“…On visual observation, the colour map of the NiTi closed‐coil spring simulation displayed a stress concentration localized over the impacted canine root in general, at the cervical level in particular, whereas the apical third of the root in the Kilroy spring simulation showed as blue that represents less amount of stress. This was found to be consistent with a previous study 10 that stated distal and buccal forces resulted with a greater stress than vertical forces at the apical third of the canine root and the higher stresses generated by the buccal force at the cervical level.…”

“…While there is a limited number of studies which investigated the effects of various orthodontic mechanics on impacted canine and surrounding tissues with FEM, 8,10 there is no study which investigated the stress distribution Kilroy and NiTi closed‐coil springs. Therefore, the purpose of our study was to compare and assess the stresses and initial displacements of the canine and adjacent teeth caused by the Kilroy and NiTi closed‐coil springs.…”

“…A previously published study that aimed to evaluate the stresses on the impacted canine in which the initial force was applied in different directions also supports the aforementioned idea. The authors concluded that stresses varied with different force directions 10. The stress amount on the impacted canine and the adjacent teeth was almost twice as high for the Kilroy spring simulation compared to the NiTi closed-coil spring.…”

“…FEM is frequently preferred to be able to compare different biomechanical characteristics under standard conditions by eliminating individual differences in assessment of biomechanical principles. 9 While there is a limited number of studies which investigated the effects of various orthodontic mechanics on impacted canine and surrounding tissues with FEM, 8,10 there is no study which investigated the stress distribution Kilroy and NiTi closed-coil springs.…”

Maxillary canines are the most frequently encountered impacted teeth after the third molars, while the impaction rate varies in the range of 0.8%-2% based on ethnic variations. The canines are palatally impacted in 85% of patients and labially or buccally impacted in 15%. 1 Ideal alignment of the impacted canine teeth with a successful orthodontic treatment is dependent on the surgical procedure, individual variations, and determining the exact position of the impacted tooth and also its relationship with neighbouring teeth. Biomechanical properties such as the amount of force, the application point and direction of the force are highly important to achieve
