Biomechanics- Basic Principles

The physical concepts that form the foundation of orthodontic mechanics are the key to understanding how orthodontic appliances work and are critical in designing treatment methodologies and appliances. Mechanics is a branch of physics that deals with mechanical properties and when this knowledge and methods of mechanics are applied to the structure and function of living systems i.e. biology-for example, a tooth and its surrounding oral architecture-it is called biomechanics. The basics of biomechanics include force and moment, center of mass, center of gravity, center of resistance, center of rotation, moment to force ratio, and other related terminologies.

Dr. kindly, how can a crimpable hook move the teeth if it was put at the mid point between 2 brackets and not attached or so close to it, I mean, how can it move teeth if it wasn't fixed to the bracket?
Can you please explain this point.

Complex details made easy. Thanks Doctor

Hi Dr. What's up?
please.. can you tell us about..
1_ what is meant by low and high torque bracket, and in what cases we can use them?
2_ how can we prevent the wagon wheel effect, when a torque is applied to the anterior teeth especially the laterals, and if happend, how can we fix it?
thank you so much 🙏🌹

Very well explained
