摘　　要：目的:研究成人骨性III类错患者软硬组织二者之间的相关性,并间接了解对软组织侧貌影响较大的硬组织指标,为临床诊断和治疗设计提供指导。方法:对20例成人骨性III类错牙合患者进行软硬组织X线头影测量,所得数据用SPSS软件做相关性分析。结果:多数软硬组织侧貌美学指标有明显的相关性。影响的软组织美学指标最多硬组织测量项目依次为:SND、1-T、SNB、T-NB、T-NB(mm)、ANB、1-NA、1-NA(mm)、SNA、FMIA。结论:成人骨性III类错患者硬组织面型构成了软组织面型的基础和支架,影响的软组织美学指标最多硬组织测量项目多集中在面型的下1/3处,即下颌骨区。Objective To investigate the relationship of the hard and soft tissues in patients with skeletal class Ⅲ malocclusion. Methods All 20 patients in this research were diagnosed to be skeletal class Ⅲ malocclusion. The lateral X-ray cephalometric films were analyzed for the relationship of the hard and soft tissues by the SPSS software. Results Most items of the hard tissue were closely related with the items of the relevant soft tissue. The items of the hard tissue which effected the soft profile orderly were：SND,1-T,SNB,T-NB,T-NB（mm）,ANB,1-NA,1-NA （mm）,SNA,FMIA. Conclusion For the patient with skeletal class III malocclusion, the skeletal profile is the frame and basis of the soft profile of the face. The most related items of the hard tissue focus to the low 1/3 face.
