  • 16. 16 Pentamorphic Arch Forms www.indiandentalacademy.com
  • 17. 17 Finishing and Retention www.indiandentalacademy.com
  • 18. 18 Finishing and Retention  ―Begin with the end in mind‖.  Every orthodontist has a visual picture in his mind of the ideal occlusion into which the teeth should fit and mesh in the final finished occlusion. www.indiandentalacademy.com
  • 19. 19 Finishing and Retention  Bioprogressive proposes the concept overtreatment….  No clinician can position teeth as delicately as the functioning incline plane and cusp action can accomplish naturally when it is adequately set up to operate correctly.  Allow natural function to guide the teeth into the best functioning occlusion for each individual www.indiandentalacademy.com
  • 20. 20 Finishing and Retention www.indiandentalacademy.com
  • 21. 21 Finishing and Retention  Two phases of retention: 1. Guiding changes during initial adjustments. 2. Supporting bony sutural and muscular accommodations to changing environment and considering long range influences. www.indiandentalacademy.com
  • 22. 22 Finishing and Retention  Initial stage of retention :  First six weeks following appliance removal  Retainers inserted-designed not to hold but to guide the teeth in settling. www.indiandentalacademy.com
  • 23. 23 Finishing and Retention Labial frame of typical upper retainer (Ricketts) passes between the lateral and cuspid and has a distal loop at each end to tuck in the distal of the expanded overtreated upper cuspid www.indiandentalacademy.com
  • 24. 24 Finishing and Retention  Lower arch:  Fixed first bicuspid retainer is placed. -maintain cross arch bicuspid width. -lower cuspid freedom of adjustment against upper occlusion. -maintain lower incisor alignment and rotation correction. www.indiandentalacademy.com
  • 25. 25 Finishing and Retention  Stabilizing stage of retention:  First year following active treatment.  Lower retainer is kept in place and upper is worn most of the time. www.indiandentalacademy.com
  • 26. 26 Bioprogressive Simplified James J. Hilgers Jco 1987-part 1-4 www.indiandentalacademy.com
  • 27. 27  Translating orthodontic skills into a bona fide delivery system is one of the most difficult tasks faced by clinicians.  The best orthodontic managers are able to identify the necessary information and leave out the extraneous.  ―After studying many treatment disciplines, I chose the Bioprogressive approach because it was flexible‖. www.indiandentalacademy.com
  • 28. 28 Visual Treatment Objective  Orthodontic movements are more significant than growth changes  The VTO leads the clinician toward a viable treatment plan by organizing factors The superimpositions that define the practical part of the mechanical procedures www.indiandentalacademy.com
  • 29. 29  An accurate measurement of arch length deficiency— combined with the clinician's judgment of dental and facial changes required— is used in the simplified VTO to produce a reasonable treatment goal www.indiandentalacademy.com
  • 30. 30 Occlusal Paralleling Instrument  Arch length deficiency is one of the most critical aspects of diagnosis.  One of the most accurate measuring devices is the mandibular occlusal x- ray www.indiandentalacademy.com
  • 31. 31 Diagnostic procedures  Grades the patient as- A- enthusiastic B- average C- resistant  Patient assurance about headgear usage. www.indiandentalacademy.com
  • 32. 32 Appliance design  End-of-treatment goals should be dynamic, not based on statistical norms.  This kind of overcorrected result can be called an ideal orthodontic occlusion— one that will settle after positioner treatment, retention, and normal physiologic rebound into an ideal occlusion and thereafter into a normal occlusion www.indiandentalacademy.com
  • 33. 33 Appliance design 1. Type and severity of the original malocclusion. 2. General approach to mechanics. 3. Size of the final arches. 4. Timing of torque control 5. Bracket placement and design. www.indiandentalacademy.com
  • 34. 34 Appliance design  Linear Dynamic system designed by the Ormco 1979.  17-4 grade of stainless steel, which has more than three times the yield strength of the standard 303 grade  30% smaller bracket that is stronger than its full-size counterpart.  20% size reduction in molar region. www.indiandentalacademy.com
  • 35. 35 Appliance design The key to a Class I buccal segment is the proper positioning of the lower first molars www.indiandentalacademy.com
  • 36. 36 Linear Dynamic System  Ideal orthodontic tooth position.  Anticipated rebound and required overcorrection.  Appliance design features that contribute to patient comfort, clinical simplicity, and optimum utility. www.indiandentalacademy.com

  • 43. 43 Extraction Therapy  Upper arch  Upper arch-depends on the position of the incisors a) Good position-16 x16 vertical closing helical loop. b) Need to be engaged at the onset of the treatment-0.16 round overlay wire. www.indiandentalacademy.com
  • 44. 44 Extraction Therapy  Traction and final cuspid space closure  Cuspids have almost retracted and bite has opened sufficiently-traction arches are placed.(17x 25 NiTi or TMA) 1. Allow final incisor alignment 2. Correct details of the arch form 3. Allow for final root paralleling ,torquing in cuspid and bicuspid region. www.indiandentalacademy.com
  • 45. 45www.indiandentalacademy.com
  • 46. 46 Extraction Therapy  Consolidation  This is done achievement of good arch form.  Lower retraction-1 or 2 month ahead. -16 square helical continuous closing arch.  Upper retraction- - if they are proclined with no torque requirement -016 round wire www.indiandentalacademy.com
  • 47. 47 Extraction Therapy -if in good relation-16 square or 16 x 22 closing loop -if additional torque is needed –retraction utility is used. -if ant intrusion and post extrusion – combination crossed ―T‖ horizontal closing loop is used. www.indiandentalacademy.com
