QUALITY RESULTS
5. Key Objective
Patient ends up with the face proportionately
balanced and consistent with his skeletal pattern .
The treatment should be completed in the stipulated
time with a satisfied patient, parent and doctor
6. Unique Concepts.
1.First Straight wire type –
Different designs of brackets in the same
case, depending on the type of teeth.
The – 5 degree lower anterior torque is
different from other appliances.
2. Only 2 to 3 arch wires to be changed
7. 3. Bracket design and bracket effectiveness
does not dictate the treatment technique.
4. Rectangular multistranded arch wires
8. DIAGNOSIS AND TREATMENT PLANNING
.
Patient information
Diagnostic Chart
Patient records
Cephalometrics , patient
examination
Treatment planning
Financial records
12. Critical Factor in diagnosis
Lower Incisor Position.
1.Incisor mandibular plane angle.
2.Holdaway Ratio.
3.Lower incisor to A-Pog
13. Treatment Plan.
Two steps:
1.Determine the desired position of the
mandibular incisor.
2.Determine the treatment needed to position
the maxilla and maxillary dentition over the
desired mandibular arch position.
14. Objective of Treatment:
1.Incisors upright over the basal bone .
2.Cuspids not expanded.
3.Level curve of spee.
4.Non extraction therapy .
15. VARI-SIMPLEX DESIGN
Brackets are
• Pretorqued
• Preangulated
• Built in In / Out
[Pioneered by IVAN LEE and LARY ANDREWS]
Different bracket design on particular teeth in the arch,but
the system of brackets for each pt is identical.
16. IMPORTANT FACTORS IN DETERMINING
THE DESIGN OF THE V.S.APPLIANCE
1. Shape and Size of the tooth.
Mesiodistal width and curvature.
2. Accessibility.
3. Patient comfort and frequency of bracket wing
breakage.
17. Factors Related To The Brackets
1. Bracket selection
2. Bracket placement
3. Bracket angulation
4. Bracket torque
5. In / Out
26. OTHER ATTACHMENTS
•Twin bracket with a Convertible sheath .
•Head gear tubes placed occlusally*.
•15 degree offset –upper first molar .
5 degree – mandibular first molar.
•Ball hooks .
27. OTHER ATTACHMENTS
• Single buccal tubes second molars
• 6 degree distal offset built in the lower second
molar.
• Lingual hooks on all molar bands.
Appliance does not dictate the treatment technique
29. Bracket angulation
• Ideal axial inclination.
Roots parallel Crown in most esthetic
&functional position.

VERTICAL LINES PARALLEL TO THE
LONG AXIS OF THE TOOTH
32. Dr Dwayne Trammell
BAYLOR UNIVERSITY
• Laminographic x- ray of the molars
• 3 months
• Superimposition showed
Root tips moved
anteriorly by , 0.5
mm
Crowns tipped distally on
an average of 1mm
• 2 mm of arch length
35. DR. TRAMELL
• Class II non extraction cases
• 0.017’’ x .025’’ D RECT MULTISTRANDED -
3 MONTHS
• Superimposition showed incisal edges moved
lingually by less than 0.5mm
• Root apices moved labially on an average of 1mm
• Main aim Hold the incisors in its
original position
48. Elastics in Vari – simplex
discipline
• To align the maxillary dentition with the
mandibular dentition and correcting an
centric occlusion / centric relation
discrepancy.
• Correction of cross bite and midline
• Finalize the occlusion
3 to 6 ounces
61. Borderline Non extraction
• Negative torque on the lower incisors
bracket
• Negative tip on the lower molar bracket
• Flexible D RECT wire initial
• Bonding instead of banding
• Ability to perform selective interproximal
reduction

DEEP BITE CASES
• Bite plate.
• Cervical retractor
65. CLASS III CASES
• Start treatment in both arches.
• Early use of class III elastics.
• Extra oral forces.
OPEN BITE
• Bracket positioning.
• Extra oral forces
67. Advantages of delaying treatment in
the mandibular arch:
1.Physiologic drifting. ‘DRIFTODONTICS’
68. 2. No interference for retraction of
maxillary canines .
3. Additional time for second molars to
erupt.
