The samples consisted of 15 Korean young adult patients with skeletal Class III malocclusion (9 males and 6 females; mean age, 22.3 years).

Paired t-test was performed.

SNA, Sella-nasion-point A angle; SNB, sella-nasion-point B angle; ANB, point A-nasion-poing B angle; A-N perp, point A-nasion perpendicular line; Pog-N perp, pogonion-nasion perpendicular line; FMA, Frankfort horizontal plane to mandibular plane angle; U1 to FH, maxillary incisor inclination to Frankfort horizontal plane; IMPA, incisor mandibular plane angle; SD, standard deviation.
