Inference (positive(+) : palatal movement; negative(-): labial movement)
Group I: In consolidation, palatal tipping is seen, and in non-consolidation, labial flaring is seen in lateral incisor
Group II: In consolidation, 10-mm implant height model showed bodily movement, 7- and 13-mm implant height showed palatal tipping and in non-consolidation, labial flaring of the teeth observed in centrals and laterals
