Tip edge technique /certified fixed orthodontic courses by Indian dental academy

  1. 1. Tip edge technique INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  2. 2. Contents • Introduction &Tip-Edge concept - Neelima • Differential Straight Arch Technique – Sameer • s • Stages of treatment • Final Finishing • Conclusion • References www.indiandentalacademy.com
  3. 3. Introduction Since the 1900 Angle introduced various appliances : • Angle’s E-arch • Pin and Tube appliance(1910) • Ribbon arch appliance (1915) • Edgewise appliance(1925) www.indiandentalacademy.com
  4. 4. Edgewise appliance • • • • • • Labially facing horizontal slot 3-dimensional control over tooth Very high forces were used Anchorage depends on extra oral forces No provision for closure of posterior spaces Arch wire slot restricts the anteroposterior correction of dental arches www.indiandentalacademy.com
  5. 5. Begg appliance During the early 1930s, P.R Begg reverted to the use of ribbon arch brackets• Permitted free tipping followed by controlled uprighting • Use of round wires • Use of differential forces(2 oz) • Demands on anchorage units was reduced However the vertically facing slot had the following limitations: – Hindrance in manipulation – Reduced mesio-distal control www.indiandentalacademy.com
  6. 6. Straight wire appliance • 1970s Dr Lawrence Andrews introduced the Straight Wire “bracket system” • Concept of Preadjusted applianceTip, torque, in-out compensations for each tooth was available. www.indiandentalacademy.com
  7. 7. Introduction of the concept of Tip-Edge • Limitations of conventional Straight Wire bracket – Moving teeth apex first generates maximum anchorage resistance – Torque control - unwanted reciprocal torque reaction in adjacent teeth – Full expression of torque not achieved- “torque slop” due to play between bracket and arch wire www.indiandentalacademy.com
  8. 8. Tip edge concept • Peter C Kesling decided to combine both the techniques • Modified a straight wire bracket ,to create Tip Edge bracket • Technique was first introduced at the Kesling-Rocke Orthodontic Centre,Westville,Indiana,USA in 1986. www.indiandentalacademy.com
  9. 9. • Differential force technique: initial crown tipping followed by controlled root uprighting with straight arch wires (differential tooth movement with straight arch wires). Therefore it is known as the “Differential straight arch technique” Arch wire slot permits initial crown tipping mesially or distally and faces horizontally, the slot and bracket are termed “TipEdge” www.indiandentalacademy.com
  10. 10. www.indiandentalacademy.com
  11. 11. Features of tip edge appliance • Labially facing arch wire slots –improved manipulation with elastomeric ties • Light forces(2 oz) • Reduced strain on anchorage • With a rectangular slot ,a 3-D control was afforded • Slots open and close during treatment for maximum ease of arch wire change and minimal discomfort • Facilitated intrusion of teeth. www.indiandentalacademy.com
  12. 12. Tip edge brackets Kesling determined that : • It is necessary for each tooth to tip either mesially or distally –not both directions • All teeth tip distally except those distal to the extraction sites-which tip mesially • Anchor molars should remain upright throughout Rx. www.indiandentalacademy.com
  13. 13. • Diagonally opposite corner were removed • Permits desired distal crown tipping • Preadjusted in 3 dimensionstip,torque,in & out built in • Slot size-0.022”x0.028” www.indiandentalacademy.com
  14. 14. Central ridge Lateral extensions Uprighting surface Tipping surface Profile view Occlusal view www.indiandentalacademy.com
  15. 15. Design features • Slot size: 0.022”X0.028” • Vertical slot: 0.020”x0.020”- to accept rotating or up righting springs, power pins ,jigs etc. Both the gingival and incisal ends are chamfered to facilitate the insertion of auxiliaries from either direction. • Lateral extensions- for rotational control hidden behind the arch wire –which is esthetic. • In and out compensation-eliminates the need for lateral, bicuspid or molar offset • Torque built in base • Tip built in face www.indiandentalacademy.com
  16. 16. • Slot permits initial M-D tipping ,this prevents bowing of arch wire during retraction/space closure and automatically enhances anchorage. • Uprighting surfaces of the slot determine the final tip angulations reached with an uprighting spring. These surfaces can also control torque if an edgewise arch wire is used. www.indiandentalacademy.com
  17. 17. Dynamic arch wire slot Tip edge slots become larger as the teeth tip. The vertical dimension within the slot continuously increases with each degree of distal tipping, eliminating binding &facilitates placement of A/W’s of larger cross sections. www.indiandentalacademy.com
  18. 18. www.indiandentalacademy.com
  19. 19. Advantages • No binding or archwire deflection during retraction • Ease of stepping up of archwire size • No inadvertent mesial or distal root movement • Ease of placing rectangular archwires when third order discrepancies exist between archwire and slot. • No need to use NiTi archwires to avoid discomfort and accidental debonding www.indiandentalacademy.com
  20. 20. Advantages of Tip Edge brackets • Over conventional edgewise brackets – Eliminates undesired force couples to promote rapid bite opening and prevent midline discrepancies – Anchorage problems are eliminated as space can be closed with light forces and minimum wire deflection. This results in diminished anchorage demands and increased vertical control. – Permits free crown tipping followed by controlled uprighting – Can reposition teeth and jaws with light forces and still maintain total control over their final positions. www.indiandentalacademy.com
  21. 21. Edgewise bracket Tip-Edge bracket www.indiandentalacademy.com
  22. 22. • Over Begg brackets – Horizontally facing archwire slots facilitate initial archwire engagement especially on rotated teeth. Elastomeric ties provide a cushion or flexibility that enhances patient comfort and reduces the chances for bond failure – In –out compensation eliminate the need for molar (or other) offsets. – Slot designs causes automotive shift from tipping to bodily movement at the predetermined angle and increase anterior anchorage to encourage mesial movement of posteriors – “Programmed Differential Mechanics” – Labio-lingual root torque from rectangular wires possible. www.indiandentalacademy.com
