Must be a practicing dentist and or orthodontic resident/graduate student in any graduate Orthodontic program.
The objectives of this course are :
1 To provide the orthodontic graduate students with an introduction to the biology of orthodontic toot movement.
2 To provide the students with the required understanding of the basic biomechanics and its application in clinical orthodontics.
3 This course also will provide an introduction to the segmented arch mechanics as well as to Wilson 3D appliances and how their basic mechanics could be applied.
4 This course will provide the students with the required hand skills in wire bending and how to control tooth movement using standard edgewise technique in the lab (Using the lab manual and typodont).

Dr. Tarek El-Bialy is a tenured full time professor of orthodontics and biomedical engineering at the University of Alberta, Canada. He received a BDS from Tanta University, Egypt in 1987 and completed a Master’s degree in Orthodontics, at Tanta University, Egypt; in 1993 concurrently he received a law degree from Tanta University in 1994. He has successfully completed a certificate of specialty in Orthodontics, Master’s Degree in Oral Sciences and PhD in Bioengineering at the University of Illinois at Chicago, USA in 2000 and 2001. Also, he completed Executive Masters of Business and Administration (EMBA) at the University of Alberta in 2012. A significant part of Dr. El-Bialy’s work was devoted to growth modification and repair of orthodontically induced root resorption. Dr. El-Bialy is a fellow of the Royal College of Dentists of Canada (RCDC) and Diplomat of the American Board of Orthodontics. Also, he is a senior research fellow, von Humboldt Foundation, Germany since 2013. He also is a Councilor of orthodontics at the RCDC council. In addition, he has been elected by the University of Alberta General Faculties Council as a representative to the University of Alberta Senate. Dr. El-Bialy is the current president of the Alberta Society of Orthodontists. Dr. El-Bialy has over 84 peer reviewed publications, 12 book chapters and two books, one of them on biomechanics of complex cases using clear aligners. He also presented all over the world on one week aligners change and biomechanics of difficult cases using SmartTrack Invisalign aligners. Dr. El-Bialy’s main research focus is on low intensity pulsed ultrasound in orthodontics and dentofacial tissue engineering.
