Abstract
Abstract
Objective
This study aims to evaluate the stress distribution and displacement that result from the use of the isoglide eruption spring during palataly impacted canine traction using three-dimensional finite element analysis.
Materials and methods: A three-dimensional finite element model of the maxilla was developed from a scanned dry model of skull (meditT510). Traction was simulated
With the isoglide eruption spring which is made of nickel titanium (1.2 N). Von Mises stress distributions and initial displacements of the palataly impacted canine and adjacent teeth were analyzed.
Results: The isoglide spring showed 0.293MPa stresses on the palataly impacted canine. The stress distribution decreased as the distance from the impacted canine increased. The stresses were (0.225MPa) on the adjacent lateral incisor and (0.002MPa) on the first premolar. The isoglide spring showed a total displacement of (0.0002 mm) on the impacted canine.
Conclusion: The iso glide eruption spring is efficient in traction of palatally impacted canines with the stresses on the neighboring teeth decreased as the distance from the impacted canine increased .
