一般注記We examined the facial characteristics of Chinese adults with high angle craniofacial morphology using Steiner and Downs analyses. Twenty-one males and 56 females were selected from a clinic in Tainan City, Taiwan. Angular and linear measurements were determined. In comparison with pre-existing measurement values for Chinese adults with maxillary protrusion, the L1 to NB (angle), ∠Occl to SN, and ∠GoGn to SN were significantly larger, while the SNA angle, SNB angle, SND angle, U1 to NA (mm), L1 to NB (mm), Interincisal angle, and SL were significantly smaller. Compared to measurement values of Chinese children in Hellman’s developmental stage IIIC with maxillary protrusion, the SNA angle, SNB angle, ANB angle, SND angle, L1 to NB (angle), ∠Occl to SN, ∠GoGn to SN, and SL were significantly larger among subjects in the present study; while the U1 to NA (mm), U1 to NA (angle), L1 to NB (mm), Interincisal angle, and SE were significantly smaller. These results demonstrate that marked clockwise rotation of the mandible in the skeletal patterns was presumed to be the result of increased vertical growth. In regard to denture patterns, there was increasing labial inclination of the mandibular anterior teeth and the clockwise rotation of the occlusal plane as the dental compensation for the skeletal changes.
