Comparison of tooth movement in BIOSTAR group with and without attachments. A. Crown measurement. B. Root measurement. C. Long axis measurement. The bar attachment group showed a larger mesial root torque than the ellipsoid attachment groups. Comparison of tooth movement in the TPU group with and without attachments. D. Crown measurement. E. Root measurement. F. Long axis measurement. The bar attachment group had a longer long axis angle than either the ellipsoid attachment groups or the group with no attachments.
