Simulation of orthodontic tooth movement during activation of an innovative design of closing loop using the finite element method

•We simulated orthodontic tooth movement for correction of Class II Division 2 malocclusion.•A newly designed closing loop combined with a gable bend was studied.•A 5° gable bend produced lingual crown tipping of the central incisor.•A 10° bend produced bodily movement of central incisor and distal tipping of the first molar.•A 15° gable bend produced root movement of the central incisor.
