一般注記We examined the facial characteristics of Chinese children with high angle craniofacial morphology using Steiner analysis. Sixty-four boys and 61 girls were selected from a clinic in Hangzhou, Zhejiang Province, China. The Chinese children with high angle craniofacial morphology had significantly larger U1 to NA (mm), U1 to NA (angle), L1 to NB (mm), and SE, and significantly smaller ∠SNA, ∠SNB, ∠ANB, ∠SND, L1 to NB (angle), Interincisal angle, ∠Occl to SN, ∠GoGn to SN, and SL compared with Chinese adult high angle cases. Compared to measurements of Chinese at developmental stage IIIC skeletal 1 cases, ∠ANB, U1 to NA (mm), U1 to NA (angle), L1 to NB (mm), ∠Occl to SN, ∠GoGn to SN, and SE were significantly larger, and SNA, ∠SNB, ∠SND, Interincisal angle, and SL were significantly smaller. These results demonstrated a skeletal pattern of maxillary and mandibular growth in the anterior direction, and the mandible in particular exhibited vigorous downward growth and retrusion due to clockwise rotation. Regarding the denture pattern, although we found that the excessive labial inclination of the maxillary and mandibular anterior teeth improved with age, the cant of the occlusal plane increased.
