Abstract

Introduction: Deep bite is common finding in different malocclusions and it is frequently treated by intrusion of incisors. This creates stress areas in the dento-alveolar region. It is important to study the response of dental tissues to orthodontic forces and the resultant effect to minimize risk of tissue damage. Finite element model is an effective method to understand this biomechanical scenario.
Aim: To study the effect of intrusion utility arch in anterior maxillary dento-alveolar region.
Materials and Methods: FEM of maxillary dento-alveolar region. Intrusion scenario of 4 incisors using intrusion utility arch was simulated. The effects on PDL, tooth and alveolar bone were analyzed.
Result: Maximum tensile stresses are in the cervical region of labial surface of incisors, PDL and alveolar bone which are becoming compressive at apices.
Conclusion: Above method is found safe for PDL and alveolar bone but suggested susceptibility to root resorption.

Keywords: Intrusion, FEM, Stresses.
