Biomechanics in Orthodontics (Bio)-1: Quick Revision with UIC
These are highlights from the webinar with UIC, Orthodontics on May 6th 2020 by Madhur Upadhyay. It is a quick rundown of Biomechanics in Orthodontics (Bio) -1 course held in August/September 2019 at University of Illinois, Chicago USA. Bio-1 course is an extensive 40+ hours of didactic/problem solving based education conducted via live sessions of 3-5 hrs each. Please note this talk does not include many of the key concepts critical for understanding higher concepts of tooth movement.

Biomechanics of Clear Aligners: Hidden Truths & First Principles
This is a summary commentary of a paper published in Journal of the World Federation of Orthodontists ( Volume 11, Issue 1, February 2022, Pages 12-21) by Madhur Upadhyay & Sarah Abu Arqub. It utilizes ‘first principles’ and the existing evidence to unravel some of the key drawbacks of aligner-based therapy. Several shortcomings in the biomechanical properties of aligner material (thermoplastics) that affect clinical performance are discussed. This paper provides clinical insights for improving predictability and effectiveness of aligner therapy.
