Moment to Force Ratio in Orthodontics (Video)
In orthodontics, we move teeth by applying simple forces and moments. A ratio exists that determines if the tooth will translate more or rotate more. In this short video, we introduce the concept of the moment of force ratio. https://youtu.be/g512MYinVXU [...]
Aligner and Tooth Movement (Video)
Sometimes using aligners appear to be the solution to move teeth effectively. It is true in certain situations but others present specific challenges. The following video presents a potential solution to the problem of rotating and translating a tooth with aligners. https://youtu.be/GP885NA9zwc [...]
The Edgewise Bracket (Video)
Some historical perspective on the edgewise bracket. I am not entirely sure that the chronology is correct. It is of interest to see that Dr. Angle's invention of the edgewise bracket still is in use with modifications to this day. This free lecture is part of the IFDE biomechanical module 2 soon to be offered online. In the course, we will study the biomechanical concepts introduced by Dr. Burstone, Dr. Andrews, and others, to build a sound biomechanical perspective. We will add more webinars t [...]
Orthodontic Bracketing Introduction (Video)
A method to bracket the maxillary arch using the straight wire system. Tips and tricks to improve the bracketing process, decrease wire bending, and get the best outcome possible. [...]
Orthodontic Bracketing Introduction: Central Incisors (Video)
Bracketing is one of the most important steps in the orthodontic treatment. This important step is sometimes overlooked and may result in less predictable outcomes, as well as an increase in the duration of treatment as teeth may not be aligned, even if the wires are straight. The following video illustrates one method to bracket the upper incisor. [...]
Best Oral Presentation Award
Last week I had the privilege of being a judge for the Orthodontics Mastery Group's first Resident Best Oral Presentation competition. 34 applicants submitted their applications, and 8 were selected to present. Dr. Mohamed Nur Abdallah, one of my good friends, won the prize representing Canada. I was very happy for him but even more so for the organizers who masterfully organized this event. -Dr. Jean-Marc Retrouvey [...]
Orthodontic Biomechanics and Open Bite (Video)
Dr. Almuzian During the Pandemic, I was asked by Dr. Almuzian to present two webinars for his Orthodontics Mastery Group, an orthodontic evidence-based discussion group for specialist orthodontists, postgraduate orthodontic students, and orthodontic residents. I presented a Webinar on Biomechanics (Biomechanics Approach of a Sample of Open Bite Malocclusions) and on Open Bite. The webinars reached over 1000 orthodontists and it was a privilege to share the stage with such prominent and gen [...]
