May 16, 2021

Faculty: Dentistry
Department: Dentistry
Type of the workshop: International Workshop
The workshop in brief:

The workshop covered the basis of biomechanics and tooth movements, with a highly practical and clinical approach. In-depth teaching on more complex tooth movements and appliances, as well as the clinical application of biomechanics to the most used straight-wire techniques, compared with the new i-arch approach.


  • To enable the participants to identify and understand various biomechanical principles.
  • To enable the participants to understand how to apply various principles to their appliance.
  • To enable the participants to understand how to create desired and predictable tooth movements.
  • To enable the participants to understand efficient biomechanics to achieve effective results in a variety of patients.
  • To enable the participants to understand the archwires sequence comparing Traditional Vs. i-Arch approach.
  • To enable the participants to debate clinical case.

Number of participants: 90 participants from the academic staff of Dentistry Faculty – TIU, Orthodontics postgraduate students of Hawler Medical University, in addition to some specialist dentists from other different universities participated in the workshop.

Date and time: May 19,  2021. 14:00
Place:  Tishk International University – Dentistry Faculty building.

Session topics: 

  • First Session: Introducing and discussing the basis of biomechanics and tooth movements by Prof. Dr. Giovanna Perrotti.
  • Second Session: Explaining archwires sequence and comparing Traditional Vs. i-Arch approach by Dr. Omar Sabah.
  • Third Session: Hands-on training regarding i-arch system applications and biomechanics.

Presenters names and affiliations:

  • Prof. Dr. Giovanna Perrotti (Head of Department of orthodontic and pediatric Dentistry) the University of Milan.
  • Dr. Omar Sabah (Head of Orthodontic department ) Tishk International University.

Outcome of the workshop:

The workshop simplified force systems to address any type of tooth movement necessary, because in orthodontics ‘tooth movement’ has always been the name of the game. Numerous cases and hands-on exercises, including wire bending and typodont exercises, were used to demonstrate various aspects of these ‘simplified common sense mechanics’.
