Reference plane for measurement.

<p>A. Front view of reference plane; B. Skull base view of reference plane, and three points were identified to ensure the reference plane: a, midpoint of the left greater palatine foramen; b, midpoint of the right greater palatine foramen; c, the forefront of the nasal crest.</p

Intra-oral photos of the mini-screw implants.

<p>A. The mini-screw implant was placed between the upper first molar and the second molar on the buccal side; B. The mini-screw implant was placed between the first molar and the second premolar on the palatal side.</p
