ADULT TREATMENT AND REVISION OF THE PREVIOUSLY TAUGHT PRINCIPLES OF THE EDGEWISE TECHNIQUE
COURSE CONTENTS:
Day 1 Wednesday
10.00 General Discussion of any problems
Case consultation. Diagnosis & Treatment planning
12.30 – 14.00 Lunch
Day 1 Wednesday
14.00 Revision of Differential diagnosis & Diagnosis Protocol
Clinical diagnosis: What is 4 T in 4 D?
I. Hard Tissue (Skeletal pattern)
II. Soft Tissue and
III. Teeth
IV. TMJ
Treatment Planning in Adult vs. in Children
Orthopedic effects
Headgear effects in Adult. What about TPA?
Extraction vs. Stripping in Adult
Extraction pattern and timing in Adult vs. in Children
Expansion Techniques
Bone Biology
Periodontal considerations
Pre-orthodontic Scaling and Periodontal Tx
Plaque control during orthodontic Tx
Supragingival plaque and Subgingival plaque
Post-orthodontic Deep-Scaling
Side Effects in adult Tx :
Gingival Recession and the Black Triangle
Conduction of the Tx in a periodontally involved case
The inform consent

Conclusion:
Mechanotherapy for Class I, Class II & Class III Tx
Technical revision for
Adult with Tooth Lost :
Space opening or maintaining or Closing
Space Opening:
Coil spring,
0.016” x 0.016” SS or 0.016×0.022TMA & SS Multiple
Expansion Loops
How to use the Key?
The mandibular incisor position
The maxillary incisor position
Inter-incisal Angle
Retraction of max. anterior teeth – Retraction Technique
Torque control in the anterior segment
Up-righting of the molars: Technical and side effect
Wire bending at the extraction site – Banding

TYPODONT SET UP
Please set up your Typodont in Class I Molar relationship with
anterior crowding of both arches
Deep over-bite, Unilateral high canine eruption (not too high),
#35 or # 45 are partially embedded. Band all 2nd molars
One of the mandibular molar may lost and the mandibular M2 is
mesially tipped and space loss

Wire bending Exercise
0.016” SS vs. TMA leveling arch wire

18.00 Class finish

Day 2 Thursday

10.00 Biomechanics for Deep-bite and Open bite cases ( Revision )
Bite opening & bite closing Technique
“Wedging Effect”
Case Demonstration Non-Extraction, Decrowding Technique &
Free the mandible with Maxillary Bite plate

12.30 – 14.00 Lunch

14.00 0.016” x 0.016” SS Intermediate AW
(or 0.016” x 0.022” TMA) with intrusion/extrusion steps
(or 0.016” x 0.016” SS contraction arch wire)
Midline Correction with 0.016” x 0.022” SS with 3 contraction
loops AW
0.016” x 0.022” or 0.017” x 0.022” SS contraction AW
Conclusion:
Biomechanics for open-bite cases ( Revision ) &
Vertical control by extraction for bite closure:

Class I canine and Canine guidance
4. Marginal ridge relationship leveled & Midline
Correction
5. Stripping and selective grinding
6. Over-correction
