Abstract

Introduction: Canines are the second most commonly impacted teeth. Treatment of an impacted canine is associated with demanding anchorage control, increased treatment duration, and undesirable side effects. Accurate localization of the impacted canine and force application impact the success of the treatment. The aim of the study was to determine the stresses on the palatally impacted canine (PIC) and on the adjacent teeth by Kilroy spring with an increase in degree of angulation (<30°, 30° −45°, >45°) using Finite element method. Materials and Methods: PICs with increase in horizontal impaction angulation with respect to the midlines underwent finite element modeling. A prototype 3D models were reconstructed and segmented into its anatomic components. Each PIC was precisely positioned according to impaction position. Von Mises stresses in response to 60 g of force were evaluated on the canine as well as on the adjacent teeth. Results: In all the three models, the highest stress was observed on the impacted canine with 60° angulation (0.62731 MPa). Canine showed the maximum von Mises stresses followed by lateral incisor and first premolar, respectively, in all the three models
