Protraction headgear for class 3 correction /certified fixed orthodontic courses by Indian dental academy

  1. 1. ORTHOPEDIC CORRECTION OF CLASS III USING PROTRACTION HEADGEAR www.indiandentalacademy.com INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com
  2. 2. ORTHOPEDIC CORRECTION OF SKELETAL CLASS III USING PROTRACTION HEADGEAR www.indiandentalacademy.com
  3. 3. INTRODUCTION www.indiandentalacademy.com
  4. 4.  One of the most perplexing malocclusion to diagnose and treat is class III malocclusion particularly in mixed and late deciduous dentition  Timing of ortho treatment has always been controversial www.indiandentalacademy.com
  5. 5.  Even today many class III cases are not treated until orthodontist feels that active growth is complete  Purpose here is to emphasize the need for early diagnosis and possible treatment for class III and their associated facial patterns www.indiandentalacademy.com
  6. 6. COMPONENTS OF CLASS III www.indiandentalacademy.com
  7. 7.  Normal mandible and retrognathic maxilla IN SAGITTAL DIRECTION www.indiandentalacademy.com
  8. 8. IN SAGITTAL DIRECTION  Normal maxilla and prognathic mandible www.indiandentalacademy.com
  9. 9. IN SAGITTAL DIRECTION  Retrognathic maxilla and prognathic mandible www.indiandentalacademy.com
  10. 10. MAXILLARY DEFICIENCY Maxillary deficiency can involve all 3 planes of space  Transverse  Vertical  Horizontal www.indiandentalacademy.com
  11. 11. Usually the deficiency is more common in one of 2 planes …….. A primary transverse deficiency with horizontal & particularly vertical dimension less effected www.indiandentalacademy.com
  12. 12. • A horizontal & vertical deficiency with reasonably normal transverse dimension www.indiandentalacademy.com
  13. 13. TRANSVERSE DIMENSION Opening of mid palatal suture should provide a way to widen narrow maxilla . The age of patient is a factor for obtaining separation of sutures www.indiandentalacademy.com
  14. 14. • Most of the times the use of protraction headgear for correction of maxillary deficiency is accompanied by palatal expansion using any of the expansion appliances. www.indiandentalacademy.com
  15. 15. HORIZONTAL-VERTICAL DEFICIENCY • If the normal headgear force compresses the maxillary sutures to inhibit the froward growth of maxilla. so the reverse pull headgear by separating the sutures stimulates the growth. www.indiandentalacademy.com
  16. 16. VERTICAL DEFICIENCY  Maxillary deficiency in vertical plane causes auto rotation of mandible leading to class III www.indiandentalacademy.com
  17. 17. • As the reverse pull headgear applies a force to mandible ,a downward & backward rotation of mandible usually takes place which is also 1 of the factors for improvement of class III relationships www.indiandentalacademy.com
  18. 18. Effects of forward traction against the maxilla www.indiandentalacademy.com
  19. 19. RESPONSE TO FACE MASK SHOWING THE DOWNWARD &BACKWARD ROTATION OF MANDIBLE www.indiandentalacademy.com
  20. 20. DIAGNOSIS “IT IS ONLY WITH THE BRAIN THAT ONE SEES RIGHTLY. WHAT IS ESSENTIAL, IS INVISIBLE TO THE EYE”www.indiandentalacademy.com
  21. 21.  Positive and negative characters are developed as guidelines for deciding whether to intercept class III or not Positive characters-indicates early interception Negative characters-indicates that the case is not appropriate for interception www.indiandentalacademy.com
  22. 22. Convergent facial type  Antero-posterior functional shift  Symmetrical condylar growth with growth remaining  Mild skeletal disharmony ANB<-2  Good co operation expected  No familial prognathism  Good facial aesthetics POSITIVE CHARACTERS www.indiandentalacademy.com
  23. 23. NEGATIVE CHARACTERS  Divergent facial type  No antero-posterior shift  Poor facial aesthetics  Familial pattern established  Severe skeletal disharmony ANB >-2  Poor co operation www.indiandentalacademy.com
  24. 24. APPLIANCE OF CHOICE “MAKE SURE YOU ARE RIGHT & THEN GO AHEAD” www.indiandentalacademy.com
  25. 25.  MIXED DENTITION  FR-3  Orthopedic chin cup  Orthopedic face mask  LATE PERMANENT DENTITION  Orthognathic surgery  Camouflage treatmentwww.indiandentalacademy.com

  43. 43.  Of all the treatment modalities in mixed dentition it is our opinion that the orthopedic face mask has widest application and produces the most dramatic results in shortest period of time www.indiandentalacademy.com
  44. 44. ONE SHOULD FOLLOW THE PHILOSOPHY OF….. “SELECTING AN APPLIANCE FOR THE PATIENT NOT A PATIENT FOR APPLIANCE” ” www.indiandentalacademy.com
  45. 45. CONCLUSION www.indiandentalacademy.com
  46. 46. • Early Orthodontic treatment can be very rewarding if we are ready to accept the challenge of anticipating the changes associated with facial growth and development and patient response, with a sound problem list and treatment goals. www.indiandentalacademy.com
