Table 4 Vertical displacements in group I and group II consolidated and non-consolidated models (mm)

From: Evaluating the effects of consolidation on intrusion and retraction using temporary anchorage devices—a FEM study

  1. Inference: (positive (+) : intrusion; negetive(-): extrusion)
  2. Group I: In consolidation, extrusion of canines and centrals observed in all cases, laterals extruded in 10-mm implant height and in other models intrusion of laterals observed. In non-consolidation, extrusion of canines observed in all cases whereas laterals showed extrusion in 10-mm implant height and centrals showed extrusion in 7-mm implant height, intrusion of centrals and laterals observed in 13-mm implant height model
  3. Group II: In consolidation and non-consolidation, extrusion of canines observed and centrals and laterals intruded in all models
