Background: Space closure by en masse intrusion and retraction in orthodontics is of particular interest. Aim: The aim of this study was to evaluate the stress distribution and displacement of maxillary anterior teeth. Materials and Methods: Four different finite element models of maxillary arch were constructed to understand the nature of stresses and displacement patterns of anterior teeth during en masse intrusion and retraction on force application with different combinations of mini-implants and retraction hooks. Results: In this study, tensile stresses were seen in the cervical region and various movements of teeth such as lingual crown tipping, bodily movement, lingual root tipping, intrusion, and extrusion were observed. Conclusion: Nature of stresses changes from tensile to compressive from cervical area to apical area. Various tooth displacements suggest that different combinations of mini-implants and retraction hooks affect the direction of the tooth movement.

Orthodontic banding still finds its place in day today clinical practice of orthodontics. Well-prepared orthodontic bands provide adequate mechanical retention, which is further enhanced when cemented with glass-ionomer luting cements. Banded molars withstand the occlusal forces better than their bonded counterparts. Composite veneering of these orthodontic bands can mask the objectionable metallic appearance of the orthodontic bands for better esthetics and acceptance
