm • The severe angulation and prominent o anatomy of cuspids (10 ) can make placement difficult • 4.5 mm From the occlusal view, the bracket is centered mesio-distally on the prominent buccal developmental ridge. This also corresponds to the clinical crown long axis. This will usually be mesial to the center of the contacts 4.5 www.indiandentalacademy.com
  39. 39. Maxillary Bicuspids • Distance from cusp tip to bracket slot = 4 mm From the occlusal view, the bracket is centered mesio-distally on the prominent buccal developmental ridge. This also corresponds to the clinical crown long axis. www.indiandentalacademy.com

This notation numbers the teeth starting st nd with the central incisors as 1. The laterals are then 2. The canines are 3. The 1 and 2 st nd premolars are 4 and 5 respectively, the 1 molars are 6 and the 2 molars are 7. www.indiandentalacademy.com
