Transcript of "Deep bite /certified fixed orthodontic courses by Indian dental academy "

  1. 1. THE DEEP BITE- AN ORTHODONTIC ENIGMA INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  2. 2. THE DEEP BITE- AN ORTHODONTIC ENIGMA Bite opening a challenge Careful diagnosis and planning Biomechanical considerations Increasing emphasis on adult orthodontics Continuous arch mechanics may be frustrating! Requires a careful strategy www.indiandentalacademy.com
  3. 3. THE DEEP BITE- AN ORTHODONTIC ENIGMA In growing patients – Not advisable to intrude lower incisors Move posterior teeth to the level of incisors Incisor intrusion will affect vertical molar position affect facial aesthetics Depending on the severity upright molar/premolar segments or premolars www.indiandentalacademy.com
  4. 4. THE DEEP BITE- AN ORTHODONTIC ENIGMA In Adults Molar extrusion changes LAFH Not an advisable clinical procedure !! Incisor intrusion – a carefully planned solution An appropriate interincisal angle to prevent relapse www.indiandentalacademy.com
  5. 5. GENERAL PRINCIPLES Dissociate forces from moments, single point contact. Selection of point of force application and center of resistance of teeth to be intruded Control of posterior segment and reactive units Check anterior tooth geometry Extrude molars only in specific situations www.indiandentalacademy.com
  6. 6. Reverse curve of spee Ant teeth have nowhere to go except crown labial ,root lingual Round trip !! www.indiandentalacademy.com
  7. 7. Curve of Spee !! Only moments no net intrusive force www.indiandentalacademy.com
  8. 8. 2 couple system /indeterminate/minimal Intrusive force www.indiandentalacademy.com
  9. 9. Can you open a bite with a utility arch ? www.indiandentalacademy.com
  10. 10. One couple system,Off center V bend Extrusion in the shorter arm , Dissociation of moment and force www.indiandentalacademy.com
  11. 11. Single couple /determinate force system Precise application of force through center of resistance www.indiandentalacademy.com
  12. 12. www.indiandentalacademy.com
  13. 13. Precise force of 60 gms One point contact essential Precision essential to contain negative effects www.indiandentalacademy.com
  14. 14. For 2 central incisors-Cres on line parallel to mid sag plane pt on distal half of cuspid For 4 incisors – Cres projected line perpendicular to occlusal plane between canines and 1st bicuspids For 6 anteriors- Cres perpendicular to occlusal plane distal to 1st bicuspid www.indiandentalacademy.com
  15. 15. THREE PIECE INTRUSION ARCH 017x025 anterior segment in ss extension distal to lateral incisors tip back springs or cantilevers in 017 x025 tma calibrated for precise force www.indiandentalacademy.com
  16. 16. BIOMECHANICS-A REVIEW OF CONCEPTS Couple- pair of equal and opposite forces that produce a tendency for rotation called a moment www.indiandentalacademy.com
  17. 17. BIOMECHANICS-A REVIEW OF CONCEPTS Tooth movement is a net resultant of the equilibrium forces. The equilibrium is cognitive,not obvious and a source of surprise Tooth movement!! www.indiandentalacademy.com
  18. 18. LEVELING THE CURVE OF SPEE •Good growth increment – Buccal Segment Eruption •No Growth - incisor intrusion •3 Piece Intrusion Arch •Continuous Intrusion arches www.indiandentalacademy.com
  19. 19. Orthodontic force is 3-D www.indiandentalacademy.com
  20. 20. INCISOR INTRUSION Precision in direction and magnitude www.indiandentalacademy.com
  21. 21. www.indiandentalacademy.com
