  • FIXED ORTHODONTIC APPLIANCES www.indiandentalacademy.com
  • INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  • Removable vs. Fixed Appliances REMOVABLE Tipping only No control over root movement Pt’s co-operation Hygienic FIXED Bodily translation Control of root movement Less dependent on pt’s co-op Less hygienic www.indiandentalacademy.com
  • DEVELOPMENT OF FIXED ORTHODONTIC APPLIANCES www.indiandentalacademy.com
  • Development of Fixed appliances Early fixed appliances Late 1800s Edward Angle www.indiandentalacademy.com
  • EARLY FIXED APPLIANCES www.indiandentalacademy.com
  • Development of Fixed appliances Standard Edgewise appliance Early 1900s www.indiandentalacademy.com
  • Development of Fixed appliances Pre-adjusted edgewise appliance 1970s Refined manufacturing process with “builtin” adjustments specific for each tooth Advances in material sciences made attachment much smaller www.indiandentalacademy.com

  • Components of the Fixed Appliance Bands Molar Tubes Brackets Arch Wires Auxiliaries: Elastomeric products, Coil springs, Lingual arches, Extra-oral appliances www.indiandentalacademy.com
  • ARCH WIRES Maxillary and mandibular Arch form described as “parabolic shaped” Size and cross-section of wires vary Material varies eg. Nickel Titanium alloy (NiTi), Titanium Molybdenum Alloy (TMA), Stainless Steel www.indiandentalacademy.com

  • Elastics www.indiandentalacademy.com
  • EXTRA ORAL FORCES - HEAD GEAR www.indiandentalacademy.com
  • Coil Spring Closed or open coil springs www.indiandentalacademy.com
  • 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
  • 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
  • First order or In-out www.indiandentalacademy.com
  • Pre-adjusted edgewise appliance First order / in-out - Horizontal plane Second order / tip - Mesio-distal angulation Third order / torque - Labio-lingual angulation www.indiandentalacademy.com
  • Second order or Tip 4 www.indiandentalacademy.com
  • Pre-adjusted edgewise appliance First order / in-out - Horizontal plane Second order / tip - Mesio-distal angulation Third order / torque - Labio-lingual angulation www.indiandentalacademy.com
  • Third order or Torque 4 To “Torque” is the least efficient tooth movement using orthodontic appliances www.indiandentalacademy.com
  • Significance of accurate bracket/band positioning Precise tooth positioning Optimal effect of “pre-adjustment” Occlusion Esthetics Stability www.indiandentalacademy.com
  • POSITIONING BRACKETS GENERAL INSTRUCTIONS Rhomboidal shape Disto-lingual wing mark Central scribe line (long axis) www.indiandentalacademy.com
  • 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
  • Maxillary Lateral Incisor Distance from the slot to the incisal edge • = 3.5mm 3.5 3.5 www.indiandentalacademy.com
  • 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
  • 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
