COURSE CONTENTS:

Day 1 - Wednesday

10.00 General discussion of technical problems
Case conferences with quality document only
Revision of differential diagnosis, Treatment planning,
The 5 Treatment phases
Treatment for anterior protrusion cases with
open-bite vs. deep-bite cases

14.00 Lunch

Extraction Pattern

Max.1st premolars and Mand. 2nd premolars
Revision of the biomechanics for retraction of the anterior teeth
Control of the sagittal dimension

TYPODONT SET UP:

Get ready with your Typodont
Please set up your Typodont in a Class I malocclusion
Protrusion of the max. anterior teeth slightly crowding
Protrusion of the mand. anterior teeth
Slightly open-bite or edge to edge bite
In the class the teeth #14,24,35 and 45 will be extracted

18.00 Class finish

Day 2 - Thursday

Timing for extraction of the teeth 14, 24, 35 and 45 in growing child – The S.O.S.’s concept of serial extraction
The Side Effects in :

The leveling phase,
The movement phase and
The contraction phase

Wire Bending Exercise

UA 0.016 SS with canine curvature. How great should it be?
TPA 0.9 mm hard SS wire
