Teeth movement prediction. Force systems

– Force and components producing forces

– Mathematics in orthodontics:

- Angle of application of force, line of action of force, point of application of force

- Calculations in 2D and 3D coordinate systems

- Horizontal and vertical force components

- Summing up the effects of two forces: rules

- Calculation of the angle of the force vector.

– An example of calculating forces when moving a molar

– Analysis of dental movement by calculating vectors

– The tendency to rotation: prerequisites

– The couple of forces: definition and calculation

– Creating a moment of force in the braces

– Dental movement: the relationship between movement and the force system

– Qualitative analysis of the purity of forces

– The concept of the center of resistance

– Types of dental movement: translation, pure rotation, central rotation

– Method of calculating the geometric center of rotation

– Calculation of the distance between the center of resistance and the center of rotation.
