چکیده

Objective:

The aim of this study was to assess orthodontic mechanotherapy treatment effects on the prognosis of endodontically treated teeth.

Materials and Methods:

Ten

three-dimensional (3D) model for the four maxillary incisors and their related structure were constructed

; five of them have vital tooth property while the remining have the property for endodontically treated tooth. Five forms of tooth movements that involved through orthodontic mechanotherapy were simulated on each right central incisor: Intrusion (0.2 N), Extrusion, Rotation and, Tipping (0.6 N), and Translation (1.2 N).

Results:

The results show that the highest von mises stress was recorded within Translation movement for both vital and non-vital tooth within the highest value was recorded for vital teeth model (24.36 MPa). In general, in all orthodontic tooth movement for the four anterior teeth in both proposed condition the tension stress that have been recorded are higher than the compressive stress.

Conclusion

: Nativity and language preference interact to limit access to dental care. Spanish-When optimal force was maintained during orthodontic tooth movement, finite element study show that; for vital teeth only the Translation orthodontic tooth movement resulted in PDL compression stress higher than MTS suggesting ischemic and resorptive risks occurrence. While for non-vital teeth this risk appeared in both Rotation and Translation orthodontic tooth movement.
