Training program

Day 1

Theoretical part

10:00 - 13:30

Introduction to orthodontic biomechanics
- Optimal forces needed for tooth movement
- The force versus the centre of resistance

- The moment of force
- The moment of force to moment of couple ratio

- The centre of rotation
- Types of tooth movements depending on the centre of rotation
- Force systems in orthodontics: determinate one-couple systems, and
non-determinate two-couple systems

- Biomechanics of the simple lever

- Biomechanics of V bends

- Biomechanics of step bends
Indications for early orthodontic treatment
Methods of treating eruption disorders: impacted baby teeth, supernumerary teeth,
reinclusion, ectopic eruption, impacted teeth (incisors, canine teeth, molars),
transposition, primary eruption disorders – aetiology, orthodontic – surgical
therapeutic protocols and biomechanics of impacted tooth extrusion
(“piggyback” technique, vertical and horizontal simple lever,
ballista spring, extrusion and intrusion arches, micro implants).
Methods of treating transverse disturbances
- Transverse maxillary hypoplasia: assessment of the skeletal disproportion and
maturity of the mid-palatal suture, removable plate expander with a screw, bi-helix,
NiTi expander, expander with a hyrax screw
- Crossbites caused by tooth positioning: mechanics of the bend out and toe in
bending - expansion arch with V-type bends, trans-palatal arches, NiTi expander,
biomechanics of intermaxillary tractions, micro implants
- Suspended bites caused by tooth positioning: removable plate expander with a
screw, mechanics of the bend out and toe in bending – contraction arch with V-type
bends, expansion arch with V-type bends, biomechanics of intermaxillary tractions,
micro implants
