BIOMECHANICS IN THE USAGE OF EXTRA-ALVEOLARS MINI-IMPLANTS One of the most important aspects when using extra-alveolar mini-implants is applying the best force system.

by definition, are the biomechanical concepts critical for understanding treatment of numerous issues, regarding force systems and the resultant force for a required motion.

the importance of understanding the force-moment, its magnitude, direction and duration, point of application and prediction of center of resistance, center of rotation, differential moment, etc. The requirements for a clinical application consistent with Biomechanics include basic information that are necessary for understanding the physics principles that are common to every orthodontic equipment.

with finite elements (3D) study, in order

to determine the correct stress in the periodontal ligament (determinate mechanics)

. In this manner, with the intention of simplifying the application of Biomechanics concepts for treating complex malocclusions, instead of segmented mechanics and utilizing the numerous accessory devices from the segmented arch's classical

technique, it is possible to apply multivector mechanics provided by a sophisticated force system using extra-alveolar mini-implants.

Thus, the biomechanics principles (force systems) applied for the use of extra-alveolar miniimplants will be detailed further ahead.
