摘要
目的:探讨新疆地区Ⅱ类骨型患者的颅面形态特征。方法:应用电子计算机X线头影测量系统,对50 例新疆地区汉族青少年Ⅱ类骨型患者的相关指标进行测量和分析。结果:新疆地区汉族青少年Ⅱ类骨型患者从错(牙合)机制角度、矢状向可分为4类,垂直向可分为3类。矢状向发育不调以上颌正常下颌后缩型最多见(40%),上颌前突下颌正常型居其次(28%)。Ⅱ类骨型患者中60%存在垂直向发育不调;上颌正常下颌后缩型以垂直发育过度为主;上颌前突下颌正常型以垂直发育不足为主。结论:在临床矫治时,应结合多项头影测量指标进行综合分析,根据不同的机制设计不同的矫治方案。
Objective： To investigate the characteristics of craniofacial conformation in skeletal pattern Ⅱ patients in Xinjiang. Method： Fifty lateral radiographs were measured and analysised by the computerized cephalometric radiography system. Results： There were 4 types in sagittal of skeletal pattern Ⅱ adolescents, and 3 types in vertical. The disharmony of sagittal was seen in the type of normal maxilla and recessive mandible most commonly. There were almost 60 percent patients of vertical disharmony in skeletal pattern Ⅱ. Conclusion： Several comprehensively in diagosis and
