چکیده
Abstract:
 Objectives: This work aimed to determine the stress distribution around a mini-implant during dynamic canine retraction utilizing continuous and intermittent orthodontic forces three-dimensional finite element model.
 Materials Methods: Establishing model of retraction. The incorporates mini-implant, alveolar bone, maxillary teeth, closed coil spring, an elastic chain. They were described as being homogeneous, isotropic, linear elastic. Continuous interrupted approximated by NiTi spring chain, respectively. To retract canine, simulated force 1.5N, 2N, 2.5N loaded. ANSYS evaluated value bone interface (workbench 19).
 Results indicated that there was no significant difference between values maximum miniscrew, under different loads when chain evaluated.

Finite element analysis of maxillary incisor displacement during en-masse retraction according to orthodontic mini-implant position
OBJECTIVE Orthodontic mini-implants (OMI) generate various horizontal and vertical force vectors and moments according to their insertion positions. This study aimed to help select ideal biomechanics during maxillary incisor retraction by varying the length in the anterior retraction hook (ARH) and OMI position. METHODS Two extraction models were constructed to analyze the three-dimentional f...
